AC-DC Power Supplies UCH600 Series 600 Watts Convection cooled Medical and ITE approvals Compact 5.0 by 8.0 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 95% Dimensions: Approved for medical and ITE applications, this range of convection cooled single output UCH600: AC/DC power supplies are packaged in an ultra compact foot print of just 5.0 by 8.0. 8.00 x 5.00 x 1.57 (203.2 x 127.0 x 40.0 mm) The UCH600 provides up to 600 W convection-cooled leading to very high power density 3 of 9.5 W/in . A 12 V/0.6 A fan supply is included in the design to faciliate system cooling, if required, along with 5 V/1 A standby output. The power supply contains two fuses and low leakage currents as required by medical applications and is safety approved to operate in a 70 C ambient. The low profile and safety approvals covering ITE and medical standards along with conducted emissions to EN55011/22 level B allow the versatile UCH600 series to be used in a vast range of applications.
