Virtalähde Ernitec ELECTRA-PWR-75-48 75W 48V

The Ernitec ELECTRA-PWR-75-48 is a compact industrial DIN-rail power supply that delivers 48V DC at 75W. It accepts a universal 100–240V AC input and is designed for installation on TS-35 DIN rails (7.5 or 15 mm). Built for harsh industrial environments, the unit provides a practical and convenient DC power source for Ethernet devices and other industrial equipment where a stable 48V supply is required.

Advantages

The unit combines a small footprint with practical features for industrial use: universal AC input, 48V DC single output, and a 75W power rating. It includes built-in protections against short circuit, overload, overvoltage and overtemperature to ensure reliable operation. Free-air convection cooling eliminates the need for fans and helps maintain stable temperatures across a wide operating range.

Suitable for

• Powering industrial Ethernet devices and switches
• Supplying DC power to control cabinets and automation equipment
• Small to medium industrial installations requiring a 48V, 75W supply
