Absopulse Electronics’ BAP 3K-CR2U/19-3 Series modular, rack-mount dc/dc power conversion system delivers 3kW or 2kW with N+1 redundancy. The series is recommended for power utilities, industrial control and telecommunication applications. The BAP 3K-CR2U/19-3 is built with three heavy-duty 1kW BAP 65F dc/dc modules assembled on a 2U x 19” rack-mount cradle. Each 1kW module accepts a nominal input of 48Vdc, 72Vdc, 110Vdc, 125Vdc or 250Vdc and is available in several output configurations including 24V/40A, 48V/20A or 125Vdc/8A. Customer specified input and output voltages are also available. A built-in redundancy diode allows for parallel connection to increase current available to the load and for N+1 redundant operation. They are each equipped with an output fail alarm with Form C contacts and a diagnostic output ON LED. Each unit has a high quality built-in fan which provides sufficient airflow for operation at 0 degrees Celsius to 50 degrees Celsisus temperature range without de-rating.
