The LF series actuators provide true spring return operation for reliable fail-safe
application and positive close-off on air tight dampers. The spring return system
provides consistent torque to the damper with, and without, power applied to the
actuator.
The LF series provides 95° of rotation and is provided with a graduated position
indicator showing 0 to 95°.
The LF24-3 (-S) US uses a brushless DC motor which is controlled by an Application
Specific Integrated Circuit (ASIC) and a microprocessor. The microprocessor provides
the intelligence to the ASIC to provide a constant rotation rate. The ASIC monitors and
controls the brushless DC motor’s 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.
