Belimo 240V AC Open/Close Damper Actuator 5 Nm Torque IP54 LM230A-S

Belimo LM230A-S is a high-quality open/close damper actuator designed for effective control of air dampers in ventilation and air conditioning systems. Operating on a supply voltage of 240V AC, this actuator delivers a motor torque of 5 Nm, suitable for damper areas up to 1 square meter, making it ideal for HVAC use in commercial and industrial environments.

This actuator features a robust IP54 rated enclosure that protects internal mechanisms from dust ingress and water splashes, ensuring reliability and long service life. It incorporates a manual pushbutton override and direction change switch for ease of operation and maintenance.

The adjustable U-clamp design accepts both round and square spindles ranging from 6 mm to 20 mm, enhancing compatibility with various damper types. Its quiet operation at 35 dBA noise level suits applications requiring minimal sound disturbance.

Equipped with stall torque technology, the LM230A-S actuator is overload-proof and does not require mechanical end switches. The integrated auxiliary switch (1xSPDT) supports additional control and signaling functions, expanding its application flexibility.

With a runtime of 150 seconds and an angle of rotation of 95°, it ensures accurate damper positioning. The actuator operates efficiently at power consumption of only 1.5W and is rated for ambient temperatures ranging from -30°C to 50°C, allowing usage in diverse climatic conditions.

Compliance with RoHS, CE, and EN standards confirms the actuator’s adherence to stringent environmental and safety regulations. The product is made in Switzerland, reflecting high manufacturing quality.

This Damper Actuator is extensively used in HVAC systems for controlling ventilation, heating, and cooling airflow in commercial buildings, industrial plants, and institutional facilities. Its reliable performance serves industrial, laboratory, manufacturing, and commercial air management needs.
