The RM-12-3P Controller is for compensation of Balanced and Unbalanced is a ultimate solution for Compensation of Unbalanced Load. The compensation is realized by measuring the reactive power of the system through 3 current transformers from 3 phase. this series is a unique selection for Unbalanced load compensation
