(dbw.sbw single-phase and three-phase full-automatic compensation type power regulators SBW, DBW series single-phase and three-phase full-automatic compensation type power regulators are voltage regulators introduced and absorbed by our company from Western Europe, and are designed to stabilize AC voltage according to China's national conditions. When the external power supply network voltage fluctuation or load change causes voltage fluctuation, the voltage regulator (regulated power supply) can automatically maintain the stability of the output voltage. Compared with other types of voltage regulators, the regulator (stabilized power supply) has the advantages of large capacity, high efficiency, no wave opening distortion, voltage regulation balance, etc. the regulator (stabilized power supply) is suitable for wide load and can be overloaded instantaneously. The regulator (stabilized power supply) can work continuously for a long time, and can be manually / automatically switched at will. The regulator (stabilized power supply) is equipped with over-voltage, over-current, phase loss and phase It has the advantages of small volume, light weight, convenient installation and reliable operation.
(dbw.sbw single and three-phase full automatic compensation power regulator) the voltage regulator (regulated power supply) is widely used in large-scale mechanical and electrical equipment, metal processing equipment, production line, construction engineering equipment, elevator, medical equipment, embroidery and textile equipment, air conditioning, radio and television, household electricity and lighting in the fields of industry, agriculture, transportation, post and telecommunications, military, railway, scientific research and culture, etc Places where voltage stabilization is required. SBW and DBW series regulators should be used indoors. The normal operation conditions of the voltage regulator (regulated power supply) are as follows:
● ambient temperature: - 15 ℃ ~ 40 ℃
Altitude: < 1000M
Relative humidity: < 90%
There shall be no gas, steam, chemical deposition, dust, dirt and other explosive and corrosive media that seriously affect the insulation of voltage stabilizer.
There is no serious vibration or turbulence in the installation site.
