Belimo SH24A-SR100 - linear actuator for dampers and gates

Belimo SH24A-SR100 – linear actuator

Actuator designed for regulating dampers and gates in stationary heating, ventilation and air conditioning systems. According to the technical data sheet, it supports air dampers with an area of up to approx. 3 m².

Key features

• Actuator force: 450 N; nominal supply: AC/DC 24 V, 50/60 Hz.
• Modulating control: 2...10 V; position feedback signal: 2...10 V.
• Stroke: 100 mm; max. 100 mm, fixed setting. Motor running time: 150 s / 100 mm.
• Motor direction selected by switch; manual override by push-button, with the option to lock it.
• Power consumption during operation: 2.5 W; in the rest position: 0.4 W; for cable sizing: 4.5 VA.
• Power and control connection: 1 m cable, 4x 0.75 mm².
• IEC/EN protection rating: IP54; IEC/EN protection class: III, Safety Extra-Low Voltage (SELV).
• Ambient temperature: -30...50°C [-22...122°F].

The actuator is protected against overload and stops automatically when the end stop is reached. Where lateral forces occur, the documentation requires the use of suitable mounting accessories.
