Details
Meanwell IRM-45-48 is a 45W miniature (87*52* 29.5mm) AC-DC module-type power supply with 48V0.94A0-0.94A45.12W300mVp-p. this model is ready to be soldered onto the PCB boards of various types of electronic instruments and industrial automation devices. In addition, it 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. 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. What’s more, IRM-45-48 provides the fundamental resistance to dust and moisture. With the high efficiency reaching up to 90.5% and the extremely low no-load power consumption below 0.15W, the unit conforms the worldwide regulation for the low power consumption requirement for electronics. Since it is designed Class Ⅱ (no FG pin), incorporating the built-in EMI filtering components, IRM-45-48 enables the compliance with BS EN/EN55032 Class B. The supreme EMC features keep the end electronic devices from electromagnetic interference. Except for the PCB mounting style model, IRM-45-48 provides the screw terminal style model (ST). In light of the high reliability, low cost and longevity, Meanwell IRM-45-48 is ideally suitable for various Industrial electrical applications.
