SMD24A Damper Rotary Actuator, 16 Nm, AC/DC 24 V, 20 s - Belimo

Find all the components for your ventilation system at IACS. All Belimo Actuators on hand are eligible for Free Delivery and 1-2 Delivery.

The Belimo SMD24A is a kind of Actuator used to manage dampers in HVAC applications and systems.

To control the damper, this kind of Actuator turns it by Rotary motion.

The Torque used by the SMD24A is 16 Nm.

This Belimo Actuator requests 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.

Manufactured by Belimo, The SMD24A is a damper actuator used to manage and adjust air dampers in ventilation and air-conditioning units.

A rotational motion is generated by this sort of actuator.

The Belimo SMD24A has a Open/Close type of control.

The Torque force is 16 Nm.

Simple direct mounting: Simple direct mounting on the damper spindle with an universal spindle clamp, supplied with an anti-rotation device 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).

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

Adjustable angle of rotation Adjustable angle of rotation with mechanical end stops.
