1000KW AC 3 Phase Variable Resistive Dummy Load Bank for Generator
Testing
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
1. Fan protection: Machine could not do load testing before working
power of fan is on.
2. The machine will unload and give alarm when any fan is abnormal
or with insufficient air volume, etc.
3. When control power cable in wrong connections, 3 phase fans can
also work in good conditions.
4. Protection button: there are some protection buttons can be
switched off when false alarm or for special requirements.
Application
1. Manufacturers of standby power generators commonly use load
banks to test and tune newly assembled units
2. 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.
3. During this process, the test engineer calibrates and adjusts
the generator performance to ensure it meets the intended product
specifications and tolerances.
