Brief Overview
General information
The ”easYgen | exciter-10“ (= ”EX-10“) is a generator excitation driver module designed
for operation together with the genset control unit ”easYgen 3400/3500XT“ (release 1.16
or higher). The controller function is inherent to the easYgen. The easYgen measures the
generator values like voltage, power factor etc. and compares it with the valid set point.
According to the deviation, the easYgen controls an ”Excitation command“, which is fed
to the ”easYgen | exciter-10“ as a PMW signal. The ”easYgen | exciter-10“ then provides
the generator eld excitation current according to the PWM signal.
The excitation power supply can be from shunt, auxiliary winding or permanent magnet
(PMG) type with either single phase or three phase.

The easYgen | exciter-10 is equipped with temperature protection, to prevent failure and
damage caused by overheating. In occurrence of overheating, the exciter will shut-down
until normal operating temperature is reached then automatically restarts operation
Features:
In conjunction with easYgen-3400/3500XT genset controls, the active voltage regulator
system oers:
• Automatic Voltage Regulation (AVR)
• Soft start functionality
•
Under frequency regulation (Volt/Hz) dened by a congurable 5-point characteristic
and activated by LogicsManager
• Line drop compensation via AnalogManager
• Power factor and kvar control
• Voltage droop compensation
• Fault Ride Through (FRT) support
• Setpoint conguration and AVR status overview on the easYgen screen and on
