  • Total protection against surges, gaps, interruptions and voltage drops in public supply networks of 230V and in autonomous electric generators.
  • When a disturbance is detected Overcontrol protects the connected equipment cutting to him the electrical supply. After a minimum warning time of 2 seconds or when the danger ceases Overcontrol reconnects the equipment.
  • Protection voltage levels are adjustable by user by two regulators, one for highs and another for lows. Adjustable levels are for long duration disturbances (more than 0.02 seconds) bellows 300V. For more than 300V disturbances the protection is compulsory and immediate.
  • Users can choice the best compromise between safety and comfort as conditions vary. Selectable low cut level is from 140 to 240. Selectable high cut level is 240 to 300.
  • Use position mark as a switch and pre-set optimum control marks for protection of arc welding equipment with inverter power source (W positions).
  • The two poles (phase and neutral) are disconnected instead of a single pole to ensure true and safe disconnection of the equipment.
  • Cutting of supply without mechanical contact (without relays) of maximum speed and safety. No slow contacts, no sparks and no wear.
  • Generous dimensioning of components. Powerful: circuit capable of controlling 40 amps RMS (9KVA) on PCB.
  • Intelligent control by microprocessor and display of high luminosity indicator of alarms and of real tension at the entrance (useful to analyze falls by consumption and browouts).
