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.
Application
Load Banks are used with Engine Generators, Battery Systems, UPS
Systems, Inverters, Ground Power Units, Auxiliary Power Units,
Aircraft Power Generators, Wind Generators, and Hydro Generators.
