 PURPOSE OF USE
This product is an automatic power factor controller for three phase to control the closing amount of power condenser automatically.
Following purposes can be achieved w/ this product.
>> Electricity charges can be saved by power factor discount.
>> Labor saving by work reduction of power factor monitoring/adjustment.
>> Effective use of facility capacity can be realized by power loss reduction.
>> Equipment life can be extended by stabilizing circuit voltage.
FEATURES
