FEATURES

 Current limitation – limit can be adjusted via a potentiometer (IEXC.)
 Over-temperature protection – as the heat sink temperature crosses a threshold EX-10 output shuts-off
 Short-circuit protection – when transient current output exceeds a threshold, the EX-10 decreases the
excitation output to below 0.2A until shutdown

In conjunction with easYgen-3400/3500XT genset controls, the active voltage regulator system offers:
 Automatic Voltage Regulation (AVR)
 Soft start functionality
 Under frequency regulation (Volt/Hz) defined by five configurable points and activated by
LogicsManager
 Line drop compensation via AnalogManager
 Power factor and kvar control
 Voltage droop compensation
 Fault Ride Through (FRT) support
 Setpoint configuration and AVR status overview on the easYgen screen and on Woodward ToolKit
