The SEL-9322 15 Vdc Power Supply is an ac-to-dc or dc-to-dc converter designed for harsh physical and electrical environments, including those found in electric utility substations. The SEL-9322 provides a nominal 15 Vdc at up to 1 A to power communications or instrumentation devices. The low-voltage output can be derived from higher-voltage dc battery sources or from higher-voltage ac sources. The range of options covers electric, gas, and water utility; telecommunications; industrial plant; and remote telemetry battery-backup applications.
SEL Radio Power Supply—Power the SEL-3031 Serial Radio Transceiver and the SEL-3060 Ethernet Radio to support electric utility distribution automation, distributed generation, SCADA, and faster protection applications.
SEL-3505 Power Supply—Power SEL-3505 Real-Time Automation Controllers (RTACs) to support remote-site automation.
SEL-3622 Power Supply—Power the SEL-3622 Security Gateway to secure equipment at remote sites.
Industrial Equipment Power Supply—Provide power to equipment in unconditioned industrial locations. The SEL-9322 performs in harsh environments and meets SEL’s strict quality standards.
The Firmware IDs for older versions of the firmware can typically be found in Appendix A of the instruction manual.
