The Belimo SM24A Damper Actuator is a reliable and efficient solution for controlling air dampers in HVAC systems. This actuator is designed to operate with a nominal voltage of AC 24 V, 50/60 Hz or DC 24 V, with a voltage range of AC 19.2 to 28.8 V or DC 21.6 to 28.8 V.
With a power consumption of 2 W at nominal torque and 0.2 W at rest, this actuator offers energy efficiency without sacrificing performance. The actuator also comes with a 1-meter cable, 3 x 0.75 mm2, making it easy to connect to your HVAC system.
The Belimo SM24A offers a nominal torque of at least 20 Nm at nominal voltage, making it capable of smoothly and accurately controlling dampers. The direction of rotation is reversible with switch 0 or 1, providing flexibility in operation. The actuator also has a manual override feature, allowing you to disengage the gearing latch with a push button and lock it for convenience.
The angle of rotation of the Belimo SM24A is a maximum of 95° and can be limited at both ends with adjustable mechanical end stops. It also has a running time of 150 s / 90°, ensuring smooth and accurate operation. Additionally, the actuator has a maximum sound power level of 45 dB (A) and position indication is mechanical and pluggable.
Safety is a top priority with the Belimo SM24A, which is why it operates under Type 1 mode of operation and has a rated impulse voltage of 0.8 kV. It also has a control pollution degree of 3, making it safe to use in a variety of environments. The ambient temperature range is –30 to +50°C, while the non-operating temperature range is –40 to +80°C. The actuator is maintenance-free, making it a reliable solution for your HVAC system.
The Belimo SM24A Damper Actuator has dimensions of approximately 1 kg, making it lightweight and easy to install. Its compact design allows it to fit seamlessly into your HVAC system while providing superior performance. Overall, this actuator is an excellent choice for those who want to achieve precise and efficient control over their air dampers.
