SIEMENS Actuator SAS61.53

Core Features "SAS61" Series & Functional Design: The "SAS61" denotes Siemens’ versatile medium-duty electric rotary actuator series, specialized for airflow control in mid-sized dampers. The "53" model is a 24V AC-powered rotary actuator with a 90° rotation angle (standard for commercial/industrial dampers) and a torque rating of 5 Nm—ideal for medium-sized air dampers in HVAC air handling units (AHUs), commercial ductwork, or light industrial ventilation systems where balanced torque and precision are needed. Dual Control Modes & Precision Feedback: Equipped with flexible control options to adapt to diverse airflow scenarios: Modulating control (0–10V DC input): For variable air volume (VAV) systems or process ventilation, enabling precise damper opening adjustment with ±2% positioning accuracy—critical for stable temperature or pressure control (e.g., office building VAV boxes). On/off control (24V AC input): For simple full-open/full-close applications (e.g., zone isolation dampers), ensuring rapid response to basic airflow demands. It includes built-in analog position feedback (0–10V DC) for real-time status monitoring, compatible with building management systems (BMS) or industrial PLCs for centralized control. Robust & Space-Efficient Construction: Engineered with a corrosion-resistant aluminum alloy housing and a weight of 1.1 kg (2.43 lbs), suitable for wall, bracket, or direct damper mounting in commercial/industrial spaces (e.g., HVAC mechanical rooms, factory duct enclosures). The housing features IP54 protection (dust-tight, water-resistant), withstanding moisture, dust, and mild vibration—ideal for indoor commercial and light industrial environments. Safety & Reliability Features: Built with safeguards to ensure long-term uptime: Electronic overtorque protection: Automatically stops the motor if torque exceeds 5 Nm (e.g., jammed damper from debris), avoiding mechanical damage to the actuator or damper. Dual end-stop limits: Mechanical and electronic limits prevent over-rotation beyond 0° (closed) and 90° (open), protecting damper seals and extending component lifespan. Wide voltage tolerance: Accepts 24V AC (50/60 Hz) input with ±15% fluctuation tolerance, ensuring stability in standard HVAC control system power supplies. Easy Integration & Installation: Designed for seamless compatibility with Siemens BMS controllers (e.g., Desigo PX) and third-party PLCs via standard 0–10V analog signals. It includes a universal damper shaft adapter (fits 6–12 mm diameter shafts) and pre-labeled wiring terminals, reducing installation time by up to 25% vs. non-standard actuators. No specialized tools are required for setup. Typical Applications SIEMENS Actuator SAS61.53 is engineered for medium-duty rotary control of mid-sized dampers—ideal for scenarios needing 5 Nm torque, precision positioning, and commercial-grade durability in HVAC or light industrial ventilation. Key use cases include: HVAC Variable Air Volume (VAV) Boxes: Controlling dampers in commercial building VAV boxes (e.g., office floors, hotels). Modulating control adjusts airflow to match room temperature demand, while IP54 protection withstands mechanical room dust—complying with EN 13141-6 (ventilation for non-residential buildings) and ASHRAE 90.1 (energy efficiency). Medium Air Handling Units (AHUs): Regulating supply/return air dampers in commercial AHUs (e.g., retail stores, hospitals). On/off control manages AHU startup/shutdown, and position feedback enables BMS monitoring of damper status—complying with EN 1886 (air handling units) and ISO 16813 (HVAC system design). Light Industrial Ventilation: Adjusting dampers in small factory ductwork (e.g., electronics assembly lines, food packaging facilities). Electronic overtorque protection handles occasional debris jams, and corrosion-resistant housing prevents damage from mild industrial dust—complying with ISO 12591 (industrial ventilation standards). Commercial Smoke Control Dampers: Controlling dampers in commercial building smoke management systems (e.g., shopping malls, airports). On/off control enables emergency closure to contain smoke, and IP54 protection suits public building mechanical spaces—complying with EN 12101-6 (smoke control dampers) and local fire codes.
