The Belimo SMQ24G-SR is a damper actuator used to modify air dampers in ventilation and air-conditioning systems.

This specific type of actuator applies a rotary motion.

The Belimo SMQ24G-SR has a modulating control type.

The Torque is 16 Nm.

Features
 

• Fields of application The actuator is particularly suitable for utilisation in outdoor applications and is protected against the following weather conditions:
  – UV radiation
  – rain / snow
  – dirt / dust
  – humidity
  – Changing atmosphere / frequent and severe temperature fluctuations (recommendation: use the actuator with integrated factory-installed       heating which can be ordered separately to prevent internal condensation *)


• Mode of operation The actuator is controlled with a standard modulating signal of DC 0 ... 10 V and moves to the position defined by the control signal. The measuring  voltage U serves for the electrical display of the damper position 0 ... 100% and as slave control signal for other actuators.
  


• Simple direct mounting Simple direct mounting on the damper spindle with a universal spindle clamp, supplied with an anti-rotation strap to prevent the actuator from rotating.
  


• Manual override Manual override with push-button possible (the gear is disengaged for as long as the button is pressed or remains locked).
  


• Adjustable angle of rotation Adjustable angle of rotation with mechanical end stops.A minimum permissible angle of rotation of 30°<) must be allowed for.


• High functional reliability The actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached.


• Home position The first time the supply voltage is switched on, i.e. during initial startup, the actuator carries out an adaptation. After pressing the «gear disengagement» pushbutton, the actuator moves to the home position at the end stop.


• Adaption and synchronisation During adaptation, the upper and lower spindle end stop is recorded and deposited in the actuator. Detection of the mechanical end stops enables a gentle approach to the end positions and thus protects the actuator mechanism.During synchronisation, the actuator moves to the home position for angle referencing. This ensures correct position regulation.
