LF120 US – Spring Return Fail-Safe

LF120 US – On/Off, Spring Return Fail-Safe, AC 120 V, Torque min. 35 in-lb (4 Nm), for control of air dampers.

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 actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches. Power consumption is reduced in holding mode. The actuator is double insulated so an electrical ground connection is not necessary.

Torque motor: 4 Nm (35 in-lb)

Angle of rotation: 95° max.
