IRM-03 is a 3W miniature (37*24*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 80% and the extremely
low no-load power consumption below 0.075W, IRM-03 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 EN55022 Class B; the
supreme EMC features keep the end electronic units from electromagnetic interference. In addition to
module-type model, IRM-03 series also offers the SMD style model.
