System can do stable test, transient test, and realize functions, such as setting, fluctuation, instant load, and instant unload. The terms and formulas used in test strictly comply with relevant national standard.

Comprehensive Protection Function:

Multiple protection, like over temperature, smoke. When in danger, automatically terminate the test and give alarm to protect safety of personnel and

equipment.

Flexible Control Mode:

Based on different using habit, several control modes as following can be choose, local panel operation, remote box controlling, and intelligent software.

Main Functions

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.
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.
Control mode: user can choose local manual control, remote control or Intelligent control (PC control).

Local manual control: there is local control panel in load bank, with multi load steps, min load steps 1kW, controlled by buttons.
Remote control: remote controller connected to the load bank with control cable (optional).
Intelligent control: user can control load bank by data processing software of PC to make automatic load/unload, display, record, and manage the test data, form curve, graph and can be printed.

Control mode interlock: there is a switch in the control panel to choose control mode, other control mode is invalid if user choose one control mode.
With data processing software, could form curve of current, active power, reactive power, apparent power, power factor, frequency and can be printed.
One-key load/unload: user can load or unload with one key easy to control.
3 line LED multi-function meter display.

Data Processing Software Functions

Communication type: through RS232, RS485 or USB interface.
Load mode: manual load or automatic load.
1. Manual load: input power and power factor.
2. Automatic load: User can set several periods of power and time, and in turn of 0%→25%→50%→75%→100%, etc preset order to make automatic load testing.
Parallel testing: when several load banks are working in parallel, parameters of each load bank can be displayed and recorded, as well as the final parameters of paralleling working.
Real-time parameter: Current, voltage, power, power factor, frequency, time, etc., could be displayed by software.
Safety monitoring: User can know the working conditions of the load bank through software indicating light. When in abnormal stop protection, the software will indicate the reasons for stopping.
Data collection interval: The minimum saving interval is 2 seconds.
Data saving and in query: Testing data could be saved in software, and the user can query it at any time.
Data display: It could display real-time data and historical data; the user can print voltage, current, frequency, power graphs, and charts.
Charts and graphs are output in the format of JPG, while testing data is output in Excel format, and all can be printed.

Protection Features

Emergency Stop: User can press the emergency stop button in the panel to unload immediately when the load bank is abnormal while working.
Over-voltage Protection: Automatic load dump and give alarm when voltage is over safety thresholds.
Over-heat Protection: Automatic load dump and give alarm when temperature is over safety thresholds.
Short Circuit and Insulation Protection: Equipped with a fuse, automatic load dump when current is too large.
Fan Interlock Protection: Machine cannot do load testing before the working power of the fan is on.
Phase Sequence Automatic Conversion Protection: When control power cables are connected incorrectly, the 3-phase fans can still work in good conditions.
Protection Button: There are protection buttons that can be switched off when false alarms occur or for special requirements.
Enclosure Ground Protection: The load bank has a special ground protection terminal to avoid the user being at risk of electric shock hazards.
