Frequently Asked Questions
Can I use the IRM-03-24S to power a 24V industrial sensor or transmitter?
Yes, this model is a constant-voltage 24V supply rated at 3W with 125mA output. That makes it a fit for low-power 24V sensor, transmitter, or interface circuits that stay within a 125mA load budget.
Is the IRM-03-24S suitable for a compact automation control board?
It can be a good fit for compact automation boards that need a low-power 24V rail rather than a higher-current field supply. The miniature encapsulated SMD package measures 37.0 x 24.0 x 16.0 mm and provides up to 3W.
Can this 24V power supply be used for relay or signal interface circuits?
Yes, if the relay or interface section is designed for a 24V constant-voltage source and the total load does not exceed 125mA. The 3W rating makes it more appropriate for light-duty control and signaling functions than for larger 24V loads.
Is the IRM-03-24S appropriate for wide-input equipment sold into different AC regions?
Yes, its 85-305VAC input range supports equipment intended for varied mains environments. That wide input range is useful for industrial and embedded products that may be deployed across multiple regions while still needing a 24V output.
Can the IRM-03-24S be used outdoors or in harsh temperature conditions?
The operating temperature range is -30°C to +85°C, so it can handle a broad temperature span inside protected equipment. No IP rating is listed, so it is better suited to enclosed indoor or sheltered assemblies rather than exposed outdoor use.
How does the IRM-03-24S compare with other IRM low-power models?
Within the low-power IRM range, 24V options include IRM-01-24 and IRM-01-24S at 1W and 0.04A, IRM-02-24 and IRM-02-24S at 2W and 0.08A, IRM-03-24 at 3W and 125mA, IRM-05-24 at 5.52W and 0.23A, and IRM-10-24, IRM-15-24, IRM-20-24, IRM-30-24, IRM-45-24, IRM-60-24, and IRM-90-24 up to 90W and 3.75A. The IRM-03-24S sits at the 3W, 24V level in the SMD-style version.
