AC Constant Current Power Supply AN77 Series

AC Constant Current Power Supply AN77 Series

    AN77 Series constant current ac power supply. Input: 220V/380V; Output: 0~15V, 0~30V, 45~65Hz, 600VA, 750VA, 1.5kVA, 3kVA, 6kVA, 9kVA, 15kVA, etc.

  The AN77 series intelligent variable frequency power supply adopts digital technology and IGBT intelligent output, pure output wave. The power supply can output constant current AC wave, which can be used for short circuit. It outputs constant large current under the condition of small voltage, which can be used for detection of low-voltage power distribution devices such as air circuit breakers, contactors, and transformers, design and production of transformers and inductance devices. It is an ideal tester for device manufacturers, quality inspection institutes, and certification centers for applications with high current test conditions and low energy waste caused by the consumption of the load.
