IRM-90 is a 90W miniature(87*52*29.5mm) AC-DC PCB-mount 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 the universal input voltage range of 80~305VAC.The 94V-0 flame retardant plastic case and potted with silicone enhance the heat dissipation and meet the anti-vibration demand up to 2~5G anti-vibration by model; moreover, it provides the fundamental resistance to dust and moisture. With the high efficiency up to 93% and the extremely low no-load power consumption below 0.3W IRM-90 series fulfills the worldwide regulation for the low power consumption requirement for electronics. The entire series is a Class Idesign(no FGpin),incorporating the built-in EMl filtering components, enabling the compliance with BS EN/EN55032 Class B: the supreme EMC features keep the end electronic units from from electromaanetic interference. in addition to the PCB mountina stvle model.IRM-90 series also offers the screw terminalstyle model (ST).
