Power Supply Unit Ernitec ELECTRA-PWR-480-48 480W 48V

The Ernitec ELECTRA-PWR-480-48 is a compact DIN-rail power supply that provides 48V DC at up to 480W from a universal 100–240V AC input. Designed for industrial Ethernet and other equipment in harsh environments, the unit fits TS-35 rails (7.5 or 15 mm) and uses convection cooling to maintain stable operation across a wide ambient temperature range.

Advantages

This compact power supply offers a high 480W output in a space-saving housing suitable for DIN-rail installation. It accepts universal AC input voltage and delivers regulated 48V DC power while including protections against short circuit, overload, over voltage and over temperature. Convection cooling and a wide operating temperature range allow reliable performance in demanding industrial conditions.

Suitable for

• Industrial Ethernet switches and routers
• Automation controllers and PLCs
• Outdoor or factory floor equipment in harsh environments
• DIN-rail power distribution cabinets
