- Built-In Reliability, No-Hassle Warranty
Reduce maintenance and repair costs with the industry's only voltage regulator control with a worldwide, ten-year, no-hassle warranty.
- Plug-In Voltage Regulator Compatibility
Use simple hinge and wiring kits to mount the SEL-2431 Voltage Regulator Control directly into existing control cabinets for Cooper/McGraw-Edison, GE, Howard, and Siemens/Allis Chalmers 32-step, single-phase voltage regulators.
- Easy Application Settings
Quickly commission new controls with a minimal number of simple, application-specific settings.
- Rugged Design
Rely on the industry's widest ambient temperature operating range, –40° to +85°C (–40° to +185°F).
- Large Display and Operator Controls
Use large front-panel display and programmable operator control interface pushbuttons for easy control.
- Supports the following modes of operation:
- Locked forward
- Locked reverse
- Idle reverse
- Bidirectional
- Cogeneration
- Personalize LCD messages using event-driven display point settings.
- Create an integrated control system with a variety of I/O and communications options.
- Analyze system performance using built-in Sequential Events Recorder (SER) and waveform event reports.
- Use ACSELERATOR® QuickSet™ SEL-5030 or SEL-5010 Relay Assistant Software to manage your voltage regulator control settings.

- Source-side measured voltage input. Note: With the standard load-side voltage input, the SEL-2431 can calculate source-side voltage and operate in reverse and bidirectional modes.
- Additional inputs and outputs: 4 programmable self-whetted (12 Vdc) contact inputs and 3 programmable contact outputs
- Raise/lower toggle switch
- Two communications port options, including any combination of:
- EIA-232
- EIA-485
- Fiber-optic, 200µm, multimode, V-pin connector
- Fiber-optic, 62.5µm, multimode, ST® connector
With optional communications ports, choose from SEL ASCII, SEL Compressed ASCII, Fast Meter and Fast Operate, and DNP3 Level 2 Slave protocols.
- Conformally coated circuit board
- Retrofit replacement kits.
Replace existing voltage regulator controls with the SEL-2431 direct replacement mounting and wiring kits. These kits provide all the parts needed to easily replace existing controls with the SEL-2431.
