How Does the Power Demand Controller Work?
You may not realize it, but in each home there are at least 20 home appliances that contain a motor in it. Some of these include: garage door opener, plasma television, garbage disposal, air conditioner, vacuum cleaner, Jacuzzis, and pool. If you have a workshop, most of the heavy machinery has motors in them. Every time you turn on these machines, the motor draws a significant amount of power causing energy spikes. Every one of those spikes is measured and charged by your power company even if you may not be using that much energy. The NES 2400 optimizes the power factor of your home, it absorbs these energy spikes and store them in the industrial sized capacitors therefore the power company cannot measure it. The power company will only see clean and consistent energy reading causing your bills to be lowered by 15-25%.

Power Factor

The power factor of an  AC electric power system is defined as the ratio of the real power lowing to the load to the  apparent power and is a number between 0 and 1 (frequently expressed as a percentage, e.g. 0.5 pf = 50% pf). Real  power is the capacity of the circuit for performing work in a particular time. Apparent power is the product of the current and voltage of the circuit. Due to energy stored in the load and returned to the source, or due to a non-linear load that distorts the wave shape of the current drawn from the source, the apparent power can be greater than the real power.

In an electric power system, a load with low power factor draws more current than a load with a high power factor for the same amount of useful power transferred. The higher currents increase the energy lost in the distribution system, and require larger wires and other equipment. Because of the costs of larger equipment and wasted energy, electrical utilities will usually charge a higher cost to industrial or commercial customers where there is a low power factor.

Linear loads with low power factor (such as  induction motors) can be corrected with a passive network of capacitors  or inductors . Non-linear loads, such as rectifiers, distort the current drawn from the system. In such cases, active power factor correction is used to counteract the distortion and raise power factor. The devices for correction of power factor may be at a central substation, or spread out over a distribution system, or built into power-consuming equipment
 

Surge protector
The NES 2400 protects the homes from power surges by acting as a buffer that will reduce electrical surges that are caused by factors either outside of the home or from within the home. Your home is protected from damaged transformers or electrical lines caused by either the weather or accidents outside of your home. There are hundreds of electrical surges that enter your home everyday. This will provide the first line of defense for your home appliances, especially important if you have computers at home.
 

Does the Power Demand Controller work in any home?
The unit is installed next to your circuit breaker panels. Therefore, it will work in any home as long as your breaker panel has breaker switches and not the screw-in fuse type.
 

How much can I expect to save per month by using the Power Demand Controller?
There are a variety of contributing factors that will affect how much you can save including the number of inductive motors you have in your home, the amount you are paying per kilowatt-hour, and the size and the number of people living in your home. The average savings is about 15-20%.
 

How long will it take for the Power Demand Controller to pay for itself?
As little as 3-4 years depending on your individual home consumptions. Normally the Commercial units recover investment sooner because of the high volume of consumption.
 

Is the Power Demand Controller easy to install?
We would advise having an electrician to have the NES 2400 installed. Every Power Demand Controller comes with installation instructions that are easy to follow.
 

Is the Power Demand Controller Unit Warranted? Is there a “Money Back Guarantee”?
It is warranted for 5 years full replacement. If you do not notice satisfying savings within 60 days, you can call us for instructions on how to return the unit for the full refund of the purchased price. We are not responsible for the installation cost.
