Features
Description
The CP2725AC48TEZ-FB Rectifier has an extremely wide programmable output voltage capability and fold-back current
limiting features. High-density front-to-back airflow is designed for minimal space utilization and is highly expandable for
future growth. This custom rectifier incorporates both RS485 and dual-redundant I
2
C communications busses that allow it
to be used in a broad range of applications. Feature set flexibility makes this rectifier an excellent choice for a set of
applications requiring operation over a wide output voltage range.

Contract terms are for supporting all loads inside the load map. The customer will develop a control interface which
maintains the operating voltage and current so as to not exceed the load map.

Units should be able to be plugged in one at a time and guarantee system start up. Units should stay in current limit
for approximately 20 seconds to guarantee restart.
