- Built-In Reliability, Ten-Year Warranty
Reduce maintenance and repair costs with the industry’s only voltage regulator control with a worldwide, ten-year, no-questions-asked warranty.
- Ethernet Communications
Quickly integrate the SEL-2431 into Ethernet or serial communications networks with DNP3, SEL, and synchrophasor protocols. The SEL-2431 comes standard with a copper or fiber serial communications card of your choice in Port 1. Populate Port 2 with another serial communications card or with a dual Ethernet communications card. Ethernet port options include copper and/or fiber.
- USB Flash Drive Interface
Retrieve event reports, load profile information, tap history, and other system parameters with a USB flash drive. Stay connected to your system without a network for troubleshooting analysis and planning. The USB feature includes a secure authentication key, which is required for front-panel Level 2 access, reducing the risk of access by unauthorized personnel.
- IEEE C37.118 Synchrophasors
Easily monitor your network with built-in IEEE C37.118 synchrophasors.
- 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 the large front-panel display and programmable operator control interface pushbuttons for easy control.
- 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.
