Air Damper Actuators with Spring Return GPC..1A

Description: The Air Damper Actuators with Spring Return GPC..1A are electric motor-driven rotary actuators designed for open-close, three-position, and modulating control in ventilation and air conditioning systems. With a nominal torque of 4 Nm, these actuators provide reliable operation and include a spring return for emergency functionality.

Key Features:

  • Nominal Torque:
    • Offers a substantial 4 Nm of torque for efficient operation.
  • Operating Voltage:
    • Available in AC 24 V~, DC 24-48 V⎓, or AC 100-240 V~ options for versatile compatibility.
  • Emergency Function with Spring Return:
    • Features an emergency function with spring return for safe damper positioning during power outages.
  • Pre-Wired Design:
    • Comes prewired with a 0.9 m connecting cable for easy installation.
  • Position Indication:
    • Provides clear indication of the actuator's position for enhanced control.
  • Auxiliary Switches:
    • Equipped with auxiliary switches for additional functions.

Spring Return Mechanism:

  • Operation:
    • The spring return actuator drives the damper to the desired position when connected to the operating voltage, simultaneously tensioning the integrated spring.
    • In case of a power outage, the spring return automatically drives the damper to the defined emergency position.
  • Spring Preload:
    • Includes a spring preload of 5° to ensure secure closure of air dampers.

Features:

  • Reliable Operation:
    • Utilizes brushless, robust DC motors for reliable operation regardless of load.
  • End Position Handling:
    • Does not require an end position switch, remains in place upon reaching the end stop, and is overload-proof.
  • Maintenance-Free Gears:
    • Gears are maintenance-free and produce minimal noise.
  • Shaft Fixation:
    • Offers simple and reliable shaft fixation for ease of installation.
  • Mounting Bracket Included:
    • Comes with a mounting bracket for convenient installation.

Use:

  • Application:
    • Ideal for ventilation and air conditioning plants to operate air dampers that must be rotated to a defined emergency position during power outages.
  • Damper Area:
    • Suitable for damper areas up to 0.6 m², dependent on friction.
  • Controller Compatibility:
    • Compatible with modulating controllers (DC 0/2...10 V), open-close, or three-position controllers.
  • Zone Damper Control:
    • Suitable for directly driven zone dampers to control air flow in air ducts.
  • Recommended Pulse Length:
    • It is recommended to have a minimum pulse length of 500 ms for actuators operated with three-point control to ensure continuous and accurate operation.
