AV900 High Power Direct Current Test Bench


AV900 High Power Direct  Current Test Bench


The AV900 High Power Direct Current Test Bench has a high power direct current power supply capable of providing up to 900v of electric power. It can be used to test battery packs and can also behave like a battery pack when you connect it to the electric power system of a vehicle. It works in conjunction with the heavy duty dynamometer test cell to serve as a battery emulator.
