NMQ24A - Belimo Damper actuator 8 Nm, 4.0 s, 95°

Find all parts for your ventilation system at iacs, the Free Delivery and 1-2 Delivery is available for all the Belimo Actuators in stock

The Belimo NMQ24A is a type of Actuator used to control dampers in HVAC systems and applications.

This kind of Actuator rotates the damper in order to control it.

The force applied by the Torque of the NMQ24A is 8 Nm.

This Rotary Actuator needs to be supported by a power supply of 24Vac/Vdc.

If you have questions concerning size or installation, refer to the Belimo custom datasheet above or email iacs for individualised support.

NMQ24A-TP - Damper actuator 8 Nm, 4.0 s, 95°

Features
 

• 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 pushbutton possible (the gear is disengaged for as long as the button ispressed 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 When the supply voltage is switched on for the first time, i.e. at commissioning or after pressingthe „gear disengagement“ switch, Pos. Direction of rotation switch Home positionY = 0 Left stop1 Y = 0 Right stop the actuator travels to the home position.The actuator then moves into the position defined by the control signal.



• 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.
