Information on MEAN WELL EPP-200-48

The MEAN WELL EPP-200-48 is a highly compact, 200 W open-frame AC/DC power supply built into a standard 4" x 2" footprint featuring high power density and an active PFC function. Designed for versatile installation, it operates across a universal input range of 80 to 264 V AC and delivers a regulated single 48 V DC output. It provides up to 2.95 A (141.6 W) under free air convection cooling, and up to 4.22 A (202.5 W) when provided with 10 CFM of forced air cooling.

Featuring an exceptional efficiency rating of up to 93% and a no-load power consumption of less than 0.5 W, the EPP-200-48 supports both Class I (with FG) and Class II (no FG) system designs. It also includes an auxiliary 12 V / 0.5 A output specifically dedicated to powering an external cooling fan. Comprehensive protections against short circuit, overload, overvoltage, and overtemperature are integrated as standard. Fully compliant with international safety and EMC standards, the module includes a 3-year manufacturer warranty.
