PSUs designed to minimise no-load power consumption and maximise efficiency

Designed to minimise no-load power consumption and maximise efficiency to help designs meet the latest environmental legislation, XP Power's ECP225-A PSU series PSUs are now available from Farnell element14. The single-output AC/DC power supplies are approved for medical and ITE applications and offer an ultra low-profile of one-inch high with a footprint of just 3in by 5in. The ECP225-A provides up to 225W force-cooled or 150W convection-cooled leading to very high power densities of 15 W/in3 or 10W/in3 respectively. A 5V, 2A standby output and a 12V, 500mA fan supply are included in the design. The power supply contains two fuses and low leakage currents as required by medical applications and is safety approved to operate in a 70C ambient. No-load input power is less than 0.5W. The low profile and safety approvals covering ITE and medical standards, together with efficiency up to 94% and conducted emissions conforming to EN55011/22 level B, allow the ECP225-A series to be used in a vast range of applications, says the company.
