Measuring Control Function
1.Load testing: load power that not beyond the rated power, testing and display stable state 3 phases voltage, current, active power, reactive power, apparent power, power factor, frequency, working time, etc of generator sets.
2.Load/unload with one key: Whether manual control and software control, user can preset the power, then press load master button. Load bank load according to preset power to avoid load fluctuation during the power changing.
3.Control Pattern: user can choose local control and intelligent control.
4.Local Control: There is local control panel with several power steps, user can load/unload by button.
5.Intelligent Control(automatic 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.
6.Control Pattern interlock: there is control pattern switch, when choose one control pattern, operation of other pattern is invalid, avoid the clash.
7.Local meter display data: local meter can display 3 phases voltage, current, active power, reactive power, apparent power, frequency and so on.
1.Emergency stop: you can press the Emergency Stop switch in the panel, when the load bank is locked in this state, it cannot add any load. 2.Overvoltage protection: when input voltage is over the safe value, it can unload automatically and give an alarm.
3.Short circuit protection: when short circuit, fuses in the load bank can insure to unload automatically.
4.Overheating protection: when temperature is over the safe value, it can unload automatically and give an alarm.
5.Fan interlock protection: load bank cannot add any load when working power of fan is off.
6.Fan phase sequence auto conversion protection: 3 phase fan can operate normally when the control power phase sequence is reversed.
7.Protection switch: Some of the protection functions equip with switch, can shut off it when false alarm or special demand. AC400-20kW
