FUNCTION:
1.Control mode selection
Control the load by selecting local and intelligent methods.
2.Local control
Through the switches and meters on the local control panel, the manual loading/unloading control of the load box and the viewing of test data are performed.
3.Intelligent control
Control the load through the data management software on the computer, realize automatic loading, display, record and manage the test data, generate various curves and charts, and support printing.
4.Control mode interlocking
The system is equipped with a control mode selection switch. After selecting any control mode, the operations carried out by the other modes are invalid to avoid conflicts caused by multiple operations.
5.One-button loading and unloading
whether manual switch or software control is used, the power value can be set first, and then the total loading switch is activated, and the load will be loaded according to the preset value, so as to avoid the load caused by the power adjustment process. fluctuation.
6.Local instrument display data
The three-phase voltage, three-phase current, active power, reactive power, apparent power, power factor, frequency and other parameters can be displayed through the local measuring instrument.
