Mean Well IRM-20-5 Switching Power Supply 3W 5V 4A - Encapsulated

Yes, this model provides constant-voltage 5V output up to 4A, with 20W total power. That makes it suitable for 5V embedded controllers, SBCs, and supporting logic hardware that stay within that load range. It accepts 85-305VAC input for direct AC-powered equipment designs.

It can be appropriate for internal 5V logic and peripheral rails if the combined load does not exceed 4A. The fixed 5V output suits many digital boards, interface modules, and low-voltage automation electronics. The encapsulated PCB-mount construction is intended for integration on the board side of equipment.

Yes, for 5V display and control electronics that operate within 20W and 4A. That includes low-voltage HMI controller boards or display logic sections that need a regulated 5V rail. The miniature 52.4 x 27.2 x 24.0 mm package helps in compact equipment layouts.

It can fit a compact automation gateway or edge device when the device runs on 5V DC and remains under 4A. The unit weighs 0.05 kg and uses an encapsulated miniature form factor, which supports small internal assemblies. This is a constant-voltage supply, so it is intended for fixed 5V loads rather than variable-output requirements.

The operating temperature range is -30C to +70C, so the temperature spec is broad for internal equipment use. The provided specifications do not include an IP rating, which means outdoor or washdown suitability should not be assumed. It is best used inside a protected enclosure.
