Triple-output, railway quality DC-DC converters

The three outputs are fully regulated, floating and isolated from each other. A typical output configuration: 5.1Vdc/10A (main), 12Vdc/2A (V2) and 12Vdc/2A (V3). A wide selection of other output configurations is possible. Regulation is better than 1% from no load to full load on all three outputs. The converters accept inputs of 24V, 48V, 72V, 96V or 110Vdc with wide input ranges.

The units meet EN50155 for electronic equipment used on railway rolling stock. They also comply with EN50121-3-2 and EN55022 Class B conducted noise and radiated emissions. Electronic protection includes 3kVdc input to output isolation, inrush current limiting and reverse polarity protection, short circuit protection and individual current limiting on all three outputs.

Natural convection and conduction provides sufficient cooling for operation in -20°C to +55°C temperature range with no derating. The compact units are packaged in robust, aluminum 4.5" x 2.3" x 10.1" enclosures. They are fully ruggedized and conformal coated. The series meets EN61373/IEC61373 shock and vibration standards.

Absopulse Electronics is an Original Equipment Manuacturer (OEM) of an extensive range of railway and industrial grade power conversion solutions designed and built to meet almost any input/output configuration requirements.
