Absopulse Electronics’ DCW 30R Series of rugged, railway quality DC/DC converter modules delivers 30W output power. The modules meet all relevant railway standards including EN 50155, EN50121-3-2 conducted and radiated EMI, EN 55022 Class B, and EN 61000 immunity. These converters offer nominal input voltage options of 24 V, 48 V, 72 V, 96 V or 110 VDC with wide input ranges (EN 50155). Standard output voltages include 12 V, 24 V, 48 V or 110 V. Other input and output values are available on request. The DCW 30R units operate over a -25°C to +70°C cold-plate temperature range without derating. Cooling is via baseplate to a heat sinking surface and by natural convection. They are housed in compact 94 x 48 x 160 mm vented chassis mount enclosures, and weigh 550g. These modules are ruggedized and conformal coated to ensure immunity to shock, vibration and moisture. The DCW 30R converters are also available in open-frame format. The DCW 30R units have 3 kVDC 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.
