May 20, 2021 Damper Actuators
Damper actuators are powered devices that are used to operate a damper and adjust the flow of air and smoke. There are two basic types: electric and pneumatic. Electric damper actuators differ in terms of output. Choices include 0 to 12 VDC, 2 to 10 VDC, and 4 - 20 mA. Products with features such as low-power consumption, direct action, reverse action and thermal protection are commonly available. Pneumatic
damper actuators have a start point that is measured in pounds per square inch (psi). The span is direct function of a feedback spring. In some products, the spring is designed to provide equal force on both the power and return strokes. General damper actuators and specialized fire and smoke damper actuators are also available.
Damper actuators carry specifications for shaft diameter and position feedback. Shaft diameter is usually measured in inches, and indicates the diameter of either the output shaft or the table. Damper actuators with angular position-feedback incorporate devices such as encoders or potentiometers. Encoders are devices that are used to change a signal or data into code. Types include linear, digital, incremental rotary, and absolute rotary. Potentiometers are passive electronic components that oppose the flow of either alternating current (AC) or direct current (DC). Types for damper actuators include linear and digital.
