Reversible with built-in switch. The LF series provides 95 of rotation and is provided with a graduated position indicator showing 0 to 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.
Visual indicator, 0 to 95 0 is spring return position. Add to a new shopping list. Actuator Customization characters remaining Quantity: Power consumption is reduced in holding mode. Actuator Customization characters remaining.
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 LF series actuators provide true spring return operation for reliable fail-safe application and positive close-off on air tight dampers.
The switching function is adjustable between 0 and Personalization If needed, use the space below to type in any additional actuator configuration required for your order: A 2 to 10 VDC feedback signal is provided for position indication or master-slave applications. The actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches. Quantity Discounts Quantity Amount 5 to For proportional modulation of dampers in HVAC systems.
