Air damper actuators

GMA..1

Rotary version with spring return, AC 24 V / DC 24…48 V / AC 230 V

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.

This data sheet provides a brief overview of these actuators. Please refer to the

technical basics in CM2Z4614en for a detailed description as well as information on

safety, engineering notes, mounting and commissioning.

Use

• For damper areas up to 1.5 m

, 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).
