Universal Voltage Relay Type SW32V

Universal-Voltage-Relay for monitoring of over- and undervoltage in DC-, AC- and 3-phase-voltages incl. monitoring of phasesymmetry and phase-sequence

Universal Voltage Relay Type SW32V

Part number


Product description

 

The SW32V voltage relay is a high-quality voltage monitor with a large measurement range for monitoring direct, alternating and three-phase networks for overvoltage and/or undervoltage. In three-phase current networks, phase symmetry and phase sequence can be monitored in addition.

The limits are set in volts. That allows using the unit with various rated voltages.The digital display is used to display the measurements and to precisely set limits, response times and functions.

Summary of the functions
For use as a voltage monitor in energy generation and distribution plants, especially in-plant systems such as PV plants or combined heat and power plants. Voltage monitoring in machines and plants to prevent errors, damage or failures in sensitive equipment or devices.

  • Voltage monitoring in direct current networks DC 10.0…600 V
  • Voltage monitoring in alternating current networks AC 15.0…480 V
  • Voltage monitoring in three-phase current networks with//without N up to 3AC 830 V
  • Preset programs for grid- and plant protection according to bdew directive (medium voltage)
  • Asymmetrical and phase sequence monitoring connectable
  • Real root mean square measurement (for AC, both half waves)
  • 2 Alarms/output relays, 1 each change-over contact
  • Alarm and reset delay for every limit value can be individually set
  • Setting of limits and hysteresis in volts
  • Measurement value simulation to check the settings
  • Code lock can be enabled
  • Control voltage AC/DC 24-270 V
  • Distributor housing for panel mounting, 4 TE (70 mm), front-to-back size 55 mm
  • Mounting on 35 mm mounting rails DIN EN 60715
