Automatic load: 

User can preset power and length of operation time for several load 

periods.   

Parallel testing: 

When load banks are used in parallel users can control the parallel test 

using the software. User can display and record parameters of each load bank and 

system parameters.   

Real-time parameter: 

Through the software you can display voltage, current, power, 

power factor, frequency, and time.   

Security monitoring and control: 

Monitor working state of the load bank by watching 

software light. When there is abnormal occurrence, the load will stop and protect from 

damage. Stop reason will be shown.   

Data collection interval: 

The minimum data storage interval is two seconds.   

Data save and query: 

Test data is saved in the software which can be accessed in the 

testing data history.   

Graphical display: 

View and print real-time or historical testing data curves and graphs 

as follows:   

1) Graphs of real-time voltage, current, frequency and power   

2) Voltage graph   

3) Current graph   

4) Power graph   

5) Frequency graph   

6) Power factor graph   

Data format: 

All curves and graphs can be outputted as ‘.doc’ format. Testing data can be 

outputted as ‘.xls’ format and can be printed. 

 
2.7 Protection 

 

Emergency stop: 

User can press the Emergency Stop switch in the panel and the load 

bank will stop supplying current. When locked in this state the load/unload button cannot 

be used. 

Overvoltage protection: 

When input voltage is over the safe value, the load automatically 

stops and gives an alarm.   

Short circuit protection: 

When short circuit occurs, fuses in the load bank insure load 

stops automatically.
