This Electric Controller is an advanced full electronic control devices which designed to replace three-phase autotransformer, can be used in resistance, inductive load and to control various electric motor.

1. The Electric Controller is used in many paper mills, color printing factory, dyeing and weaving mill, electric wire and cable factory, the processing, metal foils processing plant etc.
2. During the involution processing, deal with something such as paper, cloth, lines, metal foils, Film material and products, these all need to use manual tension control for the rewind and unwind.

Electric motor controller is small, light, efficient, little heat and energy conservation (Being tested, it can save energy more than 17%). And it is easy to be installed and repaired.
Compared with three-phase autotransformer, this controller's startup performance is good, because it is installed with electron regulation, zero contact erosion and voltage regulating balance and with good starting performance.

The scope of application:
1. Environment temperature: -25 centigrade to +55 centigrade
2. Relative humidity: Less than 85%(20 centigrade plus-minus 5 centigrade)
3. Install at the place without significant shock and vibration.
4. Voltage: Three phase 380V, AC
5. Frequency: 50-60Hz
