AC220V-500kW Dummy Load Bank With Frequency 60 HZ And Black , Grey Colour
Introduction
AC220V-500kW Dummy Load Bank With Frequency 60 HZ can simulate the real working conditions and provides a rigorous test regime for power supplies from 1kW to 60MW. Resistive,inductive(reactive),capacitive or combined load banks can be customised for any application.
Load banks can be supplied for most powers, voltages, frequencies and sizes.
Multi-voltage load banks are also available for operation over a large voltage range. At the same time, It can operate in parallel with more than two units.
Application
1. To reducewet stacking problems
2. Periodic excercising of stand-by engine generator sets
3. Battery system testing32.Load optimization in prime power applications
4. Factory test of turbines
5. factory test of engine generator sets

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.
Local meter display data: Local meter can display 3 phases voltage, current, active power, frequency and so on.
