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.
• 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. The one-to-one driving method is beneficial to disperse heat dissipation of power components and redundant design in structure.
• Inspection of temperature and humidity in the machine, intelligent ventilation and are faction in wet weather to ensure the normal use of power supply

Humanized design
• LCD Display parameters: voltage, current, power, power factor, frequency, peak current and time
• LED Displaying voltage, current, frequency, power （ power factor）
• A group of test groups can execute 35 test points (different voltage0~300V, frequency45~500Hz, time 0.1S-999.9H settings), and can do continuous cycle (0~99999999 times) testing. 
• 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
