Information on MEAN WELL EPP-100-48

The MEAN WELL EPP-100-48 is a highly compact, 100 W open-frame AC/DC power supply built into a standard 4" x 2" footprint featuring an active PFC function. Designed for versatile installation, it operates across a wide universal input range of 90 to 264 V AC and delivers a regulated single 48 V DC output. It provides up to 1.6 A (76.8 W) under free air convection cooling, and up to 2.1 A (100.8 W) when provided with 20 CFM of forced air cooling.

Featuring an exceptional efficiency rating of up to 92.5% and a no-load power consumption of less than 0.5 W, the EPP-100-48 supports energy-efficient system design. It also includes an auxiliary 12 V / 0.3 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 Class B EMC requirements, the module includes a 3-year manufacturer warranty.
