1kW, Industrial Quality DC/DC Converter with convection cooling - no fans or forced air required

The ABSOPULSE Electronics BAP 1K-U7712 series dc/dc converters generate up to 1kW output power with convection cooling. Housed in a compact, ruggedly constructed 173 x 173 x 314 mm chassis-mount enclosure, these converters are suitable for demanding industrial applications where fans or forced air are not feasible. The series complies with EN/UL 60950 and equivalent industrial safety standards. A railway grade version that meets EN 50155 is also available.

The 1kW converters are comprised of two internal modules, each capable of generating a minimum of 500W. The design has inherent redundancy which ensures that the unit remains functional at 500W if one internal module fails. A dual output version with two independent, fully regulated outputs of 500W each is also possible. Several units may be paralleled if output power higher than 1kW is required.

The BAP 1K-U7712 units operate from inputs of 48V, 72V, 110V, 125V or 250Vdc ( 15%) and provide tightly regulated outputs of 24V, 48V, 110V or 125Vdc. Other input/output values are available on request.

The converters meet EN 55022 Class A EMI standards with wide margins. Efficiency is 85% (minimum) at full load, depending on the input/output configuration. Protection features include 2250Vdc input/output isolation, overload, over-voltage and short circuit protection with thermal shutdown and self-resetting. A module fail alarm (Form C) and remote shutdown are available as options. Other options include conformal coating, heavy ruggedizing and extended temperature ranges. Generous design headroom and the use of designed-in components with established reliability contribute to high MTBF and ultimately, low life cycle costs.

For the BAP 1K-U7712 specifications, please see datasheet above (right).

Absopulse offers an extensive range of dc/dc converters designed for operation in harsh environments. These rugged designs can be modified to meet your electrical and mechanical requirements. We also provide fully-custom solutions with short delivery times and low set-up costs.

We also design and manufacture AC/DC power supplies, rectifiers and battery chargers, sine-wave inverters, phase and frequency converters, DC-input dimmable back-light inverters for LCD displays, DC-output UPS systems and complete power systems in 19" and 23" racks.
