The SEL-2431 Voltage Regulator Control is compatible with most 32-step, single-phase voltage regulators manufactured in North America. Use various hinge and wiring kits to easily upgrade existing controls without removing the regulator from service. Quickly integrate the SEL-2431 into Ethernet or serial communications networks using fiber or copper options.

Applications

Optimize System Voltage—Control system voltage with directional voltage profiles and detailed tap change event reports.

Install Into Multiple Power System Types—Apply locked-forward, locked-reverse, idle-reverse, bidirectional, or cogeneration operating modes.

Track Tap Position Accurately—Monitor motor current and holding switch status for accurate tap position tracking.

Monitor Motor Current—Monitor and troubleshoot your voltage regulator with recorded tap change motor current waveforms.

Integrate Into Distribution Automation Networks—Integrate the SEL-2431 into Ethernet or serial communications networks with DNP3, SEL, and synchrophasor protocols. Both the serial and the Ethernet ports are available with copper and fiber-optic connection options.

Reduce Commissioning Time—Accelerate installation and commissioning with application-specific settings. Regulate voltage, apply advanced metering, and implement event recording capabilities with fewer than 20 settings.

Quickly Retrieve Data—Event reports, tap change history, load profile data, and Sequential Events Recorder (SER) data are all available through the USB port or other communications interfaces. You may also use the USB port to quickly transfer settings, upgrade firmware, and expand onboard storage capacity.
