Datasheet

UCH600 series 

## 600W **Convection cooled** 

**AC-DC power supplies** 

Approved for medical and ITE applications, this range of convection cooled single output AC/DC power supplies are packaged in an ultra compact footprint of just 203.2 x 127.0 mm. The UCH600 provides up to 600W convection-cooled leading to very high power density of 9.5W/in[3] . A 12V/0.6A fan supply is included in the design to faciliate system cooling, if required, along with 5V/1A standby output. The power supply contains two fuses and low leakage currents as required by medical device applications. 

The low profile and safety approvals covering ITE and medical standards along with conducted emissions to EN55011/32 level B allow the versatile UCH600 series to be used in a vast range of applications. 

## **Features** 

- f 600W convection cooled 

- f 203.2 x 127.0 x 40.0 mm U channel

## **Thermal consideration** 

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|
|**T3 coil**|110°C|
|**L4 coil**|120°C|
|**Q5 body**|120°C|
|**C5**|105°C|
|**C37**|105°C|



## **Service life** 

The estimated service life of the UCH600 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 with in the product when installed by the end application,. The graph below expresses the estimated lifetime of a given component temperature and assumes continuous operation at this temperature.
