2431
Price: $1,334.79
Single-phase voltage regulator control with forward/reverse operating modes.
SEL-2431
Voltage Regulator Control
The SEL-2431 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, or order the SEL-2431 in a preconfigured enclosure for simplified installation. Quickly integrate the SEL-2431 into Ethernet or serial communications networks using fiber or copper options. Retrofit Replacement Kits

Optimize System Voltage
Control system voltage with directional voltage profiles and detailed tap change event reports.
Install Into Multiple Power System Types
Configure operating modes to fit your application: locked-forward, locked-reverse, idle-reverse, bidirectional, cogeneration, or FlexDG.
Apply in Systems With Multiple Sources Including Distributed Generation
FlexDG mode detects whether reverse power flow is coming from cogeneration/DERs or the traditional power source. It can use the change in voltage following a tap and the direction of current in deciding which side to regulate. Bias mode can be applied with FlexDG, cogeneration, and bidirectional modes to improve voltage regulation in low-current conditions.
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 communications interfaces.
Install Easily With a Purpose-Built Enclosure and 19-Pin Interface
The SEL-2431 outdoor enclosure can be mounted to a single-phase voltage regulator, pole-mounted for midline installations, or remotely mounted in distribution substations. With preconfigured options for precise-timing devices and radio-ready communications equipment, the SEL-2431 enclosure offers a modernization path for advanced distribution management systems (ADMSs) and system-level volt/VAR optimization. The optional 19-pin universal interface supports multiple voltage regulator models with a single interface.
