The device comes with an internal ballast switch. The device operates on 50 Hz/60 Hz frequency. At 45 ᵒC, it has a rated current of 23 A. The device has a 16 KVA rated power at the same temperature. There is a power derating at the rate of 0.62 W/K between 45 ᵒC and 55 ᵒC temperature. This power supply has maximum one-time braking energy of 6500 Ws and its maximum continuous braking power is 400 W.

The VMA 20KB 001-D is 100 mm wide and weighs only 15 kg. Its maximum power loss in the switch cabinet is limited to 220 W. For standard operations, the device requires only 1 A current from a 24 V power supply. No backplane module is required for the system’s installation. This power supply module comes with a comprehensive diagnostics setup. Warnings are displayed in case of excessive heat sink temperature, ballast switch overload, and when the VM power limit is reached. Undervoltage and overvoltage warnings are also displayed if the device has a DC link voltage below 400 V or more than 800 V. Similarly module over temperature and ambient overtemperature warnings are also displayed. The VMA 20KB 001-D can be shipped to the address of your choice with a one-year warranty period from Wake Industrial.
