- 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.
- 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
