1      adopts touch screen control panel to add the mask button, display information, simple to use convenient.
2     Embedded watt-hour meter high standard power, and as a standard for digital closed loop feedback, voltage, current, frequency, phase and active power, reactive power, apparent power, power factor and so on various parameters can be used as the standard.
3     With multiple protection function: current limiting protection, power protection, voltage protection, short circuit protection, current open power amplifier thermal protection, and other functions.
4     three-phase voltage current loop independent control, each phase voltage and current output parameters can be adjusted separately.
5     Smart gear: within the scope of the instrument allows the output, the user can set arbitrary three-phase voltage current gear their rated voltage, current, voltage and current of the sites, the fineness of adjustment of nominal gear is set by the user reference, easy operation.
test voltage, current, phase, rich, easy to operation.

1.1 Output power:
      voltage: 10-456 v voltage (internal gear 57.7, 100, 220, 100 v), the maximum output power 20 va.

1.3 Commonly used output control sites 
Voltage test: 80%, 90%, 100%, 110%, 100%.
Current sites: 1%, 5%, 10%, 20%, 50%, 100%, 50% and 400%.
Phase sites: 0.5 L and 0.8 L, 1.0, 0.8 C and 0.8 C.
Three phase voltage and current amplitude can be regulated respectively, adjust fineness: 10%, 1%, 0.1%, 1%; The adjusting range is the largest to 125%.
Three phase voltage, phase current, power factor can also be split phase adjustment, adjust the fineness of 10 ° respectively, 1 ° and 0.1 ° and 0.01 °.
UB, UC respectively for UA phase can also regulate respectively.
Frequency of adjustment is three-phase voltage and current adjustment, adjust the fineness of 5 hz, respectively
1 Hz, 0.1 Hz, 0.1 Hz.
1.4 power supply 
Single-phase AC 180-265 - v, 50/60 hz.
