Belimo 24V AC/DC Open/Close Damper Actuator, 5 Nm Motor Torque LM24A

Belimo LM24A 24V AC/DC Open/Close Damper Actuator is a high-quality rotary/louver actuator designed for precise control of air dampers in ventilation and air-conditioning systems for industrial and commercial buildings.

This actuator operates on stall torque technology, which enables it to function without end limit switches while offering overload proof protection, ensuring safe and reliable operation over a minimum lifetime of 60,000 cycles.

It supports a supply voltage of 24 volts AC/DC, consuming only 1 watt of power, and provides a motor torque of 5 Nm to effectively maneuver dampers up to a maximum area of 1 square meter.

The actuator includes an adjustable U-clamp that accepts both round and square shafts from 6 mm to 20 mm in diameter, making it compatible with a wide variety of HVAC control systems worldwide.

Its operational temperature range extends from -30°C to 50°C, and it features an IP54 ingress protection rating, allowing it to withstand dust and moisture exposure common in building environments.

The compact design produces low noise levels of 35 dBA and achieves a rotation angle of 95° with a running time of 150 seconds for full opening/closing.

Optional auxiliary switches are available, enabling additional control functions with SPDT switches rated at 3 (0.5)A 250Vac, adding flexibility for complex control system integration.

Belimo LM24A actuators are suited for a broad range of applications including HVAC systems, industrial air control, building automation, and thermal management where precise damper positioning is critical.

The actuator operates with a control type of open/close suitable for air damper adjustments. It supports supply voltage of 24V AC/DC with low power consumption of 1W. Ambient temperature range is wide from -30°C to 50°C ensuring durability.

The actuator provides a rotation angle of 95° and runs with a 150-second running time. Its noise level is rated at 35 dBA, maintaining quiet operation. Equipped with IP54 rating, the actuator offers protection against dust and water splashes.
