Overview

IRM-01-5S is the 5V output model of this series: rated current 200mA, rated power 1W, typical efficiency 70%.

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 the fully-potted 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 EN55032 Class B; the supreme EMC features keep the end electronic units from electromagnetic interference. In addition to module-type model, IRM-01 series also offers the SMD style model.

FAQ

Can I use the IRM-01-5S for a compact 5V embedded or automation PCB?

Yes, this version is intended for low-power 5V DC electronics where 1W is sufficient. Its miniature encapsulated construction, SMD style, and 33.7 × 22.2 × 16.0 mm dimensions make it relevant for dense board layouts with onboard AC-to-DC conversion.

Is the IRM-01-5S suitable for a small industrial control or communications circuit?

It can be suitable when the circuit uses a regulated 5V rail and remains within the 1W rating. This is the right scale for low-consumption control, monitoring, or communications electronics, not for high-current 5V loads.

Can the IRM-01-5S be used for low-power IT or appliance control boards?

Yes, for small 5V constant voltage sections that need direct conversion from 85-305VAC. The package is designed for embedded board use, so it fits compact internal electronics better than standalone higher-power equipment.

Does the IRM-01-5S support outdoor or high-temperature conditions?

The operating range is -30°C to +85°C, which covers wide ambient conditions. Since no IP rating is listed, it should be used inside a protected enclosure rather than in exposed outdoor locations.

What other IRM outputs should I compare against the IRM-01-5S?

The 1W IRM-01 range includes 3.3V 300A, 5V 200A, 9V 111A, 12V 0.08A, 15V 0.07A, and 24V 0.04A models, with standard and S versions across several voltages. Beyond that, IRM-02 through IRM-90 siblings raise power from 2W to 90.2W and extend voltage choices from 3.3V to 48V.
