4Nm Non Spring Return Damper Actuator

DA-004N024PX

The small electric damper actuator series have been developed to operate small and medium air damper in ventilation and air conditioning systems. The compact design makes this actuator highly versatile.

Applications:

• Constant or variable air volume installations for the control of HVAC dampers.

Features:

• DC 0(2)...10 V or 0(4)...20 mA with field-furnished 500 Ω resistor
• Load-independent running time
• Up to 5 actuators in parallel operation possible
• 1.2 M PVC Cable or Terminal block
• Simple direct-mounting with universal adapter for fitting on a 8-13 mm Ø round axis or on a 8-10 mm square shaft
• Selectable direction of rotation
• Manual release button
• Automatic shut-off at end position
• Devices meet CE requirements

8Nm Spring Return Damper Actuator - Proportional Control

DA-008S024Px Series

The 8Nm Spring Return electric damper-actuator series has been specially developed for the motorized operation of air dampers in air conditioning systems. The compact design and universal adapter fitted with limitation of rotation angle make this actuator highly versatile.

When the control signal is applied the actuator drives the damper to the operational position, while evenly tensioning the integrated spring. After a power failure the stored energy in the spring immediately brings the damper to the safety position. Manual operation is automatically cancelled when the actuator is in electrical operation.

Applications:

• Constant or variable air volume installations for the control of HVAC dampers.

Features:

• 0(2)..10 V or 0(4)..mA control signal
• Up to 5 actuators in parallel operation possible
• Electrical connection with halogen-free cable
• Simple direct mounting with universal adapter on Ø 8 mm to 16 mm shaft or 6 mm to 12 mm square shaft. An optional M9208- 600 Jackshaft Coupler Kit is available for 12 to 19 mm round shafts, or 10 mm to 14 mm square shafts
• Limitation of rotation angle
• Manual positioning with crank handle
• Two auxiliary switches, one adjustable

10Nm Non Spring Return Damper Actuator

DA-010N024UX

The DA-0010Sx Series Electric Non-Spring Return Actuators provide control of dampers in HVAC Systems for 10Nm rated torque.

These bidirectional actuators do not require a damper linkage and are easily installed on round shafts or square shafts.

An optional line voltage auxiliary switch kit can be field installed to indicate an end-stop position or perform switching functions within the selected rotation range.

Applications:

• Constant or variable air volume installations for the control of HVAC dampers.

Features:

• Automatic signal input detection model On/Off, Floating and Proportional increase availability at distributors and simplify retrofits.
• High speed actuator model allows applications in loop that require a quick response time.
• Optional auxiliary switch & potentiometer feedback provide line voltage capable single Pole Double-Throw (SPDT) switch and 140Ω, 1KΩ, 2KΩ or 10KΩ feedback potentiometric.
• Self-calibrating to adjust stroke, eliminating need of complex calibration procedure when adjusting stops.
• Electronic stall detection protects from overload at all angles of rotation. The actuator may be stalled anywhere in its rotation range without the need for mechanical end switches.
• Microprocessor-controlled brushless DC motor provides constant runtime independent of torque and increases life cycle by reducing wear.

20Nm Spring Return Damper Actuator - Proportional Control

DA-020S024Px Series

The 20Nm spring return electric damper-actuator series has been specially developed for the motorized operation of safety air dampers, (anti-icing) in air conditioning systems, smoke evacuation dampers and sealing dampers. The compact design and universal adapter fitted with limitation of rotation angle make this actuator highly versatile.

When the control signal is applied, the actuator drives the damper to the operational position, while evenly tensioning the integrated spring. After a power failure the stored energy in the spring immediately brings the damper to the safety position. Manual operation is automatically cancelled when the actuator is in electrical operation.
