The UCP180 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 1.16” height with a foot print of just 2.5” by 4.3”. The UCP180 provides up to 180 W force-cooled or 120 W convection-cooled leading to very high power densities of 14.2 W/in[3] or 9.4 W/in[3] respectively. A 12 V, 500 mA fan supply is 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 70 °C ambient. The low profile and safety approvals covering ITE and medical standards along with conducted emissions to EN55011/32 level B enable the versatile UCP180 series to be suitable for a vast range of applications.

## Thermal Considerations ~~Me~~ 

In order to ensure safe operation of the PSU in the end-use equipment, the temperature of the components listed in the table below must not be exceeded. Temperature should be monitored using K type thermocouples placed on the hottest part of the component (out of direct air flow). See Mechanical Details for component locations. 

|Temperature Measurements(At Maximum Ambient)|Temperature Measurements(At Maximum Ambient)|
|---|---|
|Component|Max Temperature °C|
|TR1 Coil|110°C|
|L4 Coil|120°C|
|C2|105°C|
|C52|105°C|



## Service Life ~~Me~~ 

The estimated service life of the UCP180 is determined by the cooling arrangements and load conditions experienced in the end application. Due to the uncertain nature of the end application this estimated service life is based on the actual measured temperature of a key capacitor within the product when installed in the end application, 

The graph below expresses the estimated lifetime of a given component temperature and assumes continuous operation at this temperature.
