Features & Benefits

• The GK..24-SR actuator provides 95 Degree of rotation and a visual indicator shows the position of the actuator
• When reaching the damper or actuator end position the actuator automatically stops
• The gear can be manually disengaged by pressing the button located on the actuator cover
• The GK..24-SR actuators use a brushless DC motor, which is controlled by an Application Specific Integrated Circuit (ASIC)
• The ASIC monitors and controls the actuators rotation and provides a digital rotation sensing (DRS) function to prevent damage to the actuator in a stall condition
• Power consumption is reduced in a holding mode
• The actuator is electronically protected against overload
• The anti-rotation strap supplied with the actuator will prevent lateral movement
• Add-on auxiliary switches or feedback potentiometers are easily fastened directly onto the actuator body for signaling and switching functions
