Improving switching power supply efficiency


Bel Fuse is expanding its line of EOS power supplies with the EPG300 and EPG500 series AC/DC power supplies based on new, efficient gallium nitride technology design. 

The supplies accommodate a universal input voltage of 90 to 264VAC, delivering up to 300W and 500W of output power with forced air cooling. The supplies are available in six single output voltages ranging from 12 to 58V. Both can be used in a range of space constrained applications where minimal power loss and easy thermal management are required. 

RoHS compliant and CE marked, the supplies are safety agency certified and meet the latest regulatory requirements. They fit traditional open frame power supply uses in situations where improved power density and increased power is needed. The benefits in tougher thermal environments suit these products to RF applications, 5G systems, industrial process control, automation/monitoring, modern digital signage and video walls.
