Description

The EF..24-SR series actuators provide true spring return operation for reliable failsafe application and positive close off on air tight dampers. The spring return system provides constant torque to the damper with, and without, power applied to the actuator. The EF..24-SR series provides 95 degree of rotation and is provided with a graduated position indicator showing 0degree to 95 degree. The EF..24- SR uses a brushless DC motor which is controlled by an Application Specific Integrated Circuit (ASIC) and a microprocessor.
