Megmeet MCP400WD-4.2/3.2 Dual Output Switching Power Supply
The Megmeet MCP400WD-4.2/3.2 is a dual output switching power supply for LED display assemblies that require +4.2V DC at 45A and +3.2V DC at 35A. This Megmeet power supply accepts 100–240V AC, 50/60Hz, with a listed maximum input current of 4.8A.
Use the complete model number and both output ratings when checking a replacement PSU. Compatibility depends on your LED module voltage requirements, the load on each output, and the cabinet’s wiring and mounting arrangement.
Electrical Specifications
| Parameter | Specification |
|---|---|
| Manufacturer | Megmeet |
| Model | MCP400WD-4.2/3.2 |
| Power supply type | Dual output switching power supply |
| AC input voltage | 100–240V AC |

| Maximum input current | 4.8A |
| Output 1 | +4.2V DC, 45A |
| Output 2 | +3.2V DC, 35A |
These electrical ratings match the product label shown in the photos below. The two outputs have different voltages; their current ratings should be checked separately against the intended loads.
Check Compatibility Before Ordering
- Match both DC voltages: confirm that your LED display requires the specified 4.2V and 3.2V supplies.
- Check each output load: compare the required current on each rail with its listed rating, and confirm any operating or derating requirements for your installation.
- Compare the physical layout: check the existing unit’s terminal positions, mounting holes and available cabinet space against the product photos and confirmed dimensions.
- Verify the complete model: compare the full label, including any suffix, before substituting another Megmeet PSU.

Frequently Asked Questions
What are the output voltages and currents?
Output 1 is +4.2V DC at 45A. Output 2 is +3.2V DC at 35A. Match each output to the corresponding load requirements.
Does this Megmeet PSU accept 100–240V AC?
Yes. The listed input is 100–240V AC at 50/60Hz, with a maximum input current of 4.8A.
Can it replace a single output 5V LED power supply?
It is not a direct voltage match for a 5V supply: this model is listed with 4.2V and 3.2V outputs. Confirm the display’s required supply voltages and wiring before choosing a replacement.
Is a total wattage rating confirmed for this model?
The available product label lists the two output voltage and current ratings. A separate total rated wattage and combined-load conditions are not specified here; confirm these details before sizing the supply by wattage.
What information helps confirm a replacement?
Provide the complete model label, required voltage and current for each output, terminal layout, mounting dimensions and cabinet clearance. A similar model name alone does not establish compatibility.
