DC/DC Converters with 14W for Railway Applications

MTM Power’s PMGS/PCMGS14 series DC/DC converters have been developed for low-range power railway and transport applications.

The devices operate at a nominal input voltage of 72VDC or 110VDC and supply an output voltage of 24VDC (12VDC and 48VDC on request) with a high efficiency of
≥90 %. The PMGS/PCMGS14 are available with an input reverse polarity protection by a series diode and are continuous short circuit protected.

The converters operate at an ambient temperature range of –25°C to 70°C (EN 50155, class T3), fulfill the safety standards according to EN50155, EN50124-1 and meet the EMC requirements according to EN50121-3-2. The converters are designed to withstand interruptions of the supply voltage up to 10ms and thus, comply with class S2 according to EN50155.

Depending on the application, they can be used for print (PMGS) or chassis mounting (PCMGS). Optionally, they are available for DIN rail mounting. Depending on the model, the dimensions are 76mm x 50.7mm x 22.7mm (PMGS) or 110mm x 50.8mm x 23mm (PCMGS).

The vacuum encapsulated converters are maintenance-free, prepared for the use in devices with Protection Class II. They show a mechanically and electrically rugged design using SMD technology and undergo an automatic piece-by-piece test.
