The PBR500 series of AC-DC switching power supplies, in a package of just 4 x 7 x 1.7 inches, deliver 450-500 watts of continuous power with forced air cooling or 350-400 watts with convection cooling. The units are constructed on a U-Channel for mechanical support and heat sinking. A cover and fan assembly can be added during manufacturing. They are designed for both ITE/Industrial and medical applications including those needing BF rated insulation with an operation altitude up to 5000 meters. 

Dimensions: PBR500: 7.0 x 4.00 x 1.70” (177.8 x 101.6 x 44.5 mm)

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 below for component locations. 

|Temperature Measurements(At Maximum Ambient)|Temperature Measurements(At Maximum Ambient)|
|---|---|
|Component|Max Temperature °C|
|T1 Coil|120°C|
|L1, LF1, LF2 Coil|120°C|
|EC1|105°C|
|EC8|105°C|



The estimated service life of the PBR500 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 key capacitors within 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.
