SIEMENS Actuator SKP25.003E2

Core Features "SKP25" Series & Functional Design: The "SKP25" denotes Siemens’ ultra-light-duty linear actuator series, specialized for compact control of micro-dampers in residential and small commercial airflow systems. The "003E2" model is a 24V AC-powered linear actuator with a 10 mm stroke length and 80 N thrust rating (≈8.16 kgf)—ideal for tiny air dampers (e.g., residential bathroom exhaust dampers, small commercial mini-ventilation units) where 24V low-voltage power, ultra-compact size, and quiet operation are prioritized. Basic Control Modes & Optional Feedback: Equipped with simple control to meet micro-airflow needs: On/off control (24V AC input): For basic full-open/full-close scenarios (e.g., residential bathroom exhaust on/off, small commercial equipment ventilation), ensuring stable regulation with ultra-quiet actuation (≤28 dB) and fast response (≈2.9 seconds/full stroke). Modulating control (0–10V DC input, optional): For precision micro-airflow adjustment (e.g., residential closet dehumidifier ventilation, small office cubicle fresh air control), enabling damper adjustment with ±4% positioning accuracy—sufficient for non-critical air quality or humidity maintenance. It includes optional analog position feedback (0–10V DC) for damper status monitoring, compatible with residential smart thermostats or small commercial basic ventilation controllers. Ultra-Compact & Quiet Build: Engineered with a flame-retardant plastic housing (UL94 V-0) and an ultra-lightweight design of 0.18 kg (0.4 lbs), suitable for direct micro-damper mounting (via mini clip-on brackets) or installation in extremely tight spaces (e.g., exhaust fan enclosures, mini-ventilation ducts). The housing features IP44 protection (dust-resistant, splash-proof), making it compatible with indoor residential and small commercial environments (e.g., apartments, small offices). Safety & Reliability Features: Built with essential safeguards for micro-scale operation: Overthrust protection: Automatically stops the motor if thrust exceeds 80 N (e.g., damper jamming from dust buildup or duct pressure), avoiding damage to the tiny damper or actuator. Thermal overload protection: Shuts down the motor in case of overheating (e.g., prolonged continuous operation), extending component lifespan and preventing fire risks. 24V low-voltage safety: Designed for 24V AC (50/60 Hz) input with ±10% voltage tolerance, eliminating electrical hazards in occupied spaces. Simplified Installation: Designed for tool-free plug-and-play setup—works with Siemens residential controllers (e.g., Desigo Home) and third-party devices via standard 24V on/off or 0–10V signals. Its mini clip-on brackets fit most micro-damper sizes, and color-coded wiring terminals reduce installation time to under 5 minutes for most applications. Typical Applications SIEMENS Actuator SKP25.003E2 is engineered for ultra-light-duty linear control of micro-dampers—ideal for scenarios needing 80 N thrust, 10 mm stroke, and 24V power in residential or small commercial micro-ventilation systems. Key use cases include: Residential Bathroom Exhaust Dampers: Controlling tiny dampers in residential bathroom exhaust fans. On/off control syncs with fan operation to prevent cold air infiltration, while ultra-compact size fits fan enclosures—complying with EN 13141-6 (residential ventilation) and EN 60335 (appliance safety). Small Commercial Mini-Ventilation Units: Regulating dampers in small commercial micro-ventilation systems (e.g., office cubicle fresh air units, retail display case dehumidification vents). Optional modulating control adjusts airflow to match occupancy needs, and IP44 protection withstands indoor moisture—complying with EN 13141-6 (non-residential ventilation) and ASHRAE 62.1 (indoor air quality). Residential Closet/Storage Dehumidifier Dampers: Adjusting dampers in residential closet or storage room dehumidifier systems. Simple on/off control maintains low humidity, and quiet operation avoids disturbance—complying with EN 13141-6 (residential ventilation) and local building codes. Small Appliance Ventilation Dampers: Controlling dampers in small appliance ventilation (e.g., countertop air purifiers, compact dehumidifiers). Ultra-compact design fits appliance casings, and 24V power integrates with appliance control systems—complying with EN 15502 (appliance standards) and IEC 60335 (safety)
