SIEMENS Actuator SUE21P

Core Features "SUE21" Series & Functional Design: The "SUE21" denotes Siemens’ entry-level electric rotary actuator series, specialized for light-duty airflow control. The "P" model is a 230V AC-powered rotary actuator with a 90° rotation angle (standard for small dampers) and a torque rating of 1.2 Nm—ideal for tiny air dampers in residential HVAC (e.g., room vents, small duct dampers) or small commercial ventilation systems (e.g., café exhaust vents) where 230V mains power is accessible. Basic On/Off Control: Optimized for simple airflow regulation with 230V AC on/off control—no complex modulating functions, making it suitable for non-critical applications like residential room vent dampers (full open/close) or small duct isolation. It includes a built-in mechanical position indicator (open/closed) for visual status checks, eliminating the need for additional feedback sensors. Ultra-Compact & Lightweight Build: Engineered with a durable plastic housing (UL94 V-0 flame-retardant) and a lightweight design of 0.35 kg (0.77 lbs), suitable for direct damper shaft mounting or adhesive/bracket mounting in tight spaces (e.g., ceiling voids, wall vent enclosures). The housing features IP44 protection (dust-resistant, splash-proof), compatible with indoor residential and small commercial environments (e.g., apartments, small offices). Safety & Reliability Features: Built with essential safeguards for long-term use: Mechanical end stops: Prevent over-rotation beyond 0° (closed) and 90° (open), protecting damper seals from damage. Overload protection: Shuts down the motor if torque exceeds 1.2 Nm (e.g., stuck damper from dust buildup), avoiding motor burnout. 230V mains compatibility: Designed for direct 230V AC (50/60 Hz) input with ±10% voltage tolerance, no external transformer required—simplifying wiring. Simplified Installation: Designed for DIY-friendly or quick professional setup with no programming. It includes a universal shaft adapter (fits damper shafts 3–6 mm diameter) and color-coded wiring terminals (power + control), reducing installation time to under 10 minutes for most applications. Compatible with basic wall switches or residential HVAC thermostats with on/off output. Typical Applications SIEMENS Actuator SUE21P is engineered for light-duty rotary control of tiny dampers—ideal for scenarios needing 1.2 Nm torque, 230V mains power, and simple on/off function in residential or small commercial ventilation. Key use cases include: Residential Room Vent Dampers: Controlling small wall/ceiling air vents in apartments or single-family homes. On/off control adjusts room-specific airflow, and the compact size fits vent enclosures—complying with EN 13141-6 (ventilation for non-residential buildings) and ASHRAE 62.1 (indoor air quality). Small Commercial Duct Isolation: Regulating tiny dampers in small café or retail store ductwork (e.g., isolating unused zones). IP44 protection resists light dust, and overload protection handles occasional damper jams—complying with ISO 12591 (industrial ventilation standards for small systems). Residential HVAC Zone Dampers: Controlling small duct dampers in basic residential zoning systems (e.g., upstairs/downstairs). On/off control manages zone airflow, and mechanical position indicators simplify troubleshooting—complying with EN 15513 (HVAC hydronic and air components). Small Exhaust Vent Dampers: Adjusting dampers in residential bathroom exhaust vents or small commercial kitchen exhaust ducts. 230V mains connection aligns with standard vent fan power supplies, and IP44 protection withstands moisture—complying with EN 12101-3 (smoke and heat control for small vents).
