FAQ

Can I use the IRM-01-5 for a small 5V embedded controller or logic board?

Yes, if the 5V load is a low-power circuit and stays within the 1W rating. This constant voltage model is suited to compact embedded or automation electronics that need a regulated 5V rail from an 85-305VAC input.

Is the IRM-01-5 appropriate for a low-power industrial interface or monitoring module?

It can be, provided the module is designed for 5V DC and does not exceed 1W. That makes it a better match for small monitoring, logic, or communications sections than for heavier 5V equipment.

Can this 5V model be used on a PCB for compact automation electronics?

Yes, the 33.7 × 22.2 × 15.0 mm size and miniature encapsulated PCB mounting style support compact board-level designs. The 5V constant voltage output is intended for onboard low-power electronics rather than larger 5V subsystems.

Is the IRM-01-5 meant for outdoor use or only protected indoor enclosures?

The unit is rated for -30°C to +85°C operation, with output derating at higher ambient temperatures per the derating curve. No IP rating is provided, so it should be considered for protected internal use instead of exposed outdoor or washdown environments.

How does the IRM-01-5 compare to nearby IRM voltage options?

At the 1W level, the IRM-01 series includes 3.3V 300mA, 5V 200mA, 9V 111mA, 12V 83mA, 15V 67mA, and 24V 42mA outputs, all in the same 33.7 × 22.2 × 15 mm encapsulated package. The 5V model has 70% typical efficiency; if 1W is not enough, a higher-power supply is needed.
