ELECTRODYNAMIC LINE CONDITIONERS. Power Stabilizer
STEROGUARD THREE-PHASE +N 230-400V.

GENERAL FEATURES
TRANSIENT VOLTAGE SUPPRESSOR
The protection against transient overvoltages generated by atmospheric discharges or by switching process is carried out by type 2 (cat. C) surge arresters complying with EN 61643-11/VDE 0675, part 6-11 characterized by a nominal discharge current (8/20) ln of 40 (or 60) kA, by a discharge current with Imax impulse of 50 (or 110) kA, a up protection level not greater than 1300 V and a response time tA shorter than 25 ns.
ISOLATION TRANSFORMER
This component, thanks to the electrostatic shield inserted between primary and secondary windings, ensures the galvanic separation and high attenuation of common mode noises. It is characterized by N delta-star configuration or F or N thermal class, low output impedance and insensitivity to the power factor. The insulation between primary and secondary, primary and shield, secondary and shield is greater than 3000 V during one minute.
ELECTRODYNAMIC VOLTAGE REGULATOR
It ensures the “true RMS” value of the voltage with ±1% output accuracy even in the presence of strong harmonic distortions.
The innovative control circuit, combined with the structural reliability of the electrodynamic stabilization system, has the following characteristics:

Response time from 6 to 40ms/Volt, depending on the model

Overload capacity 10 times the nominal voltage for 10 milliseconds, 5 times for 6 seconds, twice for 60 seconds

Efficiency of 97-98%

Insensitivity to load power factor and load variations

Insensitivity to mains frequency variations, in ±5% range

Harmonic distortion introduced lower than 0.2% under any operating condition (virtually zero)

Internal impedance that varies, according to the models, from 0.52 to 0.0015 Ohm (it does not require a new sizing of the protections being irrelevant compared to the line impedance)

Sizing of the magnetic components aimed at limiting iron and copper losses in order to create a cooling system that only uses the natural convection. In fact, the use of fans requires maintenance, filter cleaning and replacement on average every two years.
