Description
DEIF HAS-111DG Paralleling Relay
Generator Synchronizer • DEIF Uni-line Marine Series
CAT III 600V Rated
The genuine DEIF HAS-111DG is a high-precision, microprocessor-controlled paralleling relay engineered for manual or semi-automatic synchronization of a generator to a busbar or utility grid in demanding maritime and industrial applications. Designed to meet stringent CAT III 600V safety standards, this marine-grade instrument monitors voltage, frequency, and phase angle differences between the generator and the busbar to ensure seamless connection without electrical disturbances. It features front-accessible adjustment potentiometers and built-in LED status indicators for reliable switchboard operations.
Cosmetic Note & Condition Disclosure:
This pre-owned module has a minor cosmetic defect: one side fitting/mounting hole was broken during dismantling. This does not affect the internal microprocessing circuitry, front-facing adjustment dials, or terminal block pins.
