1) User could load any power within rated power, can test stable state
three-phase voltage, current, active power, reactive power,
apparent power, power factor, frequency, running time of generating
set.
2) Whether load/unload by manual control panel, remote control or by
PC software control, user can pre-set the power then press the
master load button.
3) Control mode: user can choose local manual control, remote control
or Intelligent control(PC control)
3.1 Local manual control: there is local control panel in load
bank, with multi load steps, min load steps 1kW, controlled by
buttons.
3.2 Remote control: remote controller connected the load bank with
control cable.(optional)
3.3 Intelligent control: user can control load bank by data
processing software of PC to make automatic load/unload, display,
record and manager the test data, form curve, graph and can be
printed.
4) Control mode interlock: there is switch in control panel to choose
control mode, other control mode is invalid if user choose one
control mode.
5) With data processing software, could form curve of current, active
power, reactive power, apparent power, power factor, frequency and
can be printed.
6) One-key load/unload: user can load or unload with one key easy to
control.
7) 3 line LED multi-function meter display.
