Information About GRK24A-5
The GRK24A-5 is a rotary actuator with a spring-return mechanism for applications requiring automatic positioning during power loss. Its AC/DC 24 V supply and open/close control configuration support compatible low-voltage HVAC control systems. The actuator features an F05 connection flange, manual override through a push-button, and an adjustable fail-safe position using the POP rotary knob. NEMA 2 and UL Enclosure Type 2 protection, along with an operating temperature range of -30 to 50°C, support installation in the specified environmental conditions.
Key Features:
- 24 V Operation: Supports AC/DC 24 V power for low-voltage HVAC installations.
- 40 Nm Torque: Provides 40 Nm of motor torque for compatible damper applications.
- Open/Close Control: Uses two-position control for straightforward actuator operation.
- Spring Return: Provides automatic fail-safe positioning during power interruption.
- 95° Rotation: Provides the specified angular travel for rotary damper operation.
- Adjustable Fail-Safe Position: Allows fail-safe positioning to be configured using the POP rotary knob.
- Manual Override: Includes a push-button for manual actuator positioning.
- F05 Connection Flange: Uses an F05 flange connection for compatible equipment.
The GRK24A-5 delivers the reliability and precision required for open/close HVAC damper control and fail-safe rotary air-handling applications.
