Products

Powerware's ferroresonant products are proven technology. In 1938, we were awarded the first patent for ferroresonant power conditioners: the constant voltage transformer. Since then, our technology has remained at the forefront of ferroresonant power conditioning.

Today, Powerware's ferroresonant power conditioners supply sinewave output, which is especially important for computer applications.

Every ferroresonant power conditioner is manufactured to exacting specifications and is subject to rigorous quality control.

The ferroresonant power conditioners protect equipment from all power problems, other than the complete loss of power. They excel at tightly regulating the voltage, providing superior noise attenuation and are ruggedly designed to withstand the harshest electrical environments. Possessing no moving parts, ferroresonant power conditioners are virtually maintenance free.

What is Ferroresonance?

Simply put, ferroresonance is the property of a transformer design in which the transformer contains two (2) separate magnetic paths with limited coupling between them.

The output contains a parallel resonant tank circuit and draws power from the primary to replace the power delivered to the load.

Note that "resonance" in ferroresonance is similar to that in linear circuits with series or parallel inductors and capacitors, where the impedance peaks at a particular frequency. In a non linear circuit, such as a ferroresonant transformer, "resonance" is used to Typical Model 200 or 210 Performance reduce the changes in supply voltage and provide more constant voltage to the load.

A magnetic device is non linear. Its reluctance changes abruptly above a certain magnetic flux density. At this point, the magnetic device is defined as being in saturation.

The design of the ferroresonant transformer allows one magnetic path to be in saturation, while the other is not. As a result, further change in the primary voltage will not translate into changes in the saturated, or secondary voltage, and voltage regulation results.

Generators come in many shapes, sizes and styles. A Generator is essentially a self contained piece of machinery which is capable of producing power in either single phase (Same as what you use in your home - 240 Volts) or three phase (Generally reserved for the powering of industrial equipment and applications - 415 Volts). Above is a basic layout of a larger scale Diesel powered Generator (Three phase), which could be found in an indutrial application or as a standby source of power for a large building in case of blackout.
