Overview

IRM-01-12 is the 12V output model of this series: rated current 83mA, rated power 1W, typical efficiency 74%.

IRM-01 is a 1W miniature (33.7*22.2*15mm) AC-DC module-type power supply, ready to be soldered onto the PCB boards of various kinds of electronic instruments or industrial automation equipments. This product allows a universal input voltage range of 85~305Vac. The phenolic case and potted with silicone enhance the heat dissipation and meet the anti-vibration demand up to 5G; moreover, it provides the fundamental resistance to dust and moisture. With the high efficiency up to 77% and the extremely low no-load power consumption below 0.075W, IRM-01 series fulfills the worldwide regulation for the low power consumption requirement for electronics. The entire series is a Class Ⅱ design (no FG pin), incorporating the built-in EMI filtering components, enabling the compliance with BS EN/EN55032 Class B; the supreme EMC features keep the end electronic units from electromagnetic interference.

FAQ

Can I use the IRM-01-12 for a small 12V industrial control circuit?

Yes, if the control circuit needs a constant 12V DC supply and stays within the 1W, 83mA output limit. It is a better fit for low-power industrial monitoring, interface, or control electronics than for heavier 12V loads.

Is the IRM-01-12 suitable for an embedded 12V sensor or alarm board?

It can work for compact embedded 12V boards that use constant voltage and draw no more than 83mA from a 1W supply. The miniature encapsulated design and 33.7 × 22.2 × 15.0 mm size also suit tight board-level space.

Can this power a low-draw 12V auxiliary rail in IT or telecom equipment?

It is appropriate for very low-power 12V auxiliary rails where the load stays within 1W and 83mA. Buyers should treat it as a small constant voltage supply for board-level support functions, not for higher-current 12V equipment.

How does the IRM-01-12 compare with other low-power IRM models?

In the 1W IRM-01 series, sibling outputs are 3.3V 300mA, 5V 200mA, 9V 111mA, 12V 83mA, 15V 67mA, and 24V 42mA, all in the same 33.7 × 22.2 × 15 mm encapsulated package with 85-305VAC input. The IRM-01-12 has 74% typical efficiency and 150mVp-p max. ripple; if you need more than 1W at 12V, a higher-power supply is required.

Is the IRM-01-12 suitable for outdoor or harsh-temperature use?

The operating temperature range is -30°C to +85°C, with output derating at higher ambient temperatures per the derating curve. An IP rating is not listed, so indoor or outdoor exposure suitability is not specified by the provided specs.
