AC-DC Power Supplies
The UCP225 series is designed to minimize the no load power consumption and maximize efficiency
to facilitate equipment design to meet the latest environmental legislation. Approved for medical and
ITE applications, this range of single output AC/DC power supplies are packaged in an ultra-low
profile 1.18” height with a foot print of just 3.12” by 5.0”. The UCP225 provides up to 225 W force-
Dimensions:
UCP225:
5.00 x 3.12 x 1.18” (127.0 x 79.2 x 29.2 mm)
cooled or 150 W convection-cooled leading to very high power densities of 12.2 W/in
3
or 8.1 W/in
3
respectively. A 12 V, 500 mA fan supply is
included in the design which can also be delivered with an optional 5 V/2 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 UCP225 series to be used in a
vast range of applications.
