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.
