Wiper System PSU – HR2320-9RG

CASE STUDY
"We want a converter to power our wiper systems"

Request

Here at RELEC we fully understand that it is not just the input supply which can damage a power supply, but also the output load. We were asked to supply a converter which could be used to power wiper systems on
trains. As well as finding a solution for 24V and 110V train batteries we had to find a product which could withstand the back emfs and start up currents of the wiper motors.

  • HR Series

    Input: 12 to 168Vdc
    Outputs: 12 to 96V
    Power: 288 Watt
    Tamb: -40 to +70°C
    Dims: 168 x 111 x 80mm (3U x 16TE)
    UL / CE EN60950 Approved
    5 Year Warranty

Refine

Key to sourcing a reliable solution for the project was identifying a PSU with a square
current limit characteristic. This would ensure that the motors would start correctly every time. The HR2320-9RG fully meets the current railway standards and is a stock item for us here at RELEC and can operate from all traction supply voltages.

  • HP series

    Input: 12.5 to 154Vdc
    Outputs: 5 to 96V
    Power: 150 Watt
    Tamb: -40 to +70°C
    Dims: 164 x 111 x 20mm (3U x 4TE)
    UL / CE EN60950 Approved
    5 year warranty
