For proportional modulation of dampers in HVAC systems.

Actuator sizing should be done in accordance with the damper manufacturers specifications. A crank arm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft.


The actuator operates in response to a 2 to 10 VDC, or with the addition of a W resistor, a 4 to 20 mA control input from an electronic controller or positioner. A 2 to 10 VDC feedback signal is provided for position indication or master-slave applications.


The LF series provides 95 of rotation and is provided with a graduated position indicator showing 0 to The microprocessor provides the intelligence to the ASIC to provide a constant rotation rate and to know the actuators exact fail-safe position.

The ASIC monitors and controls the brushless DC motors rotation and provides a digital rotation sensing function to prevent damage to the actuator in a stall condition. The actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches.

Power consumption is reduced in holding mode. Welcomeyou have 0 items in your cart Sign-up View Cart Checkout.
