Electric Actuators are reversing proportional motors used to operate dampers or valves in Electric Modulating Circuits. Electric actuators are designed to meet the requirement of damper control, valve control applications where it is generally required to drive the load through less than one complete revolution either direction and to stop instantaneously at any point of the stroke. Such devices, sometimes also called as Modulating Motors are extensively used for Air-Conditioning, Boiler applications.
FEATURES:
1. These are with line voltage or low voltage motors.
2. Stroke is fixed at 900, 1600, or 2700 and is also field adjustable.
3. Models for two-position (ON-OFF) control, fitted with feed back potentiometer and proportional control in conjunction with extend control can be supplied.
4. Rated for -400C to 550C.
5. Available with internal cam adjusted auxiliary switches.
SPECIFICATIONS:
1. Supply Voltage : 24, 110, 230 VAC, 50/ 60Hz, 1 .
2. Power Consumption : 20 Watts.
3. Stroke : Factory set at 900, 1600 or 2700. (Field adjustable).
4. Auxiliary Switch (Optional) : 2.5A, 250V, 50Hz, NO or NC. (Operated at only
one fixed point).
5. Feedback Potentiometer : 135 standard matched to stroke angle of either
900, 1600 or 2700. (The maximum permitted
power dissipation for feedback potentiometer is
1W for 900, 1.5W for 1600, and 2W for 2700
stroke angle).
