The changeover switch is a microprocessor based intellectual device designed to transfer loads automatically and manually from one power source to another in a wide variety of 1-3 phase applications.
The unit monitors 3-phase normal and reserve source voltages, sends remote start command to the generating set and performs changeover switching between those 2 sources connecting the load circuits to a power source having voltages within preset limits.
Device has a manual load switch lever, a manual/auto mode switch and a mechanical locking.
Inputs and outputs: fire linkage control, generator remote start, external indicators.
The front panel leds provide information about mains and generator power availability as well as a current switch positions.
