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.

LF24-S US and LF120-S US incorporates a built-in auxiliary switch: 1 x SPdt, 6A (1.5A) @ 250 VAC, UL listed, adjustable 0° to 95°. meets cULus or UL and CSA requirements without the need of an electrical ground connection.

LF24-SR-E US actuators have built-in brushless DC motors which provide better accuracy and longer service life. The LF24-SR-E US actuators are designed with a unique non-symmetrical deadband. The actuator follows an increasing or decreasing control signal with a 80 mV resolution. If the signal changes in the opposite direction, the

allows the LF24- SR-E US to retrofit or replace Honeywell® M8405A actuators. A 2 to 10 VDC feedback signal is provided for position indication. The LF series actuators provide true spring return operation for reliable fail-safe application and positive close-off on air tight dampers.

For On/Off, fail-safe control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications. Control is On/Off from an auxiliary contact or a manual switch.
