1.The standard output of 4 phases of voltage and 3 phases of currentIt could combine various type of current or voltage conveniently and has diversity type of protective experiment. Every phase of voltage output is 120V, and the total of the parallel current is 120A. The fourth phase voltage Ux has many functions and it can be set to be 4 type of every three voltages or synchronism checking voltage, or output any value of voltage.

2.Strong function of softwareIt can complete all kinds of large complex check work requiring for high degree automation, such as three phase differential test, auxiliary power supply for fast cutting and automatic input test, line protection by synchronism checking voltage reclosing and so on. and it can easily test and scanning all kinds of protection setting for fault playback, storage real-time test data, display vector chart, online print reports, etc.

3.The amount of switch quantity contacts is rich7 road contact input and 2 couples of empty output contact. The input contact is compatible for both empty contact and 0 ~ 250 v contact, and it has intelligent automatic recognition. Input and output contact can be expanded based on the user’s need.
4.Large LCD screenThe device adopts large and high resolution radio graphics LCD screen with 320 x 240 lattices, and the whole operation process are set on the screen, whose operation interface and test results are both show in English, intuitional and clear.
5.Self-protectionUse reasonable design of the heat dissipation structure, has various reliable and perfect protection and power soft start, along with fault self-diagnosis and locking function.
6.Independent DC power outputThe device is equipped with a way of 110v DC and 220v DC special adjustable power output.
7.Cost-effectiveIt is an interdisciplinary design production, integrating many advanced scientific and technological achievements of many areas. More important, its large tester performance, and small tester price, distinguishes it as a very cost-effective machine.
