These have been designed to provide the highest level of protection to electrical appliances connected to distribution lines disturbed by sudden voltage variations, HF noises and spikes. Statistically, these phenomena represent more than 95% of electric anomalies that could be the cause of breakdowns and poor operation of any kind of appliance connected to distribution lines.
The standard models embody four different devices, each one devoted to the compensation or attenuation of a specific electrical fault:
– a suppressor of voltage spikes,
– a line filter,
– a high attenuation isolating transformer,
– a voltage regulator.
The range is made up of models with powers that vary from 0.5 to 830 kVA and use two different voltage regulation technologies:
a) Static switching technology for loads with single-phase absorption (up to 8 kVA) and three phase (up to 24 kVA), these are MINISTATIC models.
b) Electrodynamic regulation technology via series transformer and variable autotransformer for loads with three-phase absorption (up to 830 kVA): these are STEROGUARD models.
The two regulation technologies and the wide range allow the most suitable regulation system to be supplied to meet the specific needs of the various kinds of appliances.
MINISTATIC electronic line conditioners
They have specific performances to power electronic appliances with medium to low powers that require a particularly high stabilisation speed such as: process and numerical controls, robotics, medical equipment, telecommunications and computers.
The range is made up of standard models with powers ranging from 0.5 to 24 kVA. Furthermore, because the manufacturing criteria make these conditioners highly versatile, on request, versions can be designed with customised specifications for the most varied applications.
The range is made up of single-phase models with powers ranging from 500 VA to 8 kVA. The noiseless operation, the compact size and fitness for use make them ideal for installation in offices and laboratories as well as in professional applications like automotive, chemical, food and telecommunications industry.
This range is made up of three-phase models with powers from 6 to 24 kVA. It is particularly suitable for powering NC machine-tool equipment, automation plants and telecommunications systems.
These models are fitted with delta-star isolating transformer and create a “real neutral” and subsequently make it possible to have a single-phase 230 V voltage using a three-phase 400 V plant without neutral.
STEROGUARD electrodynamic line conditioners
They provide a maximum level of protection to high power appliances, with high electromagnetic susceptibility, connected to distribution lines disturbed by sudden voltage variations, high frequency interferences and voltage spikes.
The regulation system is made up exclusively of magnetic components capable of supporting loads with high inrush currents. The use of electronic components is limited to the control of the mains and of magnetic components stabilising the voltage. Thanks to these features, the electromechanical line conditioners stand apart for their high electromagnetic immunity and for the absolute reliability. They are, therefore, particularly suitable for powering radio-TV transmitters, telephone systems, radar systems, motors, compressors, pumps, medical equipment, machine tools and so on.
Thanks to their constructive features, maintenance can be carried out even by technical staff with only a basic knowledge of electrical installations.
