750VDC input, railway quality DC/DC converters deliver 3kW
The HVI 3KR-3U4 series of high input voltage, railway quality DC/DC converters deliver up to 3kW output power. The units accept 750VDC input (525V to 975Vdc range), the traction voltage required for mass transit vehicles and mining locomotives. Output voltages include 24, 36, 48V or 110VDC. The series is designed to meet EN50155 for electronic equipment used on railway rolling stock.
The units are filtered on the input and output and comply with EN50121-3-2. They also meet the EN61000 standards for ESD, RF Immunity and Fast Transients. Electronic protection also includes 4300VDC input to output isolation, reverse polarity protection, overload protection, thermal protection and current limiting.
The HVI 3KR-3U4 converters are built with three internal power modules operating parallel via redundancy diodes. This construction provides internal redundancy: if one internal module fails, the unit will continue to function as a 2kW redundant power supply. The HVI 3KR-3U4 units are heavily ruggedised for immunity to shock and vibration. The internal boards are conformal coated for protection from moisutre and airborne contaminants. The converters are fan cooled and rated for operation over a -25 to 55°C temperature range for full specification without derating.
