Absopulse Announces 1kW, Industrial Quality DC-DC Converter with Convection Cooling
Absopulse Electronics announced the BAP 1K-U7712 Series of dc-dc converters that generate up to 1kW output power with convection cooling – no fans or forced air are required. Housed in a compact, ruggedly constructed 7 x 7 x 12" chassis-mount enclosure, these converters are suitable for demanding industrial applications including factory automation systems, industrial control equipment, production machinery and mining equipment. They comply with EN/UL 60950 and equivalent industrial safety standards. A railway grade version that meets EN 50155 is also available.
The 1kW converters contain two internal modules, each capable of generating 500W (minimum). 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 connected in parallel 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 EMI requirements of EN 55022 Class A. Efficiency is 85% (minimum), 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.
