High Performance 
? Low Distortion Interference, Complete Input/Output Isolation
? The maximum single-phase capacity can reach 15KVA and the three-phase power supply can reach 45KVA.
? Remote voltage feedback function to ensure the consistency of test point voltage value and setting value
? Voltage and current measurements are based on high precision ADC AC sampling and digital real value calculation.
? A single chip computer (D/A circuit) is used to collect voltage and current waveform data directly. 
? contains RS232 or RS485 interface, communicate with computer. Five groups of test groups can be set up on a single machine. Each group can set up 35 different test points (different voltage0~300V, frequency45~500Hz, time 0.1S~999.9H and can do (0~999999) cycle test.
? Built-in soft start device can easily start motor, compressor and other high starting current load
? The central processing unit is used to control the opening and closing of logic circuits.
? In-machine temperature and humidity detection, intelligent exhaust dehumidification, ensure the normal use of power supply

Humanized design
? Ultra-large 7-inch touch screen displays parameters: voltage, frequency, power, power factor, current, peak current, temperature, electric quantity, time, phase angle, impedance value and real-time curve of voltage and current.
? Power supply multi-point real-time sensor monitoring, running normal code and fault code screen display, fully control the power supply status.
? The parameter calibration is accomplished by open software, and different from other power sources, the potentiometer and adjustable resistance are also adjusted in the circuit.
? Wide range of voltage and frequency regulation, digital key input, independent display of three-phase voltage and line voltage
? Digital password lock, test data security and prevent important test data from being modified by misoperation
