2U Rack-mount Power System with Hot-replaceable 1kW Modules

2U x 19” stainless steel cradle with 3xBAP-65F hot-replaceable modules

ABSOPULSE Electronics′ BAP 3K-CR2U/19-3 Series modular, rack-mount DC-DC power conversion system delivers 3kW or 2kW with N+1 redundancy. It is built with three heavy-duty 1kW (BAP-65F) power supply 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 BAP-65F modules. Each DC-DC converter unit is equipped with connectors that allow hot-replacement, enabling the insertion or removal of modules without powering down the system. The cradle has no motherboard, which contributes to the cost-effectiveness of this design. The modules can also be used as stand-alone units.

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. A 24Vdc input is available, derated to 750W. 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.

The modules 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°C to 50°C temperature range without de-rating.

The converter modules typically deliver efficiency of 90% at full load. Output regulation is ±1.5% combined across all input line and load conditions. Protection features include 2250Vdc 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.

The series is suitable for operation in power utility, industrial control and telecommunications environments.

ABSOPULSE offers an extensive range of these heavy-duty, modular, power systems which can readily be adapted to customer requirements. We also provide fully-custom solutions with short delivery times and low set-up costs. We would be pleased to discuss the power conversion requirements of your next project.
