XP Power ECH450 450W Open Frame & Enclosed Power Supplies

XP Power ECH450 450W Open Frame and Enclosed Power Supplies are packaged in an ultra-compact footprint of 5.0" x 3.0" and approved for medical and ITE applications. The ECH450 power supplies provide up to 450W force-cooled and 250W convection-cooled, allowing high power densities of 20W/in3. A 12V/600mA fan supply is included to facilitate system cooling, along with a 5V/1A standby output. The power supply contains two fuses and low leakage currents, which are ideal for medical applications. It is safety-approved to operate at a +70° ambient temperature.

The ECH450 devices from XP Power are designed to minimize no-load power consumption and maximize efficiency to meet environmental legislation and medical and ITE standards. EN55011/32 level B conducted emissions allow the ECH450 power supplies to be used in a vast range of applications.
