• Automatic Polarity adjustment of Phase rotation.

• Separate alarm relay with potential free terminal.

• Following Alarms can be selected (enable/disable and status) low power factor, hunting, abnormal Cos, undervoltage, overcapactive, wrong frequency, overcurrent, overvoltage, overtemperature (for fan and system) and voltage harmonic distortion (THD).

• All steps are released at voltage dropout.

• Number of steps setting and display 1 ... 12.

• Manual stepping setting and display.

• Fixed stepping setting and display.

• Plug in connection at rear side.

• State of art microprocessor technology.

• Suitable for LV and HV networks.

• Allows Self-Configuration.

Performance:

• intelligent stepping algorithm for optimum step utilization and fast response

• all traditional stepping sequences also available

Simplified Installation And Set-Up:

• quick and simple mounting and wiring

• insensitive to current transformer polarity and phase rotation polarity

• a special menu allows controller self-configuration

Monitoring And Protection:

Alarms:

• should a disturbance occur on the network or in the capacitor bank, alarms are indicated on the screen and alarm contact closure is initiated

• The alarm message is maintained on the screen once

• The fault clears and until it is manually reset

• Last five alarms are stored in alarm log
