Product Description


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 has 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.

Main 10 Technology Advantages

Kaixiang company is in leading position in generator set testing and maintenance industry, besides general functions, its load bank has following unique advantages:
1. Standard Testing Function: System can do stable test, transient test, and realize functions, such as setting, fluctuation, instant load, and instant unload.
2. Super Power Load: high load power density, large capacity of single set, parallel running to finish super power testing, and realize tens of megawatts of power loading.
3. Accurate Data: with high precision data collection module and measuring meter, related equipment has passed the certification by CMA (China Metrology Accreditation) qualification testing institution, and ensure the reliability of data.
4. Flexible Control Mode: based on different using habit, several control mode as following can be choosed, local panel operation, remote box controlling, and intelligent software. 
5. Intelligent Load: after setting generator rated power in software, system realize rapid loading through preset proportion, automatically and continuously load multiple power value and common tests, like stepping, full load, and over load, so that improve working efficiency.
6. High Efficiency Data Management: display real-time testing data, generate form, curve graph or report automatically, also can put data into storage. According to generator set No. set up testing file, support to query at any time, and improve data management efficiency.
7. Comprehensive Protection Function: multiple protection, like over temperature, smoke. When in danger, automatically terminate the test and give alarm to protect safety of personnel and equipment.
8. Stable Running: with the latest generation control module as the core, a sharp rise in system response speed and anti-interference performance, avoid function failure in complex electrical environment, and ensure system running stably and reliably. 
9. New Load Bank Technology: using the international advanced AC load bank technology, overcome the old water bank defects, such as bear bumpy, unable to use when go to sea, realize Mooring Trial and Sea Trail, and simulate the real working condition of generator running.  
10. Mature Manufacturing Technology: load element using excellent anti-corrosion materials, waterproof insulation container packaging, suitable for adverse environment such as ocean. Internal layout is reasonable, air channel is clear, rapid heat emission, and satisfy continuous working need.
