FAQ

Can I use the IRM-02-24S in a surface-mount automation board that needs 24V DC?

Yes, this version provides 24V constant-voltage output at 2W and 83mA with an 85-305VAC input range. Its SMD style makes it relevant for compact 24V automation or control boards designed around surface-mount assembly.

Is the IRM-02-24S appropriate for powering a low-power 24V monitoring or alarm circuit?

It can be appropriate for low-power 24V monitoring, alarm, or signaling electronics that stay within the 2W and 83mA output limit. It is intended for small constant-voltage DC loads rather than heavier 24V field devices.

Can this model power a compact 24V embedded control module from worldwide AC input?

Yes, the 85-305VAC input range supports equipment intended for varied AC supply conditions, while the output remains 24V constant voltage. It is best suited to compact embedded modules whose 24V demand stays within 2W and 83mA.

What is the difference between IRM-02-24S and the other low-power IRM 24V models?

This datasheet covers only the 2W IRM-02 series, so it does not specify the other IRM 24V power levels. Within it, the IRM-02-24S is the SMD style version (33.7 × 22.2 × 16 mm) and the IRM-02-24 is the PCB mounting style version (33.7 × 22.2 × 15 mm), both rated 2W, 24V, 83mA.

Can the IRM-02-24S be used in exposed outdoor equipment?

An outdoor rating is not listed for this model. The specified environmental data is -30°C to +85°C operation, subject to the derating curve, and the encapsulated SMD format is more appropriate inside protected indoor assemblies than in directly exposed installations.
