Information on MEAN WELL EPP-300-24

The MEAN WELL EPP-300-24 is a highly reliable, 300 W open-frame AC/DC power supply built into a compact 5" x 3" footprint featuring high power density and an active PFC function. Designed for versatile installation, it operates across a universal input range of 90 to 264 V AC, can withstand a 300 VAC surge input for 5 seconds, and delivers a regulated single 24 V DC output. It provides up to 8.33 A (200 W) under free air convection cooling, and up to 12.5 A (300 W) when provided with 20.5 CFM of forced air cooling.

Featuring an exceptional efficiency rating of up to 93% and an extremely low no-load power consumption below 0.5 W via PS-ON control, the EPP-300-24 supports energy-efficient system design. It includes advanced built-in features such as a 5V standby output, a 12V fan supply, Power Good/Fail signals, and a remote sense function. 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.
