Series STFA
Three-phase automatic voltage stabiliser
Series STFA
Three-phase automatic voltage stabiliser
Three-phase voltage stabiliser for fast and automatic correction of the output voltage in the event of mains voltage variations and consumption variations in the load.
Mains conditioner with galvanic isolation transformer and electrostatic screen, providing a perfectly stable output voltage, as well as attenuation and filtering of mains disturbances.
Features
- Galvanic isolation and continuous regulation by series booster between input/output and motorised variable autotransformer.
- High resolution digital controller.
- Display for output voltage visualisation.
- Magneto-thermal ON/OFF switch on the front panel.
- Terminal connection inside to protect against dangerous direct contacts.
