Details
Meanwell IRM-05-3.3 is a 5W miniature (45.7*25 .4*21.5mm) AC-DC module-type power supply with 3.3V1.25A0-1.25A4.125W200mVp-p. This item is ready to be soldered onto the PCB boards of various kinds of electronic instruments or industrial automation equipment. And it allows the universal input voltage range of 85~305VAC. The 94V-0 flame retardant plastic case and the fully-potted silicone improve the heat dissipation and fit the anti-vibration demand up to 5G. in addition, IRM-05-3.3 offers the fundamental resistance to dust and moisture. With the high efficiency reaching up to 77% and the extremely low no-load power consumption below 0.1W, Meanwell IRM-05-3.3 fulfills the worldwide regulation for the low power consumption requirement for electronics. As IRM-05-3.3 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 E MC features keep the end electronic units from electromagnetic interference. Thanks to the high reliability, low cost and longevity, Meanwell IRM-05-3.3 is an ideal solution for various Industrial electrical applications.
