Automatic AC load bank is mainly 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 adopted 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. Adopted module design, the complete machine can be operated simply and maintain convenient. It can test voltage and current according to client's request, and provide scientific test measures for high-power AC equipment.
Main functions
Users can set adjustable discharge power according to capability parameter and test request.
Discharge time can be set: load can be closed time out.
Voltage and current value can be displayed with number table.
Adopted new power consumption component, the complete machine has resistance breaking automatic overheated function.
AC load bank has kinds of specifications and series, and include resistance, inductive and capacitive load.
It has machine combination function.
Function options
Automatic AC load bank: Power, voltage and current test value can be displayed with digital table
Intelligent AC load bank (LED): multi-function number special meter of 0.5 step can be test and display: AC voltage, current, active power, power factor and frequency. It can communicate with PC via RS485 interface.
Intelligent AC load bank (LCD): Special LCD meter display: AC voltage, current, active power, power factor and voltage frequency. It is of the harmonic analysis function of 1-40 times, and can communicate with PC via RS485 interface.
