Product description

This full automatic compensated voltage stabilizer is designed to stabilize AC voltage , It adopts principle of superposition and compensating method, when the power grid's voltage fluctuates or the fluctuates caused by load variation, it can automatically maintain the satiability of output voltage.
We have two type of full automatic compensated voltage stabilizer :DBW single phase compensated voltage stabilizer and SBW three phase compensated voltage stabilizer.The capacity is from 10KVA to 2400KVA.

Basic Data:
Input: AC Power with Voltages of Various Countries
Output: AC Current, Voltage, According to Customers Requirements
Power: from 10KVA to 2400KVA
Frequency: 50-60Hz
Phase:single phase and three phase
Mode of control: Analog Controlled Circuit
Parameter Setting: Adjust by potentiometer
Indication: to show the voltage and current by pointer type meter

Main Features:
This series products has many advantage such as large capacity,high efficiency,no additional waveform distortion,adjust the voltage steady,the strong ability of impact resistance,suit any load,working continuously,auto/manual transfer,using easily,operational reliability and so on.

Operating environment
1)Temp.:The ambient temperature can not over +40℃。
2)Altitude: Mounting location can not exceed the altitude of 2000m
3)Relative humidity: Maximum 90%
4)The site not attack by rain and snow
5)The medium which no explosion danger, no corroding metal, no electrical breakdown

Testing Items:
