Review, teardown, and testing of LRS-75-24 Mean Well power supply

General description

LRS-75-24 is a 24-volt power supply with a maximum current of 3.2 amperes. According to the manufacturer, the unit operates at a mains voltage of 100 to 240 volts without an additional switch. It has no PFC function. The supply measures approximately 4 × 4 × 1 1/5 inches (99 × 97 × 30 millimeters) and is made on a printed circuit board fixed to the base of the metal case. The top cover is perforated, and the holes are meant for passive cooling.

The input and output circuits are connected to a common screw block (1). From right to left, there are 3 terminals for the input line, neutral, and ground wires, and terminals 4 and 5 are the outputs: ground and +24V. The input voltage goes to the fuse and inrush current limiter (2), then to the RF interference filter (3), and finally, to the diode bridge (4). The inrush current limiter has no markings; apparently, it is just an NTC. The rectified mains voltage is supplied to the 150 uF, 400V capacitor (5) and then to the flyback converter built on an MW03A controller (located on the back side of the PCB), a TK750A60F transistor (6), and a transformer (7). The voltage from the secondary winding of the transformer is rectified by a Schottky diode HBR20150 (8) and supplied to storage capacitors 2×470uF 35V, and, through an additional LC filter (10) (11), goes to the output. The feedback circuit is classic; with TL431 (on the other side of the board), the feedback signal is transmitted to the PWM controller through one of the optocouplers (12); the second optocoupler forms a backup channel for overvoltage protection at the OVP output. The installed electrolytic capacitors are designed for operating temperatures up to 220F (105C). The bulkiest of them, the input one, is held on the board with compound.

Build quality is good.

The power transistor (6) and diode (8) are pushed against the metal case using spring brackets to dissipate heat. Their own housings are insulated using special shells.

Test conditions

Most tests are performed using Metering Setup #1 (https://teardownit.com/posts/power-control-unit-for-testing) at 80F (27C), 70% humidity, and 29.8 inHg pressure. The measurements were performed without preheating the power supply with a short-term load unless mentioned otherwise. The following values were used to determine the load level:

It should be noted that there is a slight overshoot; increasing the load slightly increases the output voltage.

Power-on parameters

Powering on at 100% load

Before testing, the power supply is turned off for at least 5 minutes with a 100% load connected. The oscillogram of switching to a 100% load is shown below (channel 1 is the output voltage, and channel 2 is the current consumption from the grid):

The picture shows three distinguishable phases of the power-on process:

When connected to the grid, the pulse of the input current charging the input capacitors has an amplitude of about 5.7 A and a duration of 6 ms.

Waiting for the power supply control circuit to start for about 117 ms.

(Output Voltage Rise Time) Starting the converter, increasing the output voltage, and entering the operating mode takes 6 ms.

(Turn On Delay Time) The entire process of entering the operating mode from the moment the device powers on is 123 ms.

(Output Voltage Overshoot) The switching process is aperiodic; there is no overshoot.

Power-off parameters

The power supply was turned off at 100% load, and the input voltage was nominal at the moment of powering off. The oscillogram of the shutdown process is shown below:

The oscillogram shows two phases of the shutdown process:

(Shutdown Hold-Up Time) The power supply continues to operate because the input capacitors hold charge until the voltage across them drops to a certain critical level, at which point maintaining the output voltage at the nominal level becomes impossible. The phase takes 16 ms.

(Output Voltage Fall Time) Reduction of the output voltage, stopping voltage conversion, and accelerating the voltage drop takes 19 ms.

(Output Voltage Undershoot) The shutdown process is aperiodic; there is no undershoot.

The amplitude of the current at 100% load before shutting down is approximately 3 A.

Output voltage ripple

100% load

At 100% load, the low-frequency ripple is approximately 20 mV.

At 100% load, the ripple at the converter frequency is approximately 50 mVp-p.

75% load

At 75% load, the low-frequency ripple is approximately 40 mV.

At 75% load, the ripple at the converter frequency is approximately 35 mVp-p.

50% load

At 50% load, the low-frequency ripple is approximately 20 mV.

At 50% load, the ripple at the converter frequency is approximately 40 mVp-p.

10% load

At 10% load, the low-frequency ripple is approximately 10 mV.

At 10% load, the ripple at the converter frequency is approximately 20 mVp-p, and the noise is 80 mVp-p.

0% load

The no-load current consumption measured with a multimeter is 18 mA. The current consumption in this mode is predominantly reactive. In the supply circuit, the input filter contains a 0.47 uF capacitor.

(Power Consumption) It is not possible to measure the exact active power consumption at a 0% load with a basic set of instruments (oscilloscope, multimeter, etc.).

At 0% load, the low-frequency ripple is approximately 10 mV.

At 10% load, ripples at the converter frequency are masked by the 90 mVp-p noise.

Dynamic characteristics

A mode with periodic switching between 50% and 100% load was used to evaluate the dynamic characteristics. The oscillogram of the process is shown below:

The supply’s response to load changes is a bit shaky. The magnitude of the response to load changes reaches 200 mV.

Overload protection

The claimed protection type is "hiccup mode, which recovers automatically after the fault condition is removed." This was confirmed during testing. When a short circuit occurs, the power supply periodically tries to turn back on and, if the overload is still present, turns off again until the next attempt. This operating mode reduces energy losses and heating during overload. Still, it does not allow the parallel connection of multiple power supplies with a common output.

The output current for the overload protection to kick in is 5 A.

Input circuit safety assessment

(Input discharge) Safety assessment is based on the discharge time constant of the input circuits when disconnected from the grid; the value is 0.234 s. This means that when operating on a 120 V input voltage, the time required to discharge the input circuits to safe values (<42 V) will be 0.37 s:

Important: The result is valid for this particular power supply unit; it was obtained for testing purposes and should not be taken as a safety guarantee.

The leakage current at the ground pin is about 11 µA.

Thermal conditions

When operating with no load connected, no component overheating had been noticed. Thermograms were captured at three power levels: 80, 90, and 100%, fully assembled and with the lid removed. Thermal images show that the most loaded element of the block is the input thermistor (NTC), and its heating seriously stands out against the background of all the other components. At 80% load, it heats up to 197F (92C, 117F above ambient temperature). At 90%, it's 214F (101C, 134F above ambient), and at 100%, it reaches 227F (108C, 147F above ambient).

80% load

90% load

100% load

Conclusions

Overall, the LRS-75-24 is a solid unit. It's noise and ripple are acceptable for many applications, the output voltage is maintained accurately, and the build quality is decent. However, the dynamic characteristics of this power supply are not that good. When load pulses, one can notice large surges and quite some ripple, indicating some circuit design downsides in terms of its frequency characteristics. For long-term operation, the load should be limited to 80–90% of the nominal one, especially during the hot season when ambient temperatures reach 95F (35C) or more.

Important: The results are valid for this particular power supply unit; they were obtained for testing purposes and should not be used to evaluate all the units of the same type.

Compatibility Guide for CORSAIR MP600 Elite 2 TB NVMe SSD

CORSAIR MP600 Elite

Under severe loads, the Corsair MP600 Elite’s heatsink keeps the drive cool. Hot SSDs slow down, therefore this is crucial. The low-profile heatsink fits most laptops and desktops.

Advantages of the CORSAIR MP600 Elite:

Game and app loading is quicker with the Corsair MP600 Elite than with a SATA SSD.

Improved responsiveness: The Corsair MP600 Elite might make your system seem quicker and snappier.

The MP600 Elite’s fast speed reduces game latency and stuttering.

Creative workers: The Corsair MP600 Elite is ideal for creative professionals that work with huge files like images and films. The quick speeds boost productivity and workflow.

The CORSAIR MP600 Elite is suitable for rapid storage. Gamers and creatives that demand maximum performance will love it. However, it is a pricey SSD, so examine the pros and cons before buying.

Corsair offers three MP600 Elite models. Like, the first version has a black aluminium heat sink. The PlayStation 5-inspired version has a white heat sink. A third option, Corsair’s heat sink-free version, is ideal for notebooks or motherboard coolers.

The Corsair MP600 Elite is an 8-cm M.2 with PCIe 4.0 x4. The cheaper MP600GS can read and write at 4,800 and 4,500 MB/s, while the Pro XT can read and write at 7,100 and 6,800. Corsair claims 7000 MB7s read and 6500 MB/s write for the MP600 Elite, just below the MP600 Pro XT. Will they notice this tiny theoretical disadvantage in practice or will performance differ even more?

The write speed of the storage medium depends on the amount of data written without interruption and the memory fill level. This is why life cycle write speed is hard to predict.

Controller NAND and Dynamic pSlC cache

Corsair uses soft, sticky pads to dissipate the 5 to 7 watts peak (measured) at maximum load from the top. After removing these, you can see the TECHVEST PCB, customised and assembled for Corsair. The Corsair MP600 Elite deliberately uses the smaller and cheaper Phison E27 instead of the faster Phison E18.

This has four NAND channels and one core (three with the co-processor), half of the Pro XT. From Windows 10, the SSD uses the host memory buffer to access the computer’s system RAM instead of a DRAM cache. This is fine because this standard NVMe feature usually compensates for the lack of a DRAM cache.

The 12nm-processed E27T controller uses PCIe 4.0. The E27T is DRAM-less despite its 7,400 MB/s read and 6,700 MB/s write speeds. This method simplifies SSD design and may reduce production costs. The low-power PCIe Gen 4 SSD controller is designed for 2230 M.2 SSDs, which are used in handheld gaming devices like the Steam Deck and ROG Ally.

This controller uses TSMC’s 12nm process and Phison’s “Single CPU Architecture”. The Gen 4 PS5027-E27T controller supports 8TB of storage and 3D TLC and QLC NAND flash, like the PS5031-E31T. Sequential performance can reach 7,400MB/s read and 6,700MB/s write, and random performance can reach 1,200,000 IOPS.

NAND flash manufacturers advise against dynamically changing flash block configurations as pSLC or TLC memory for reliability reasons, but in the consumer sector, where temperature windows are less important, this is more relaxed.

The Phison E27T supports NVMe 1.4 and has many standard functions. It supports Trim and S.M.A.R.T. It uses ASPM, APST, and L1.2 ultra-low power status like other controllers. In most applications, thermal throttling is unnecessary because the controller does not overheat.

For robust error correction and data reliability, it uses the fourth generation LDPC ECC engine, SmartECC (RAID ECC), and end-to-end data path protection. A crypto-erase function and hardware-accelerated AES 128/256-bit encryption (TCG, Opal 2.0, and Pyrite compliant) are included. Phison E27T supports a fully dynamic write cache. Phison also uses SmartFlush for fast cache recovery and consistent performance.

When the great cache performance ends is unknown. After exactly 47.98 GB in one piece, the glory ended, and at more than 80% capacity, you’re only at mediocre SATA. You’ll barely be able to do that, but it’s better to fill up slowly and possibly more often.

An empty (but not virgin) SSD shows that the dynamic pSLC works as intended. The 2 TB SSD has plenty of space, so never fill it more than 2/3 full. A higher load does not affect reading, but the dynamic SLC will max out when writing. It will become impossible to switch memory modules between the two methods if you do it repeatedly. Even though the figures are smaller, the cache still matters, synthetic benchmarks should not be taken too seriously, especially if the firmware has been optimised for them.

A video stream

What happens when you stream a bigger video? For this, the industry uses the AJA benchmark, which bridges synthetic benchmarks and practical applications. Due to the trimmed cache, the Corsair MP600 Elite fails brutally here, especially since it already deviates from the theoretical write and read rate. The comments on the previous page about the dynamic pSLC cache and larger file blocks are correct. Caching collapses at just under 48 GB.

Applications benchmark Overview and conclusion

Let’s compare the MP400 (QLC), MP600 GS (QLC), and MP600 Pro XT (TLC) in a workstation. The Corsair MP600 Elite performs well in the middle of the tested models, while the QLC variants lose significantly in every case (also subjectively noticeable). In writing, many programmes weaken greatly, with the MP600 PRO XT leading and the Corsair MP600 Elite almost reaching MP600-GS levels. Due to its neutered cache, the Corsair MP600 Elite writes like the GS rather than the Pro XT.

Reading is similar, except for NAMD, and the performance boost over the cheap MP600 GS is still extreme, but more pronounced than the slight writing advantage. The cache doesn’t matter when reading, and Aja’s value is confirmed again because theory and practice don’t match.

Performance is sufficient for applications. You have to consider whether you really feel it subjectively and whether it increases productivity in the individual case enough to justify the surcharge compared to an MP600 PRO GS or whether you should go straight for the Pro XT if you want more and want Corsair.
