DBW/SBW single phase and Three Phase Voltage Stabilizer (hereafter call voltage stabilizer) is a contact adjustable stabilizer, application when outside electricity power fluctuation or load power all time difference rebellious voltage fluctuation, this Three Phase Voltage Stabilizer can automatic keep output voltage stabilization, this series products compare with other stabilizer have as follow feature: have big capacity, efficiency very high, non-lack fidelity in wave distortion, the voltage adjustable balance, self-cooling and successively working for long period and long service time, can endure instantaneous over-load,as well as transferring between manual control and automatic control system, besides it is provided with protection over-voltage,over-load(over-current),lack phase or phase fail, phase sequence protect and mechanical breakdown automatic protect, small volume, light weight, convenient installation and reliable running and so on.
Three Phase Power Voltage Stabilizer Widely used in electromechanical equipment, metal processing equipment, production line, construction device, excvavtor for gold mine, post and telecommunications, department stores, elevators, hospitals equipment, schools, printing machine, securities and other occasions where all need normally voltage to ensure, such as workshop mines medium enterprises, some of the important equipement and computer power and support where need voltage stabilization.
Three Phase Voltage Stabilizer Meet the standard: JB/T 8749.8, Q/ZT431.

1. Three Phase Voltage Stabilizer Ambient temperature: -10°C~+40°C.
2. The altitude does not exceed 1000 meters.
3. Relative humidity: not more than 90%.
4. The installation site should be free of gas vapor, chemical deposits, dust, dirt, and other explosive and aggressive media that can seriously affect the voltage stabilizer's insulation.
5. The installation site should be free of severe vibration or bumps.
6. The special use conditions that do not meet the above requirements shall be determined through consultation between the user and the company.

Remarks: 1. SBW Three Phase Power Voltage Stabilizer (380V/220V), (380V/200V) and (220V/220V) products can be customized.
2. Three Phase  Voltage Stabilizer that exceed the parameters and technical performance in the above table can be negotiated and customized.
For example: voltage output 400V, voltage output three-phase 220V, voltage regulator range ± 30% can be customized.

The adoption of the "Mains Direct New Technology" has reduced the number of AC contactors and improved the reliability of the regulator.
Output over-voltage protection and alarm function: In the regulation state, when the input voltage exceeds the upper limit of the regulator input voltage range (three-phase: 456V, single-phase: 264V) and reaches a certain value or the output voltage of the regulator higher than the specified value caused by other causes, the regulator cuts off the output power and alarms. After the input and output voltages fall within the limits, the regulator automatically returns to normal.
Three Phase Power Voltage Stabilizer With self-recovery function: When the power outage of the power grid is restored, the regulator can be automatically restored power supply.
Three Phase Power Voltage Stabilizer With on delay function: In the regulation state, press the start button, the voltage regulator will only have voltage output after self-adjustment to a stable value (a few seconds).

Selection method:
The regulator capacity can be calculated by the following formula: S=PS'/cosφ. Among them: S-actually requires regulator capacity, P-load power, S'-safety factor, and cos-load power factor.
Power factor:
1. Purely resistance load: The power factor is 1 (such as resistance wire, electric furnace, etc.).
2. Inductive load: The power factor is generally 0.6~0.8 (such as elevators, air conditioners, and motor equipment).
3. Capacitive load: The power factor is generally 0.6~0.8 (such as computer room, radio and television, etc.)
4. Comprehensive load: The power factor is generally 0.6~0.7 (such as factories, hotels and comprehensive load of household appliances).
Safety factor
In inductive capacitive load environment, when selecting the model, the large startup current of the load should also be taken into account, which has an impact on the regulator. So 1.5 to 3 times the safety factor should be taken. The safety factor should be selected according to the load conditions. generally according to the low load equipment, large power, long work or repeated short time work (frequent start), and large values ​​when no additional start-up equipment is used, otherwise, take a small value.
The input and output circuits of this three-phase product are three-phase four-wire system wiring and must be connected to the zero line.
When three-phase power supply is used for single-phase applications or three-phase applications, the maximum output per phase is one-third of the nominal capacity of the entire machine.
If the user has any special requirements, please give additional instructions, TAIXI Electric can design and produce.
