Absopulse Introduces 25W, Low Profile Encapsulated DC-DC Converter for Railway & Other Extreme Environments

March 31, 2010 by Jeff Shepard

Absopulse Electronics introduced the FLP 09R, a recent addition to its dc-dc converter series designed for low power railway requirements. With a height of just 20mm, this compact 25W unit is suitable for applications with stringent space restrictions. Originally designed for an on-board railway application, this converter is also suitable for operation in numerous extreme environments.

The FLP 09R is fully encapsulated with a thermally conductive MIL-grade silicon rubber compound with a UL94V-0 flammability rating, and operates at full specification over a -40°C to 70°C cold plate temperature range.

Nominal input voltages are 24, 36, 48, 72, 96 or 110Vdc with wide input ranges; the unit delivers single outputs of 3.3, 5, 12, 24 or 48Vdc. Other input and output voltages are available on request.

The FLP 09R meets EN 50155 for electronic equipment used on railway rolling stock as well as EN 55022 Class B and EN50121-3-2 conducted and radiated EMI standards. It also meets IEC 61373 Categories 1 A & B and Category 2 shock and vibration standards. The unit has 3kVdc input to output isolation, inrush current limiting and reverse polarity protection at the input. Over-voltage protection, over-current, short circuit and thermal protection are standard.

The FLP 09R is priced in the US$200 range at low quantities.
