| The Power-Save 1200 Reduces the Amount of Inductive Load in your environment and benefits include lowers electric bills and reduction of electricity by inductive loads. It also enhances capacity of the existing electrical system. A built in benefit is that it eliminates harmful power surges.
When capacitance is added to the load on your electrical panel, that capacitor begins to supply the KVA-R to the motor, which in turn helps the motor create the EMF. The motor no longer has to create electromagnetic flow, which cancels out the resistance line loss and heat dissipation.
The utility companies will no longer have to deliver as much amperage to fight through the resistance, and therefore your electric current decreases. Your home/business becomes more energy efficient. |
