1. DBW-W series single-phase intelligent non-contact AC voltage regulator is a new generation of intelligent fast energy-saving voltage regulator developed by EECTECH to introduce and absorb foreign advanced technology and meet the special needs of long power supply distance and frequent input voltage abrupt change. power supply. The central control system of the voltage regulator adopts intelligent control of the single-chip microcomputer and is equipped with digital display, which highlights the safety, stability, energy saving and humanized human-machine interface of the device. Compared with the traditional DBW series single-phase compensation regulator and SVC high-precision voltage regulator, it has three significant advantages: intelligent control and digital display, fast voltage regulation and quiet energy saving.
2. DBW-W series single-phase intelligent non-contact AC voltage regulator is especially suitable for use in long-distance power supply and power supply environment with frequent input voltage changes. It is a traditional DBW series single-phase compensation regulator and SVC high-precision stability. A comprehensive replacement for presses.
3. DBW-W series single-phase intelligent non-contact AC voltage regulator is generally used indoors, the normal use conditions are:
1), ambient temperature: -10 ° C - +45 ° C
2), altitude: <1000M
3) Relative humidity: 20%-90%
4) No gas, steam, chemical deposits, dust, dirt and other explosive and corrosive media that seriously affect the insulation of the regulator.
5) There is no serious vibration or bumps in the installation site.
