DBW, SBW series single-phase automatic compensation power regulator applies automatically to maintain the stability of the output voltage when the external power supply network voltage fluctuations or load changes caused by voltage fluctuations. This series of products compared with other types of regulator, with a large capacity, high efficiency, no waveform distortion, stable voltage regulation, etc., widely applicable load, able to withstand transient overload, long-term continuous work, manual / automatic switch over voltage protection, lack of phase, phase sequence protection and mechanical failure of automatic protection, this machine is small, light weight, easy installation and reliable operation, etc. (Fractions significant instrumented two).
Use the occasion
Widely used in all the needs of the normal voltage of Posts and Telecommunications, a mall, elevators, hospitals, schools, printing, textile, securities guaranteed occasions and large and medium-sized industrial and mining enterprises workshop, part of the power supply and critical equipment and ancillary.
