Frequently Asked Questions
Can I use the MFM-20-5 for 5V single-board computers or embedded controllers?
Yes, it provides a constant voltage 5V output with up to 4A available, which fits many single-board computers, embedded controllers, and digital processing boards that need a stronger 5V rail. Its 20W power rating gives more headroom than the 5W, 10W, and 15W 5V versions in the same series.
Is the MFM-20-5 suitable for 5V industrial USB or logic-powered devices inside equipment?
It can be used for 5V logic-powered industrial electronics as long as the total load stays within 4A and 20W. Because it is a constant voltage model, it is intended for equipment that expects a regulated 5V supply rather than a higher-voltage rail.
Can this model power a compact HMI, gateway, or communications board that runs on 5V?
That is a typical fit if the device needs a stable 5V rail and draws no more than 4A. The PCB type format and 49.0 x 23.8 x 23.0 mm dimensions also make it easier to place inside compact control and communications hardware.
Is the MFM-20-5 meant for indoor or outdoor use?
This model does not list an IP rating, so it should not be treated as a sealed outdoor power supply. It supports an operating temperature range of -35C to +85C, but it is better suited to protected indoor assemblies where the PCB type supply is shielded from direct moisture and dust.
How does the MFM-20-5 compare with the other 5V models in the MFM family?
Within the 5V range, the available models are MFM-05-5 at 5W and 1A, MFM-10-5 at 10W and 2A, MFM-15-5 at 15W and 3A, MFM-20-5 at 20W and 4A, and MFM-30-5 at 30W and 6A. The MFM-20-5 sits one step below the highest-capacity 5V option while offering more output current than the 5W, 10W, and 15W versions.
