LVPS/BC 5000W 480V/3PH-60Hz, 72V/75A

Part # 020-0072-00

LVPS/BC is a 5600 W power supply designed for railway passenger cars. It provides two (2) outputs at a nominal voltage of 71 Vdc (adjustable from 65 to 78 Vdc):

1) Nominally 40 Adc for car load systems.
2) Nominally 35 Adc for car battery charging.

Suitable for transportation, mobile and harsh environment operation.

High reliability power supply and battery charger on rail passenger cars accepting source power from 480 Vac head end power system.

DC link power supply for uninterruptable power supply systems.

Remote controlled and monitored Power Supply for isolated installations (Pipelines, communication cells, etc.)
