Description
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 equipment. 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 fundamental resistance to dust and moisture. With the high efficiency of up to 80% and the extremely
low no-load power consumption of below 0.075W, the IRM-03 series fulfills the worldwide regulation for the low power consumption requirement for electronics. The entire series is a Class design (no FG pin), Ⅱ incorporating the built-in EMI filtering components, enabling compliance with BS EN/EN55032 Class B; the supreme EMC features keep the end electronic units from electromagnetic interference. In addition to the module-type model, the IRM-03 series also offers the SMD style model.
