Details
Meanwell IRM-20 Series is a 20W miniature (52. 4*27.2* 24mm) AC-DC module-type power supply. They are ready to be soldered onto the PCB boards of various kinds of electronic instruments or industrial automation equipment. Apart from them, the series allows the universal input voltage range of 85~305VAC. The 94V-0 flame retardant plastic case and the fully-potted silicone enhance the heat dissipation and meet the anti-vibration demand up to 2G. Moreover, IRM-20 series provides the fundamental resistance to dust and moisture. With the high efficiency up to 85% and the extremely low no-load power consumption below 0.1W, Meanwell IRM-20 series fulfills the worldwide regulation for the low power consumption requirement for electronics. Since the entire series is a Class II design (no FG pin), incorporating the built-in EMI filtering components, it enables the compliance with BS EN/EN55032 Class B. The supreme EMC features keep the end electronic units from electromagnetic interference. Due to the high reliability, low cost and longevity, Meanwell IRM-20 Series is ideal for various Industrial electrical applications.
