08-032020Install regulator can save more electricity?We have a customer is do processing of stainless steel material, there are mainly several 7 kw spot welding machine, because the voltage is not stable in our company purchasing a AC Automatic Voltage Regulator (AVR), used a month later, found that since electricity saving 3000 yuan, thank you call outside also consulting a problem, voltage regulator is how power than before installing stabilizer also save electricity? Yes, everyone thinks is stable voltage stabilizer, don't know can also bring power saving function, voltage regulator is the power consumption to a certain extent, but the non-contact voltage regulator is no mechanical no carbon brush more power saving than traditional voltage regulator, if the voltage stability, its power consumption is negligible, in fact, voltage and current, like the inside of the pipe water, water pressure, the more urgent, we usually wash hands, we don't have to open the tap is very big, also do not need very urgent
