Belimo SM230P damper actuator

The RobustLine model is designed to control dampers in HVAC systems, comparable industrial systems and technical building installations. According to the documentation, it is intended for air dampers with an area of up to approx. 4 m². The design is suitable for outdoor applications and exposure to moisture, condensation, UV radiation and chemical influences.

Key features and specifications

• Motor torque: 20 Nm; control: Open/Close, 3-point.
• Rated voltage: AC 100...240 V; frequency: 50/60 Hz.
• Power consumption: 2.5 W during operation, 0.6 W in the resting position; sizing power: 6 VA.
• Motor running time: 150 s / 90°; rotation angle: max. 95°, with mechanical limiters adjustable on both sides.
• Direction of movement selected by switch: 0 (rotation to the left) / 1 (rotation to the right).
• Manual override by push-button with locking option; mechanical position indicator.
• Mechanical connection: universal clamp 14...20 mm; power and control connection: 1 m cable, 3x 0.75 mm², halogen-free.
• IEC/EN protection rating: IP66/67; ambient temperature: -30...50°C [-22...122°F].

The actuator can be mounted directly on the damper shaft using the universal clamp. The mechanism prevents rotation relative to the shaft. The version with a built-in heater, intended for operation at lower temperatures, is a separate option and is not standard equipment on the SM230P model.
