MIM 50R Series DC/DC converters
Absopulse Electronics is offering the MIM 50R Series compact DC/DC converter modules targeted at railway applications.
Designed for powering video surveillance equipment on trains, these modules are also suitable for a wide range of mobile environments.
These 50W units are housed in compact 66mm x 38mm x 163mm vented enclosures, weigh 400g and are designed to be chassis mounted.
They operate over a -40C to 70C cold-plate temperature range without derating.
Cooling is via baseplate to a heat-sinking surface and by natural convection.
Nominal input voltages are 24V, 48V, 72V, 96V or 110V DC with wide (EN 50155) input ranges; the units deliver single outputs of 12V or 24V DC.
Other input and output voltages are available on request.
The MIM 50R series meet relevant railway standards including EN 50155, EN50121-3-2 conducted and radiated EMI, EN 55022 Class B, and EN 61000 immunity.
These modules are conformal coated for immunity to shock, vibration and moisture.
They have 3kV DC input to output isolation, inrush current limiting and reverse polarity protection at the input.
Over-voltage, over-current, short-circuit and thermal protection are standard.
