DC/DC converters for curved, uneven or thermally con-conductive surfaces

November 02, 2012 // By Julien Happich
The BAP 236TH Series dc/dc converters from Absopulse generate up to 250W output power, with cooling guaranteed by optimally adapted heat-sink fins on top of the units.

The converters can be installed on uneven and non-conductive surfaces, such as plastic and are suitable for installation on the curved surfaces of vehicles or machine chassis. They have generous design headroom and are rated for operation over a -20oC to +50ºC temperature range for full specification. The units comply with EN/UL60950 and equivalent industrial safety standards. A railway grade version which meets EN50155 is also available. The BAP 236TH converters operate from inputs of 24V (21-30V), 48V (42-60V) or 125V (105-145V), equivalent voltage ranges meeting EN50155 and provide tightly regulated outputs of 24V, 48V or 125Vdc.

Other input/output configurations are available on request as well. An optional built-in redundancy diode allows for paralleling and N+1 operation. The redundancy diode also allows for connection to a back-up battery. Efficiency is 85% at full load, depending on the input/output configuration.
The converters are filtered to meet EN55022 Class B conducted and radiated requirements. Protection features include 2250Vdc input/output isolation, overload, over-voltage and short circuit protection with thermal shutdown and self-resetting. An output fail alarm (Form C) is available as an option. Other options include conformal coating, heavy ruggedizing and extended temperature ranges. The units are housed in compact, ruggedly constructed 113x115x261mm chassis-mount enclosures.
