Siemens Building Technology SAS81.03U Actuator
The Siemens Building Technology SAS81.03U Actuator is a robust, non-spring return (NSR) electromotoric actuator designed for precise 3-position floating control. Engineered for HVACR professionals, this unit operates on 24V AC/DC power and is primarily used with Powermite 599 MT Series terminal unit valves featuring a 5.5 mm (7/32-inch) stroke. With a 400 N positioning force and a rapid 30-second run time, it provides efficient drive action for 2-port and 3-port valves in heating and ventilation systems. The manual-positioning knob allows for field adjustments and position fixing without power, while the IP54 protection rating ensures durability in demanding environments. For technicians upgrading legacy systems, this electronic valve actuator is compatible with older Landis & Gyr valves when paired with an ASK30 adapter. The terminal block design simplifies field replacement, and the integrated status LED offers immediate feedback on operational health, which is critical for streamlining service calls and ensuring system uptime.
Key Benefits- Efficient Field Installation: Direct mounting to Powermite 599 MT Series valves eliminates the need for complex mounting linkages or time-consuming adjustments.
- Precise 3-Position Control: Optimized for floating control signals, providing stable and repeatable valve positioning for improved climate stability.
- Manual Override Capability: Features a top-mounted manual adjuster, allowing contractors to set valve position during power outages or initial commissioning.
- High Positioning Force: Delivering 400 N of force, ensure reliable shutoff and operation across a wide range of medium temperatures up to 130°C.
- Versatile Compatibility: Native support for Siemens SAS series valves and adaptable to various legacy configurations with standard accessories.
Is the SAS81.03U a spring-return actuator?
No, this model is a non-spring return (NSR) actuator, meaning it will stay in its last position if power is lost (fail-in-place). If your application requires a fail-safe position, consider the SAS81.33U variant.
Can I use this with a 24V DC power source?
Yes, the SAS81.03U is designed for dual-voltage flexibility and can be powered by either 24V AC or 24V DC supplies.
What is the difference between this and the SAS61 series?
The SAS81 series utilizes 3-position floating control, whereas the SAS61 series is designed for 0-10V or 4-20mA modulating control signals. Ensure your controller output matches the actuator's input requirements.
