Measuring Control Function

--Load testing: Load power that not beyond the rated power, testing and display stable state 3 phases voltage, current, active power, frequency, working time, etc of generator sets.

--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.

--Control Pattern: user can choose local control and intelligent control.

--Local Control: There is local control panel with several power steps; user can load/unload by button.

--Intelligent Control: Through data processing software in PC, user can make automatic load, display, record and manage the testing data, form curves, tables, also print is available.

--Control Pattern interlock: There is control pattern switch, when choose one control pattern, operation of other pattern is invalid, avoid the clash.

--Local meter display data: Local meter can display 3 phases voltage, current, active power, frequency and so on.

Software Function

--Communication pattern: Intelligent control use photoelectric isolated RS485 interface connect to PC, with great anti-interference performance to make system control stable. Also user can use USB or RS232 through converter.  

--Load pattern: Manual Load or Automatic Load.

--Manual Load: Input power, system will load according to preset power.

--Automatic load: User can preset power and length of working time of several load periods, as per 0%→25%→50%→75%→100% or 110% to make testing.

--Real-time parameter: Through software to display voltage, current, power, power factor, frequency and time, etc.

--Data Collection Interval: the minimum data resolving time is 2s.

--Security monitoring and control: Monitor working state of the load bank by watching software light, when abnormally stop and protect, it can show the reason.

--Data save and query: All the test data is saved in the software, easy to query in the history testing data.

--Graphical display: Show real-time or history testing data, and support to print curve and graph 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 the curves and graphs can be outputted as".doc"format, testing data can be outputted as ".xls" format, and can be printed.

Protection

--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.  

--Overvoltage Protection: When input voltage is over the safe value, it can unload automatically and give an alarm.

--Short circuit Protection: When short circuit, fuses in the load bank can insure to unload automatically.

--Overheating Protection: When temperature is over the safe value, it can unload automatically and give an alarm.

--Fan interlock Protection: Load bank cannot add any load when working power of fan is off.

--Protection Buttons: There are buttons for some protection, when misinformation occurs or user has special needs, user can temporarily turn off the corresponding protection function.

--Chassis Ground Protection: In order to avoid the danger of electric shock when operating, the load bank is equipped with special ground protection terminal.
