Information About EFB120-S
The EFB120-S is a rugged electromechanical drive built to ensure fail-safe environmental regulation in expansive mechanical networks. It utilizes standard line voltage, eliminating the need for dedicated control transformers in the electrical cabinet. Designed to protect facility infrastructure, it incorporates a mechanical spring mechanism that forces the damper to a safe position during power failures. This actuator features two integrated SPDT auxiliary switches that signal precisely when the damper reaches designated open or closed thresholds.
Key Features:
-
Line Voltage Operation: Connects directly to 120V AC power grids without requiring secondary voltage transformers.
-
Extreme Torque Capacity: Generates 270 lb-in of rotational force to actuate oversized commercial dampers effortlessly.
-
Spring-Return Safety: Drives the damper mechanically to a secure fail-safe state during electrical grid interruptions.
-
Auxiliary Switch Feedback: Utilizes two integrated SPDT switches to report mechanical positions back to the main controller.
-
Direct Coupled Mounting: Secures directly to standard damper shafts to eliminate slop from external mechanical linkages.
-
Rugged Metal Housing: Protects internal gearing and electrical components from severe mechanical room vibrations.
The EFB120-S delivers the reliability and precision required for heavy damper actuation and critical fail-safe ventilation.
