Belimo LHQ24A-SR100 - modulating linear actuator

Belimo LHQ24A-SR100 – linear actuator

Modulating actuator designed for controlling dampers and slide valves in building services systems. According to the technical data sheet, it is suitable for air dampers with an area of up to approx. 0.7 m².

Key features and parameters

• Actuating force: 100 N.
• Nominal voltage: AC/DC 24 V; frequency: 50/60 Hz.
• Control range Y: 2...10 V; position feedback signal U: 2...10 V.
• Stroke: 100 mm; max. 100 mm, adjustable in 20 mm increments. Minimum permitted stroke: 40 mm.
• Motor running time: 3.5 s / 100 mm.
• Power consumption during operation: 13 W; in the rest position: 2 W; for cable sizing: 23 VA.
• Power and control connection: 1 m cable, 4x 0.75 mm².
• Direction of movement selected by switch; manual adjustment using a push-button with locking option.
• Degree of protection IEC/EN: IP54; protection class IEC/EN: III, Safety Extra-Low Voltage (SELV).
• Ambient temperature: -30...40°C [-22...104°F].

When the power is first switched on, the actuator adapts the operating range and feedback signal to the set mechanical range. Adaptation can also be started using the push-button; it is required after changing the stroke limit.
