Details
Meanwell IRM-03-3.3 is a 3W miniature (37*24*15mm) AC-DC module-type power supply with 3.3V900mA0-900mA3W100mVp-p. The item is ready to be soldered onto the PCB boards of various kinds of electronic instruments or industrial automation equipment. Apart from them, it allows universal input voltage range of 85~ 305VAC. The phenolic case and the fully-potted silicone improve the heat dissipation and meet the anti-vibration demand up to 5G. In addition, IRM-03-3.3 provides the fundamental resistance to dust and moisture. With the high efficiency reaching up to 80% and the extremely low no-load power consumption below 0.075W, IRM-03-3.3 fulfills the worldwide regulation for the low power consumption requirement for electronics. Since the product is a Class Ⅱdesign (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. Except for the module-type model, IRM-03-3.3 also offers the SMD style model. Due to the high reliability, low cost and longevity, Meanwell IRM-03-3.3 is very suitable for various Industrial electrical applications.
