Damper Actuator 20NM

SDF series of damper actuator is a kind of universal type and direct-coupled quarter turn electric actuators, specialized designed for the dampers inside the HVAC system. It can make direct installation to the circular shaft, square shaft or abnormal shaft, common adjustment 90° , maximum to 96° , also with tight structure, angle of rotation use 3° As a increment, torque includes: 5 Nm, 10 Nm, 20 Nm, 40 Nm, adapt to dampers with different areas. Under the controlling of electri signal from the control system (Open-close, 3-point, DC0(2)-10Vor 4-20mA), output the torque of 5-40Nm, it can make the controlled objects rotate 0-90° , and output feedback signal of the corresponding position according to the requirements, which display the angle of rotation or directly control the working of another actuators, Nominal voltage AC/DC24V and AC100...240V optional. Adapt to air damper controlling with CAV or VAV.
