KVEC Energy Controllers utilize a unique patent-pending system that allows precise adjustment of power factor in an inductive motor. It is this precision that determines how efficiently a motor can operate. A precisely adjusted motor will use less energy, and its operating temperature will be lower, extending its useable life.
The reason we developed this adjustable system is that not all inductive motors are created equal. Even brand new, out-of-the-box motors, from the same maker, with identical specifications, can have quite different power factor test results. Imprecise corrections may be too little, or too much.
Under- correcting will not provide the best savings, in amps and dollars, and operating temperature. Over-correcting can cause amperage flows to increase rather than decrease, costing more money for energy, and possibly damaging equipment.
In addition, all KVEC Variable units are equipped with TVSS Surge Protectors, which direct, dangerous overvoltage surges harmlessly to ground, decreasing the likelihood of damage. Capacitors alone cannot do this. (more)

KVEC for Residential Applications

KVEC Energy Controllers are usually installed at the home's electrical panel. They are adjusted to compensate for such things as seasonal variations in current demands.

An important warning: One size does not fit all

Buying a capacitor-based energy controller on the internet and installing it yourself is unlikely to provide the results you were promised.

Your KVEC can be Power Factor with TVSS, or TVSS with Power Factor

What's important about this? The unit can be adjusted to best do what you need most.

An important warning about surge protection

Energy controllers, including our own KVEC units, utilize devices called capacitors to briefly store electrical energy .

For that reason, some marketers of capacitor-based energy controllers claim that they provide protection for overvoltage (power surge) events. While this is true, the protection they offer is very limited by the ability of the capacitors to absorb volts.

 This is usually only about 10% more than the stated rating of the capacitor before they blow their internal fuses and release the energy into your system.

 A typical transient voltage surge in your system can be thousands of amps - far more than any capacitor can absorb, even for an instant.

Capacitors simply cannot absorb enough electrical energy to protect your system and its expensive components. Because they are not wired to ground, they cannot protect themselves – or anything else.

Energy Management Partners equips our KVEC Energy Controllers with TVSS – Transient Voltage Suppression Systems – which are specifically designed and wired to automatically capture voltage spikes and route them to ground, where they are dissipated.

The TVSS units in KVEC will protect your system from surges up to 40,000 amps, depending on the size of the KVEC unit.  

So don’t put all your faith in capacitors to protect your expensive equipment from transient power surges. Capacitors are not intended to be surge protectors.
