Series 19 SAV Failsafe


Series 19 Smart SAV Failsafe Electric Actuators

A failsafe actuator cycles as on/off while charging internal capacitors. When power is lost, the capacitors discharge and power the unit to a predetermined fail position. When power is restored, the capacitors charge up again.
