2U Rack-mount Power System with Hot-pluggable 1kW Modules delivers 3kW

The system 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 converter unit is equipped with connectors that allow hot-pluggability, enabling the insertion or removal of modules without powering down the system. No motherboard is required, which contributes to the cost-effectiveness of this design. The BAP 65F 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. 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 1kW modules typically deliver efficiencies 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.

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.
