Siemens Building Technology GDE166.1P Actuator Refrigerant The AK series sheave featuresThe Siemens GDE166. 1P is a high performance OpenAir damper actuator designed for precise modulating control in HVAC systems. Operating on a 24V AC DC power supply, this non spring return actuator delivers 44 lb in (5 Nm) of torque, making it a reliable choice for constant or variable air volume (VAV) applications. It accepts a standard 0 10 VDC control signal and provides a proportional 0 10 VDC feedback signal for real time position monitoring.
