1. Load Testing: It can load any power within the rated value, measure and display the steady-state three-phase voltage, three-phase current, active power, reactive power, apparent power, power factor, frequency, operating time and other parameters of the tested equipment.
2. Control mode selection: you can choose the local or intelligent mode to control the load.
3. Local Control: There is local control panel with several power steps; user can load/unload by button.
4. Intelligent Control: Through data processing software in PC, user can make automatic load, to display, record and manage the testing data, to form curves, tables, also to print them.
5. Control Pattern Interlock, there is control pattern switch, when choose one control pattern, operation of other pattern is invalid, avoid the clash.
6. Load/unload with One Key: Whether manual control, remote control or software control, user can preset the power, then press load master button. Load bank loaded according to preset power to avoid load fluctuation during the power changing.
7. Local Meter Display Data: Three-phase voltage, three-phase voltage, active power, reactive power, apparent power, power factor and frequency parameters can be displayed through the local measuring instrument.
8. DC display data: The battery voltage (meeting the DC60V range) and current (meeting the 100A range) can be monitored through the screen.
9. System charging and discharging control logic: The load system has charging and discharging control for the battery pack, with a charging inverter (bidirectional) and battery pack user provided.
Protection:Emergency Stop; Over voltage Protection; Short Circuit Protection; Overheating Protection; Fan Interlock Protection; Protection Buttons; Chassis Grounded Protection
