4Nm SPRING RETURN ROTARY ACTUATORS

Invensys Spring Return Actuators have a rotary output for direct

coupling to air dampers. Models are available for on/off operation from

230Vac or 24Vac power supplies and 24Vac Floating Point Control.

There is also a 2-10Vdc input version that is fully modulating.

A special feature of the design is that mounting brackets, universal

joints and linking rods are not required for normal damper applications,

thus reducing installation and commissioning time.

FEATURES

• Direct coupling to all normal dampers without mounting

brackets or linkage kits - saves site time

• Universal clamp provides direct mounting to damper shafts up

to 15mm diameter or up to 13mm square (AM-710 accessory

clamp required when mounting actuators to shafts up to 19mm

diameter or 13mm square)

• Case to IP 54

• Clockwise and Counterclockwise rotation available,

determined by Left or Right Hand mounting

• Spring tensions whilst the damper is being operated

• Positive spring return operation, for example under power

failure

• Provides 95° of rotation; rotation limiting available

• Visual position indicator

• MX41-7043 Series actuators can be gang mounted to

accommodate high torque requirements

• Optional built-in auxiliary switches to provide for interfacing or

switching

• Cable Gland and Blanking plugs supplied fitted

• MS4X-7XXX Series provided with Left/Right switch for selection

of direct or reverse action control mode.

Notes:

Using Invensys damper actuators

The actuators listed in this data sheet are intended for the operation of

air dampers in HVAC systems.

Torque requirements

When calculating the torque required to operate dampers, it is

essential to take into account all the data supplied by the damper

manufacturer concerning cross sectional area, design, mounting and

air flow conditions.
