Plastic Housing And 500Kw Load Bank 3 Phase For Backup Power Supply
Generator
Product Description
Automatic AC load bank main used to test the capability and aging
degree for high-power ups on-line, inverter, switch power and
diesel generator set for electric power, telecom department and
manufacturer. It can ensure the reliability of constant power
charge that adopts uniformly stepped power input, energy
consumption work model and forced air-cooling model. It is of high
power density, no red hot phenomenon and automatic protection
function overheated. It can’t be overheated and broken when the
fans stop working. The complete machine can be operated simply and
maintain convenient that adopts module design. It can test voltage
and current according to client’s request, and provide scientific
test measures for high-power AC equipment.

Product Advantage
Communication type: through RS232, RS485
Load mode: manual load or automatic load.
Manual load: input power and power factor.
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.
Application
Manufacturers of standby power generators commonly use load banks to test and tune newly assembled units. When the generator has been set up in a test cell within the factory, a test engineer uses the load bank to apply a discrete, selectable electrical load to the generator and measure the response stability and endurance. During this process, the test engineer calibrates and adjusts the generator performance to ensure it meets the intended product specifications and tolerances.
