RDAB10S-S is a spring return actuator for operating air control dampers to an open or closed position during power failures.
Operation
When the supply voltage is connected the actuator moves to its working position, while at the same time the spring return tenses. If the supply voltage is interrupted, the energy stored in the spring is released, returning the actuator to its safe position.
