AC400V-500kW Adjustable Load Bank In High Performance With Frequency 50 HZ
Introduction
(1) The system consists of 1 sets of 500kW Resistive load bank. The System is made up of two parts of measurement and control and load, mainly including AC dry load, automatic data acquisition system, automatically loading and unloading control system, the cooling device, auxiliary control, PC software and so on.
(2) This system, which is of independent research and development of electricity load test equipment by our technology, combining dry load module with the automatic measurement and control module, can accurately detect all kinds of generator output power and load capacity, full load and overload test.
Application
1. Periodic excercising of stand-by engine generator sets
2. Ups system testing
3. Load optimization in prime power applications
4. Factory testing of turbines
5. factory testing of engine generator sets
6. To reducewet stacking problems

Main features
Local meter display data: Local meter can display 3 phases voltage, current, active power, frequency and so on.
Load testing: Can load power that within the rated power, test and display stable state 3 phases voltage, current, active power, frequency, working time, etc of generator sets.
Load/unload with one key: Either by manual control, or software control, user can preset the power, then press load master button. Load bank will load according to preset power.
Control Pattern: User can choose local control and intelligent control.
Local Control: There are several power steps in panel; user can load/unload by buttons.
Intelligent Control: Through data processing software in PC, user can make automatic load, display, record and manage testing data, form curves and tables, also print them.
Control Pattern interlock: There is control pattern switch, when choose one control pattern, the other pattern is invalid to avoid the clash.
