Introduction
Dummy 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.
Applications
The unit is designed in mobile for easy use during generator load testing, electrical and marine load testing.
Use low heat created heating element. In order to minimize the heating element to create so much heat, we design the higher voltage for heating element than what is rated voltage to which the total weight is sacrifice. However, this unit can be used continuously even inside assembly plant because the said heating element is U type or in line element with cooling fins.
