Introduction:
Intelligent 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.
Main functions
1. Users can set adjustable discharge power according to capability parameter and test request.
2. Voltage and current value can be displayed with multi-functional digital meter.
3. AC load bank is of all kinds of specifications and series, and include resistance, inductive and capacitive load.
4. Two or more Intelligent AC Load Bank can operate in parallel.
5. It can make stable state test,
6. Remote control by software.
7. Testing data can be saved or transferred by RS485, data can form curve, to be printed.
Function options
Intelligent AC Load Bank have two control patterns: position machine software control and local panel control
Intelligent AC load bank (LED): multi-function digital 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.
