Description

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.
Features
Low-voltage, high-current AC output to meet the test requirements of relevant regulations;
Output frequency of 45~65Hz, suitable for the test requirements of different grids and devices;
Adjust current and frequency in output state;
Measurement: voltage, current, frequency, active power;
Power-off memory and shortcut keys;
Key lock, humanization design to prevent mis-operation;
Standard RS232 port, optional RS485 port or remote control port.
Custom of current source of any voltage level and current.
Applications
Replace traditional voltage/current regulation, precise control, convenient operation
