AC-DC Power Supplies XPPower ECH450 Series 450 Watts Force cooled and convection cooled ratings Medical and ITE approvals Compact 3.0 by 5.0 footprint Suitable for BF applications 5 V standby and remote on/off 12 V fan output -20 C to +70 C operation High efficiency, up to 94% Approved for medical and ITE applications, this range of forced and convection cooled single output AC/DC power supplies are packaged in an ultra compact foot print of just 5.0 by 3.0. Dimensions: ECH450: The ECH450 provides up to 450W force cooled and 250W convection cooled leading to very high 3.00 x 5.00 x 1.42 (76.2 x 127.0 x 36.1 mm) 3 power densities of 20W/in . A 12V, 600 mA fan supply is included in the design to faciliate system ECH450-TF, ECH450-C: cooling, along with 5 V/1 A standby output. The power supply contains two fuses and low leakage 3.41 x 5.00 x 1.97 (86.6 x 127.0 x 50.0 mm) currents as required by medical applications. ECH450-EF: The ECH450 series is designed to minimize the no load power consumption and maximize 3.15 x 5.83 x 1.60 (80.0 x 148.2 x 40.6 mm) efficiency to facilitate equipment design to meet the latest environmental legislation and the low profile and safety approvals covering ITE and medical standards along with conducted emissions to EN55011/32 level B allow the versatile ECH450 series to be used in a vast range of applications.
