3kW, Compact DC/DC converter modules target Railway environments

This converter meets all relevant railway standards including EN50155 for electronic equipment used on railway rolling stock. It also has input and output filtering in compliance with EN55022 and EN50121-3-2 conducted and radiated EMI standards.

The BAP 3KR unit has four internal modules, which also provide inherent redundancy; the failure of one module would result in only a minor loss in total output power. The unit has 3kVdc input to output isolation, inrush current limiting and reverse polarity protection at the input. Over-voltage, rectangular current limiting with short circuit and thermal protection are standard. Optional output fail alarm (Form C), indicators and control input are available.

This compact unit measures 244 x 132 x 407 mm and weighs 8 kg. Built-in fans provide sufficient airflow for operation up to 55ºC without de-rating. It is fully ruggedized and conformal coated to ensure immunity to shock, vibration and moisture and meets IEC 61373 Categories 1 A & B shock and vibration standards.

For detailed specifications on the BAP 3KR as well as the BAP 1K5R and BAP 2KR please see datasheets above (right).

Absopulse also offers an extensive range of encapsulated (potted) and convection cooled converters for railway and other extreme environments.
