Hises has been enjoying reputation not only in Korea but also in overseas markets as a quality manufacturer of electric power saver having enhanced technology retaining 7 patents and sole approval from the government for almost a decade since 2003. Manufacturing is done all in Korea and Q/C is very carefully managed. The saver can control proper voltage & amperage according to type of loads and load factor which obtained principle patent "self mutual induction" automatically. It also has lots of protections & safety functions, remarkable reduction in power consumption up to 15%, as well. The lifespan of load machinery can be extended about 20% by voltage regulation & increasing efficiency and power factor of loads through controlling imbalance among 3-phase.
