It can calibrate various relays (such as current, voltage, inverse time limit, power direction, impedance, differential, low cycle, synchronous, frequency, DC, intermediate, time, etc.) and microcomputer protection, and simulate various complex instantaneous and conversion faults for whole group testing.

1. Flexible combination of voltage and current output: With standard 4-phase voltage and 3-phase current output, it can easily perform various combination outputs for various types of protection tests. Each phase voltage can output 120V, and the current of the third phase can output 120A. The fourth phase voltage Ux is a multifunctional voltage item, which can be set as four types of 3U0 or detected for synchronous voltage, or output for one of the voltage values.
 
2. Convenient standalone operation: The device panel is equipped with a trackball mouse, optimized keyboard, and a large screen TFT LCD display, with built-in Chinese Windows platform operating software. Ready to use upon startup, easy and fast to operate.
 
3. Dual operation mode: In addition to standalone operation, the device can also be connected to an external laptop or desktop computer for operation. The two modes have the same functions, providing a truly complete dual operation mode.
 
4. New high fidelity linear power amplifier: The output end has always insisted on using high fidelity and high reliability modular linear power amplifiers instead of switch type power amplifiers, which have good performance. It will not cause high or medium frequency interference on the test site, and ensures smooth waveform accuracy from high current to low current.
