RDH300 Series

300W half brick baseplate cooled 72 & 110VDC input DC-DC converters for railway applications

Designed for railway applications, the RDH300 series converters comply with EN50155 when combined with the recommended filter components and with EN50121-3-2 railway standards for electronic equipment used on traction & rolling stock.

They are housed in a baseplate cooled ½ brick package. The 43 to 160VDC input range is suitable for 72  & 110VDC railway traction batteries. The modules are fully protected against input UVLO (under voltage lock out), output short circuit, output over voltage and over temperature conditions.

These devices are typically used on traction & rolling stock to power: Train warning & protection systems; Door control; Communication systems; Video surveillance; Access & ticketing machines; Drive controls; Power controls; Passenger information systems; Internal & external lighting.
