LBM Series

The Power Supply Unit (PSU) consists of two independent power modules working in parallel, to ensure a reliable redundancy. It has a 3-phase input for 400 / 480 VAC (line to line) and an output suitable for 110 V battery charging and supplying DC loads. AC-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. The PSU includes DSP, which enables monitoring of electrical parameters (including input voltage of all 3 phases) and controlling the PSU from the system controller. Internal CAN bus is used for command, monitoring and diagnostic information that is supplied to the shelf DSP controller and to the external supervising system. External communication is provided by either CAN or Ethernet communication. The LBM series is a highly versatile battery charger which adapts easily to the different requirements of rolling stock on-board power grids and vehicle control systems. The firmware is programmed according customer required parameters, depending on type of battery, charging characteristic, specific monitoring, controlling and communication requirements.
