Direction of Rotation fail-safe.
You may not enter more than characters for ‘Actuator Customization’. Personalization If needed, use the space lff24 to type in any additional actuator configuration required for your order: Power consumption is reduced in holding mode.
The spring return system provides consistent torque to the damper with, and without, power applied to the actuator.
The switching function is adjustable between 0 and Actuator Customization characters remaining Quantity: Electronic throughout beli,o to 95 rotation. Add to a new shopping list. Welcomeyou have 0 items in your cart Sign-up View Cart Checkout.
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. Reversible with built-in switch. Actuator Customization characters remaining. The actuator may be stalled anywhere in its normal rotation without the need of mechanical end switches.
The LF series actuators provide true spring return operation for reliable fail-safe application and positive close-off on air tight dampers.
The microprocessor provides the intelligence of24 the ASIC to provide a constant rotation rate and to know the actuators exact fail-safe position.
