200W Railway DC/DC Converters suitable installation on vehicles chassis or machine chassis.

Pure Convection cooling:
· no fans required
· no installation on a heat-sinking surface required
Ideal for curved, uneven or thermally non-conductive surfaces

ABSOPULSE Electronics BAP 236RTH Series railway quality dc/dc converters employ high frequency power conversion topology to generate up to 200W output power. They have generous design headroom and are rated for operation over a -20°C to +50°C temperature range for full specification. Cooling is by heat-sink fins on the top of the units – neither fans nor attachment to a heat-sinking surface are required. The converters can be installed on curved, uneven and non-conductive surfaces, and are ideal for installation on locomotive chassis.

The BAP 236RTH converters comply with all relevant railway standards including EN50155, EN50121-3-2 conducted and radiated EMI, EN55022 Class B, EN61000-4-2, EN61000-4-3, EN61000-4-4 and EN61000-4-6 standards. An industrial grade version that complies with EN/UL60950-1 and equivalent safety standards is also available.

Nominal input voltages include 24Vdc, 36Vdc, 48Vdc, 72Vdc, 96Vdc or 110Vdc with EN50155 input ranges. The converters deliver any customer specified output between 12Vdc and 125Vdc. Other input/output configurations 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. A green LED can be installed to indicate an output ″ON″ condition. An optional output fail alarm (Form C) can be installed.

The units are housed in compact, ruggedly constructed 114 x 114 x 261mm chassis-mount enclosures. They are ruggedized and all printed circuits are conformal coated, providing immunity to shock, vibration (IEC 61373 Categories 1 A&B) and moisture.

Protection features include 3000Vdc input/output isolation, reverse polarity protection, current limiting and overvoltage protection.
