General

Electronic motor driven actuators for two-position, three-position, and modulating control, nominal torque 7 Nm, with spring return, self-centering shaft adapter, mechanically adjustable span between 0...90°, prewired with 0.9 m long connection cables.

Type-specific variations with adjustable offset and span for the positioning signal, position indicator, feedback potentiometer and adjustable auxiliary switches for supplementary functions

Features

• For damper areas up to 1.5 m2, friction-dependent.
• In ventilation sections where the actuator must move to the zero position (emergency position) during power failure.
• For dampers having two actuators on the same damper shaft (tandem-mounted actuators or Powerpack).
