Core Features "ASC10" Series & Functional Design: The "ASC10" denotes Siemens’ ultra-light-duty linear actuator series, optimized for micro-scale valve control in compact systems. The "51" model is a 24V AC-powered linear actuator with an 8 mm stroke length and 200 N thrust rating (≈20.4 kgf)—ideal for ultra-small hydronic valves (e.g., mini-split zone valves, appliance fluid valves) where minimal force, 24V low-voltage power, and ultra-compact size are critical. Basic Control Modes & Optional Feedback: Equipped with simple control to meet micro-flow needs: On/off control (24V AC input): For basic full-open/full-close scenarios (e.g., appliance fluid on/off, small HVAC zone control), ensuring reliable operation with low noise. Modulating control (0–10V DC input, optional): For precision micro-flow adjustment (e.g., small HVAC temperature trimming), enabling valve opening adjustment with ±3.5% positioning accuracy—sufficient for non-critical micro-environment control. It includes optional analog position feedback (0–10V DC) for status monitoring, compatible with small HVAC controllers or appliance control boards. Ultra-Compact & Lightweight Build: Engineered with a high-impact plastic housing (UL94 V-0 flame-retardant) and an ultra-lightweight design of 0.25 kg (0.55 lbs), suitable for direct micro-valve mounting or tight-space installation (e.g., appliance interiors, mini-split control boxes). The housing features IP44 protection (dust-resistant, splash-proof), compatible with indoor small HVAC or appliance environments (e.g., residential mini-splits, compact refrigerators). Safety & Reliability Features: Built with safeguards for micro-scale operation: Overthrust protection: Automatically stops the motor if thrust exceeds 200 N (e.g., micro-valve jamming from debris), avoiding motor burnout or valve damage. Mechanical end stops: Prevent over-extension beyond full open/close positions, protecting delicate micro-valve seals and extending service life. Wide voltage tolerance: Accepts 24V AC (50/60 Hz) input with ±10% fluctuation tolerance, ensuring stability in low-voltage appliance/HVAC control systems. Simplified Integration & Installation: Designed for plug-and-play setup with no complex programming—works with Siemens small HVAC controllers or appliance control boards via standard 24V on/off or 0–10V signals. It includes a micro-valve adapter (compatible with 3–5 mm valve stems) and color-coded wiring terminals, reducing installation time to under 10 minutes for most applications. Typical Applications SIEMENS Actuator ASC10.51 is engineered for ultra-light-duty linear control of micro valves—ideal for scenarios needing 200 N thrust, 8 mm stroke, and 24V power in small HVAC or appliance systems. Key use cases include: Residential Mini-Split Zone Valves: Controlling ultra-small 2-way hydronic valves in mini-split ductless systems (e.g., room-specific airflow control). On/off control manages zone fluid flow, while ultra-compact size fits mini-split indoor units—complying with EN 14511 (small HVAC components) and ASHRAE 90.2 (residential energy efficiency). Compact Appliance Valves: Regulating micro valves in small appliances (e.g., compact refrigerators, countertop water dispensers). Optional modulating control adjusts fluid flow, and IP44 protection withstands appliance moisture—complying with EN 15502 (appliance standards). Small HVAC Duct Valves: Adjusting tiny dampers in narrow HVAC ducts (e.g., bathroom exhaust ducts, under-cabinet HVAC) for airflow on/off. Lightweight design avoids duct strain, and quiet operation suits living spaces—complying with EN 13141-6 (small ventilation systems). Lab Equipment Fluid Valves: Controlling micro valves in small lab equipment (e.g., sample cooling units, mini water baths). Basic on/off control manages fluid supply, and compact size fits lab device enclosures—complying with lab safety equipment standards.
