Absopulse Electronics’ PDC 500 is a recent addition to its line of rugged DC/DC converters. This unit is encapsulated in a thermally conductive MIL-spec silicon rubber compound for immunity to shock, vibration and moisture and is suitable for operation in transportation, oil and gas, mining, industrial automation, utility and other extreme environments. It operates in a -40°C to +60°C cold plate temperature range, with extended temperature ranges available on request. The PDC 500 is designed to meet IEC 61373 categories 1 A and B shock and vibration standards.

Absopulse also offers a 500W, encapsulated converter that complies with EN 50155 for electronic equipment used on railway rolling stock. This 500W converter utilizes field-proven push-pull topology to deliver 12VDC, 24VDC, 48VDC or 110VDC and it operates from 24VDC, 48VDC or 125VDC supply voltages. At 125VDC input, the unit can provide up to 600W output power. Other input and output options are available on request.

The converter is filtered to meet EN 55022 Class A EMI with wide margins. It is also designed to meet EN 60950 and related standards. The unit features inrush current limiting and surge, and reverse polarity 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 82%.
