DC/DC power modsABSOPULSE Electronics′ BAP 3K-CR2U/19-3 Series modular, rack-mount DC/DC power conversion system delivers 3 kW or 2 kW with N+1 redundancy. The series is suitable for power utilities, industrial control and telecommunication applications. The BAP 3K-CR2U/19-3 is built with three heavy-duty 1-kW BAP 65F DC/DC modules assembled on a 2U x 19″ rack-mount cradle. The cradle is constructed with high-grade stainless steel and mechanical features that allow for easy insertion of the converter modules. Each converter is equipped with connectors that allow hot-pluggability and enable the insertion or removal of modules without powering down the system. No motherboard is required. Each 1kW module accepts a nominal input of 48 VDC, 72 VDC, 110 VDC, 125 VDC or 250 VDC and is available in several output configurations including 24 V/40 A, 48 V/20 A or 125 VDC/8 A. 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 built-in fan which provides sufficient airflow for operation at 0°C to 50°C temperature range without de-rating.

The converter modules typically deliver efficiencies of 90 percent at full load. Output regulation is ±1.5 percent combined across all input line and load conditions. Protection features include 2250 VDC input to output isolation, output current limiting with short-circuit protection and thermal shutdown with self-resetting. The modules comply with EN/UL60950-1 and equivalent industrial safety standards.
