Details
Meanwell IRM-45-12 is a 45W miniature (87*52* 29.5mm) AC-DC module-type power supply with 12V3.8A0-3.8A45.6W150mVp-p. This unit is ready to be soldered onto the PCB boards of various kinds of electronic instruments or industrial automation equipment. Meanwhile, it accepts the universal input voltage range of 85~305VAC. The 94V-0 flame retardant plastic case and the fully-potted silicone boost the heat dissipation. PCB mounting style model (Blank) meet the anti-vibration demand up to 2G, and screw terminal style model (ST) meet the anti-vibration demand up to 5G. In addition, IRM-45-12 gives the fundamental resistance to dust and moisture. With the high efficiency up to 90.5% and the extremely low no-load power consumption below 0.15W, the product fulfills the worldwide regulation for the low power consumption requirement for electronics. As it is designed Class Ⅱ (no FG pin), incorporating the built-in EMI filtering components, IRM-45-12 enables the compliance with BS EN/EN55032 Class B. The supreme EMC features protect the end electronic units from electromagnetic interference. Except for the PCB mounting style model, IRM-45-12 provides the screw terminal style model (ST). Thanks to the high reliability, low cost and longevity, Meanwell IRM-45-12 is perfect for various Industrial electrical applications.
