#Company Introduction Digital Free Voltage Regulator is implemented with DSP chip by using All IGBT PWN Control and Driver. It is also Double Conversion System transferring bi-directional energy . It keeps rated output without relying on battery in the region where AC is especially significant distortion or extreme fluctuation in the voltage of the battery. By applying Digital-Free Voltage Regulator we can not only reduce frequency of using battery but also preserve battery life and performance in case of extended power outage. It leads to benefit of operating costs and battery replacement costs such as UPS . When the system voltage is applied, input operation frequency of system is determined 60Hz or 50Hz by automatic identification.All of functions are on software and variables related to the system will be memorized by setting to keypad. Double Conversion Module of this system is designed with 20 percent of the load capacity for cost savings. The input voltage and current make the same phase so that it has same factor with load factor equally. Plus, the size of it can be smaller up to 1/3 of it as it is producing in large quantity.
