PKB-C series

50-200W Eighth Brick Isolated DC/DC Converter

The PKB-C series is an analog isolated DC/DC converter in an eighth brick format. They offer a V_out range between 1.0-30V and a wide V_in range from 36-75V typically needed in telecom applications.

These converters can deliver up to 200W and have a high efficiency up to 95% typical at 48V_in / 50% load.

The PKB-C series can operate over a temperature range from -40°C up to +125°C and offers an MTBF of up to 3.5 million hours.

Standard features for this model include remote control, output voltage adjust, remote sense, over-voltage protection, over-current protection and over-temperature protection. Modules are available with or without baseplates to facilitate different cooling methods.
