Strong demand for REGATRON's high-current, low-voltage DC power supplies. Up to 2028 A output current per 10 U device.

This picture shows the rear view of two high-current, low-voltage, bidirectional regenerative G5 DC power supplies. Each unit has the following nominal values: 18 kW / 80 VDC / 676 A.

Thanks to the high autoranging factor of 3, the new G5 high-current DC power supplies are also well suited for 12, 24 and 48 VDC applications. The adjacent graph shows the characteristic output diagram of a 54 kW / 80 VDC G5 power supply.

The adjoining graph gives an application example. The test sequence shown is taken from the VDA320 standard and relates to the testing of electric vehicle components supplied by a 48 V on-board power system. The sequence shown is titled E48-02 Transient Overvoltage and is described in the standard as follows: "Transient overvoltages can occur in the 48 V power supply. This test simulates such overvoltages." The most common standards, which are largely covered by REGATRON's high-current, low-voltage G5 DC power supplies, are: LV124, LV148, VDA320, ISO16750-2, ISO21498-2. Other proprietary standards of the worldwide car manufacturers are also covered.
