Eaton Sola 210 210-26-725-00 Manuel D’Utilisation

Eaton's Sola ferroresonant products are proven 

technology. In 1938, Sola was 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, Eaton's Sola ferroresonant power conditioners 

supply sinewave output, which is  especially important 

for computer applications. 

Whether you purchase a model 200, 210 or 26 voltage 

regulator, you can count on an average of 25 years 

service from your unit. 

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 

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.

•  Superior Low Line Performance

   Specified performance is maintained for all loads    

0 - 100% of nominal rating.

•  Switchmode Computer Load Compatibility

   Able to support typical computer loads when input 

supply mains voltage is 50% below nominal.

•  240 Volt, 230 Volt or 220 Volt Models

    Separate models to suit different nominal supplies or 

particular nominal output voltage requirements.

•  200% Overload Rated

   Suitable for use with computer start up overloads. 

Units are output short circuit proof.

•  On Site Configuration

   7.5 to 18kVA units can be site configured as Single 

Phase or Three Phase operation, if required.

•  Selectable Voltages

   Hardwired 26 Series units have selectable input and 

output voltages.

•  5 Year Warranty

   Exceptional MTBF (Mean Time Between Failure), 

an optimum combination of performance to cost 

effective power conditioning.
