Product Summary:

The YIY-AVC is an inverter based system that protects sensitive industrial and commercial loads from voltage disturbances.Providing fast, accurate voltage sag and surge correction as well as continuous voltage regulation and load voltage compensation.
The YIY-AVC has been optimally designed to provide equipment immunity from power quality events on the supply network.

Working Principle:

The YIY-AVC consists of two converters that are not on the current path between the load and the utility. Instead, the corrective voltage injection is achieved by means of a transformer winding between the utility and the sensitive load. This configuration results in a very efficient and effective method to provide voltage correction with reduced risk of negative impacts on the load. The YIY-AVC requires no batteries as it draws the additional energy required during sag to make up the correction voltage from the utility supply. With no ongoing maintenance costs typically associated with batteries the cost of ownership for YIY-AVC systems is very small. Furthermore, the YIY-AVC contains a redundant internal bypass system that, in the event of overload or internal fault condition, ensures that the load is continued to be supplied from the utility.
