Abstract
There is provided an electro-optically driven relay system (10) for switching the application of energy to a load (5). The subject relay system (10) comprises: a switch unit (100) operable responsive to a control signal; an electro-optic current generating unit (200) connected to the switch unit (100) for generating the necessary control signal responsive to an actuation signal; and, primary and supplemental drive units (300, 400) connected to the electro-optic current generating unit (200) for collectively generating the actuation signal. The primary drive unit (300) is operable responsive to a first input signal; and, the supplemental drive unit (400) is operable responsive to a second input signal to augment the actuation signal for at least a predetermined time duration. The switching response of the switch unit (100) is thereby accelerated.
