Actuators for dampers (with spring return)
AMD 413, 413 AS, AMD 423, 423 AS
Description AMD actuators are used for the regulation of
air dampers of 90° angle of rotation to be used
in heating, ventilation and air conditioning
applications (HVAC).
Features:
• Spring return function
• Manual operation
• Rotation direction selection by switch
• Adjustable rotation angle by mechanical end
stop min 35°.
• Position indication
• Overload protection
• Direct mounting with universal spindle clamp
• Anti-rotation strap for preventing actuator
from rotating
• Maintenance free

BU+BN (1+2) and a reference signal Y to BK (3) of
0(2)…10VDC, moves the actuator to its specied
position. The actual damper position 0…100%
is a feedback signal U for example to share the
signal with other actuators. If the power supply is
interrupted the actuator is moving to position 0

Through connecting the power supply to BU+BN
(1+2), the actuator moves to position 1 while the
pre-tensioned spring is wound up the same time.
If the power supply is interrupted the actuator is
moving back to position 0 by the spring power.

Direct mounting Simple direct mounting on the damper spindle
with a universal spindle clamp, supplied with an
anti-rotation strap to prevent the actuator from
rotating.
Manual operation The actuator can be operated only manually
while the power supply is o. The supplied lever
is to open and lock the damper position. The lock
stays until the power supply is put on.
