German Omar electric actuator - agents and distributors in China 
 Technical parameters of AUMA NORM 
 According to the tender requirements, we choose the configuration of the actuator and performance with the following parameters: 
 Power supply: 380V ± 20%, 50Hz ± 1%, 3Ph, negative power supply voltage falls below the limits of the actuator to start properly, and ensure their full travel itinerary change is not greater than 1.5%. 
 Electric actuator working system: an hour to allow the number to 1,200 connected. 
 Motor: three-phase squirrel-cage induction motor, insulation class F, three-phase winding in series with each phase are overheating protection switch, the protection action temperature of 140 degrees Celsius. Motor with high starting torque with low inertia. 
 With simple structure, reliable bi-directional limit switches and torque switches, and in the middle can be arbitrarily set also provides the location of the two signal contacts. Each of the switches are independent of one normally open and one normally closed contact. No public contacts between the side independent of each other. Contact capacity 250VAC, 5A; mechanical life of more than two million times. 
 Regulator-type actuator with a 4 ~ 20 mA feedback device. Its maximum load is 600 W. 
 Self-locking worm gear and worm drive mechanism to prevent idle away. 
 Independent of the hand wheel, stop at any time electric hand wheel operation can be switched, and remained self-locking feature at this time. Power up, automatically restore power. 
 Actuator travel time: see technical data table. 
 Operating Temperature: Standard electric actuator operating temperature range is -30 ° C ~ +80 ° C. 10 ° C ambient temperature change when the change of the actuator stroke is not greater than 1.5% of the whole trip. 
 Relative Humidity: ￡ 95%. 
 Protection class: IP 67, submersible type. (Actuators can work in an environment of water meters in the next 30 minutes.) 
 Protection with the torque, the torque and thrust on the basis of the nominal value of not less than ± 20% are adjustable margin. Travel with adjustable ± 10% margin. Travel time can be adjusted. 
 Appearance: the outer layer of mica for the corrosion of iron infiltration, smooth panels and nameplates. 
 Self-tuning machine chamber heater to prevent condensation inside the actuator.
