Good quality Portable Load Bank for sales
We are highly appreciating the neat finishing and will organized system. To be honest with you,as I am in power generation since more than 30 years, your load bank is the best I ever see.It is perfect. Thank you and thank everybody who participated in design manufacturind packaging and handling these banks.

Main features

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.

Parallel testing: when several load bank work in parallel, use can make parallel testing via software, can display, record parameters of every load bank and whole system parameter of parallel operation.

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

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.
