Features
◆When running with load, it can run in three excitation modes: constant power factor, constant voltage, and constant excitation.
◆No-load V/F given characteristics, long-term low-speed standby, to ensure that the excitation current will not be too large.
◆Constant voltage mode can set the size of reactive power adjustment to ensure stable and balanced reactive power distribution for multiple machines running in parallel.
◆Grid-connected constant power factor operation function, no matter whether the load is added or subtracted, there is no need to manually adjust the excitation in the whole process.
◆Detection current with the same name termination reverse alarm function.
◆Load shedding automatic voltage regulation function, no need to manually adjust the excitation when the load trips.
◆No-load automatic tracking grid voltage function, which can ensure the smooth input of grid connection.
◆Automatic de-excitation of no-load overvoltage or overfrequency, and the value can be set.
◆No-load low-frequency (adjustable) de-excitation function, no need to manually turn off the excitation during shutdown.
◆Force, over-excitation, under-excitation limit function, the size can be set.
◆Chinese LCD display function, which can display grid voltage, generator voltage, current, frequency, power factor, and percentage value of excitation voltage.
◆Full Chinese setting menu, simple and clear, you can debug parameters without manual
technical parameter

◆Scope of application: All kinds of medium and small generators.  
◆Input Signal
◆Measured voltage: generator voltageAC0-600V(High voltage generator can be customizedAC0-150V ).  
Grid voltageAC0-600V(The high-voltage generator can be customizedAC0-150V) (stand-alone operation is not catch).  
◆Adjustment current: connect to nominalAC5A on the secondary side of the current transformer (and current out of phase with the generator measurement voltage).  
Excitation power supply (brushless): ratedAC200-240V. (beyond the scope needs to be customized).  
Sync voltage (with brush): ratedAC380V. (beyond the scope needs to be customized).  
◆Grid-connected signal(Close feedback): use the main switch closing signal (normally open or normally closed, which can be set).  
◆Brushless excitation rated output: voltage20160V; the current does not exceed 10A, the maximum excitation current does not exceed20A. (beyond the scope needs to be customized).
