DBW-W series single-phase intelligent contactless AC voltage regulator is a new generation of intelligent fast energy-saving voltage regulator power supply developed and produced by our company to meet the special needs of long power supply distance and frequent sudden changes in input voltage in combination with our country's national conditions. The central control system of the voltage regulator adopts the intelligent control of the microcontroller and is equipped with a digital display, which highlights the safety, stability, energy saving and user-friendly human-machine interface of the equipment. Compared with the traditional DBW series single-phase compensated voltage regulator and SVC high-precision voltage regulator, it has three significant advantages: intelligent control and digital display, fast voltage regulation, and silent energy saving. DBW-W series single-phase intelligent contactless AC regulators are especially suitable for long-distance power supply and frequent input voltage sudden changes in power supply environments, and are a comprehensive replacement for traditional DBW series single-phase compensated voltage regulators and SVC high-precision regulators. DBW-W series single-phase intelligent contactless AC regulator is generally used indoors, and the normal use conditions are: 1. Ambient temperature: -10°C—+45°C 2. Altitude: <1000M 3. Relative humidity: 20%-90% 4. There are no gases, steam, chemical deposits, dust, dirt and other explosive and corrosive media that seriously affect the insulation of the voltage regulator. 5. There is no serious vibration or bump in the installation site.
