Details
Meanwell IRM-20-12 is a 20W miniature (52. 4*27.2* 24mm) AC-DC module-type power supply with 12V1.8A0-1.8A21.6W200mVp-p. The unit is ready to be soldered onto the PCB boards of various kinds of electronic instrument or industrial automation equipment. At the same time, it accepts the universal input voltage range of 85~305VAC. The 94V-0 flame retardant plastic case and the fully-potted silicone combined enhance the heat dissipation and meet the anti-vibration demand up to 2G. Apart from them, IRM-20-12 provides the fundamental resistance to dust and moisture. With the high efficiency reaching up to 85% and the extremely low no-load power consumption below 0.1W, Meanwell IRM-20-12 fulfills the worldwide regulation for the low power consumption requirement for electronics. Since the product is designed Class II (no FG pin), incorporating the built-in EMI filtering components, it enables the compliance with BS EN/EN55032 Class B. The supreme EMC features protect the end electronic units from electromagnetic interference. In view of the high reliability, low cost and longevity, Meanwell IRM-20-12 is suitable for various Industrial electrical applications.
