Description
Safety Features
The 7710 Single Phase Solid State Relay
(SSR) power regulator offers reliability
coupled with economy. With three firing mode
choices, the 7710 may be applied to virtually
any single phase load. The SSRs include
highly reliable back to back SCRs. The
extended lugs for load connection, simplify
wiring.
Personnel Safety
The 7710 series develop their control circuit
power directly from the control signal.
Additional power supplies or transformers are
not needed.
