Belimo LMQ24A - damper actuator

Belimo LMQ24A – damper actuator

Actuator designed for controlling dampers in building services systems. According to the technical data sheet, it is suitable for air dampers with an area of up to approx. 0.8 m². Close/Open control is not suitable for 3-point control.

Key features and parameters

• Torque: 4 Nm; rated voltage: AC/DC 24 V; rated voltage frequency: 50/60 Hz.
• Motor running time: 2.5 s / 90°; rotation angle: max. 95°.
• Direction of movement selected using switch 0 (rotation to the left) / 1 (rotation to the right).
• Mechanical limiters allow the rotation angle to be limited on both sides; the minimum permitted rotation angle is 30°.
• Push-button manual override with lock option; mechanical position indicator.
• Universal clamp 8...26.7 mm for mounting on the damper shaft.
• Power consumption during operation: 13 W; at rest: 2 W; sizing power: 23 VA.
• Power and control connection: Cable 1 m, 3x 0.75 mm².
• IEC/EN degree of protection: IP54; IEC/EN protection class: III, Safety Extra-Low Voltage (SELV).
• Ambient temperature: -30...40°C [-22...104°F].

Adaptation is required after commissioning and after every adjustment of the rotation angle. Power must be supplied from an isolating transformer.
