Power Supply Unit Ernitec ELECTRA-PWR-240-48 240W 48V

The Ernitec ELECTRA-PWR-240-48 is a compact DIN-rail power supply that delivers 48 V DC at 240 W from a universal 100–240 V AC input. Designed for industrial environments, this unit mounts on TS-35/7.5 or 15 DIN rails and provides a stable power source for Ethernet devices, surveillance systems and other equipment that require consistent DC voltage in harsh operating conditions.

Advantages

The unit offers a small footprint and convenient DIN-rail installation while maintaining stable performance. It includes built-in protections against short circuit, overload, overvoltage and overtemperature, and relies on free-air convection cooling to limit temperature rise. The wide operating temperature range allows placement in demanding industrial settings.

Suitable for

• Powering industrial Ethernet switches and network equipment
• Supplying DC power to surveillance cameras and recording systems
• Feeding control cabinets and automation modules
• Use in machinery and other equipment requiring 48 V DC at up to 240 W

How to use

Install the ELECTRA-PWR-240-48 on a compatible TS-35 DIN rail and connect the AC input to a suitable 100–240 V AC supply. Connect the 48 V DC output to the target device(s) observing correct polarity. Ensure protective wiring and grounding follow local electrical codes. Allow adequate ventilation around the unit to enable convection cooling and avoid enclosing it in a fully sealed cabinet without ventilation.

Recommendations

Place the unit in a dry, dust-reduced location with sufficient airflow. Verify load does not exceed 240 W and periodically inspect terminals and mounting for secure connections. Use surge protection at the AC input in installations exposed to unstable mains voltage.
