INFORMATION

Description

The computer max-f series of regulators is within the fast regulator range, with a response time from 40 ms, adapted to real time compensation requirements.

Main Features:

  • Shows by display: cos φ, voltage, current, THD(I) and, besides, records in memory maximum values for voltage and current.
  • Provides the “phase selection” function, that allows the user choosing the power line phase where the measuring current transformer (CT) has been placed in allows viewing in display the variation of cos φ, line current and THD(I), when manually connecting or disconnecting capacitor steps.
  • Indication by display or through output of following alarm conditions: Compensation failure, Over-compensation, Over-voltage, Over-current, C.T. not connected or open, Line current below measurable value.

Applications

The computer Max-f system has been designed to compensate installations that have a special load typology and require real time compensation, such as welding units, cranes, lifts and lifting equipment, smelters, hospitals, automotive industry or any other sector/unit that requires a real time compensation.
