250W DC-DC Converters designed for curved, uneven or thermally non-conductive surfaces on vehicles or machine chassis


Pure Convection cooling. No fans or installation on a heat-sinking surface is required.

The BAP 236TH Series dc/dc converters generate up to 250W output power. Cooling is by heat-sink fins on the top of the units – no fans and no attachment to a heat-sinking surface are required. They can be installed on curved, uneven and non-conductive surfaces, such as plastic, and are ideal for installation on the curved surfaces of vehicles and machine chassis.

The converters have generous design headroom and are rated for operation over a -20°C to +50°C 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) and provide tightly regulated outputs of 24V, 48V or 125Vdc. Other inputs/outputs are available on request. 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 113 x 115 x 261 mm chassis-mount enclosures.

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

ABSOPULSE Electronics is an original equipment manufacturer (OEM). We design and manufacture an extensive range of industrial and railway grade power conversion products in-house, all at reasonable prices.
