Description
Siemens GDE146.1P Non-Spring-Return Damper Actuator
The Siemens GDE146.1P is a commercial-grade, non-spring-return (NSR) damper actuator engineered for reliable HVAC air-side control in building automation and mechanical systems. Rated at 44 lb-in of torque, it delivers the driving force needed to operate medium-to-large damper assemblies with precision and consistency. The 24V supply voltage makes it compatible with standard low-voltage control systems, and the 2-position/floating (2PT/FLT) control input provides flexible integration with a wide range of building automation controllers and thermostats.
Key Features
- Torque rating: 44 lb-in — suitable for medium-to-large commercial damper applications
- Non-spring-return (NSR) operation — damper holds position on power loss
- 2-Position / Floating (2PT/FLT) control signal for versatile system integration
- 24V AC/DC supply voltage — compatible with standard low-voltage BAS and HVAC controls
- Integrated auxiliary (AUX) switch for end-position feedback or interlocking
- Compact, direct-coupled design for simplified installation without linkage hardware
- Suitable for use with rectangular and round dampers in commercial HVAC systems
Application
The GDE146.1P is ideal for use in air handling units, VAV systems, economizer dampers, and other commercial HVAC applications where precise damper positioning and position feedback are required. Its non-spring-return design ensures the damper maintains its last commanded position during a power interruption, making it well-suited for applications where fail-in-place operation is preferred.
