LBC Series - Battery Charger

The shelf consists of a ruggedized Battery Charger, PSU with a 3-phase input for 400 / 480 VAC (line to line) and with an output suitable for 110V battery charging. DC-DC stage to convert the 3-phase input voltage to a bus voltage with battery charging capability. Emphasis is given on high reliability and long life. Two or three parallel independent units inside the shelf with active current sharing are used, which safeguards reliability and partial redundancy of the system. The PSU includes DSP which enables monitoring of electrical parameters (including input voltage of all 3 phases) and controlling the PSU from system controller. Internal RS485 / CAN bus is used for command, monitoring and diagnostic information that is supplied to the shelf controller and to the external supervising system. External communication is provided by either CAN or Ethernet communication.

Specifications

  • 92% typical efficiency
  • Output power up to 12 kW
  • 400 / 480 Vrms 3-phase 50/60 Hz input voltage range (no neutral) with PF > 0.94
  • -25 to 55°C of operating ambient temperature without derating
  • Nominal output voltage for 110V battery (adjustable 80 – 137.5 VDC)

Features

  • Shelf with 2-3 power units, 1 control unit and cable harness
  • Parallel operation with active current sharing
  • CAN bus / Ethernet Interface
  • Designed to meet Railway standards EN 50155, EN 50121-3-2, EN 45545, NFPA 130
