■ Description

IRM-45 is a 45W miniature (87*52*29.5mm) 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 universal input voltage range of 85~305VAC. The 94V-0 the flame retardant plastic 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 90.5% and the extremely low no-load power consumption below 0.25W, IRM-45
series fulfills the worldwide regulation for the low power consumption requirement for electronics. The
entire series is a Class design (no FG pin), incorporating the built-in EMI filtering components, enabling Ⅱ
the compliance with EN55032 Class B; the supreme EMC features keep the end electronic units from
electromagnetic interference. In addition to the PCB mounting style model, IRM-45 series also offers the
screw terminal style model (ST).

PACKING

1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 of ambient temperature.℃

2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.

3. Tolerance : includes set up tolerance, line regulation and load regulation.

4. The ambient temperature derating of 3.5 /1000m with fanless models and of 5 /1000m with fan models for operating altitude higher than 2000m(6500ft).℃℃

5. The power supply is considered as an independent unit ,but the final equipment still need to re-confirm that the whole system complieswith the EMC
directives. For guidance on how to perform these EMC tests, please refer to EMI testing of component power supplies.
