Absopulse Electronics has introduced the PDC 400, a recent addition to its line of rugged, DC/DC converters. Designed for operation in extreme environments, it is well suited to transportation, industrial, oil & gas, mining and utility environments. The unit is fully encapsulated in a thermally conductive MIL-spec. silicon rubber compound ensures immunity to high levels of shock, vibration and moisture. The PDC 400 is designed to meet IEC 61373 Categories 1 A & B shock and vibration standards. It is also designed for continuous operation in a -40°C to 70°C temperature range with installed on an appropriate size heat-sinking surface. Versions to meet EN 50155 railway specifications and customized designs are also available.

This 400W professional converter utilizes field-proven push-pull topology to deliver 12V, 24V, 36V or 48Vdc. It can be operated from 24V, 36V or 48V or 125Vdc supply voltages. Other input and output options are available on request.

The PDC 400 is filtered to meet EN 55022 Class B EMI and is designed to meet EN 60950 and related standards. The unit features inrush current limiting and surge protection on the input. Output protection includes current limiting with short-circuit protection and thermal shutdown with self-resetting. Combined line and load regulation are ±1% from no load to full load and efficiency is a minimum of 80%.
