Field Application Relay GCDT-02E

Device for control of synchronism of synchronous motors, through control of field application, based upon frequency of slip of rotor and polar angle.
It allows applying excitation in exciter field already in motor start.
It executes the crowbar function, placing the start resistance in parallel with field during the start.
Compact and resinous construction, being able to be installed in the rotor of the brushless motor.
Handles a wide range of variation in the power supply voltage.
