Power supply unit ERNITEC ELECTRA-PWR-480-24V, model ELECTRA-PWR-480-24V, output 24V

ERNITEC ELECTRA-PWR-480-24V is a compact DIN-rail power supply that provides a stable 24V DC output for professional and industrial equipment. The unit accepts a universal 100–240V AC input and is designed for continuous operation in demanding environments, offering a practical solution for feeding CCTV, network devices and other industrial Ethernet equipment.

Advantages

The power supply combines a compact form factor with DIN-rail TS-35 / 7.5 or 15 compatibility to simplify installation in control cabinets. It includes active power factor correction and multiple protection functions (short circuit, overload, over-voltage and over-temperature) to protect connected devices and ensure stable operation. The unit uses free-air convection cooling and is rated to operate across a wide ambient temperature range.

Suitable for

• CCTV cameras and surveillance systems
• Industrial Ethernet switches and network devices
• Control cabinets and automation equipment
• Any application requiring a reliable 24V DC feed in harsh environments

How to use

Mount the ERNITEC ELECTRA-PWR-480-24V on a TS-35 DIN rail inside an appropriate enclosure or cabinet. Connect the AC mains input (100–240V AC) according to local electrical regulations and wire the 24V DC output to the load, observing correct polarity. Ensure adequate ventilation around the unit for convection cooling and verify protection settings and wiring before powering equipment.

Recommendations

Install the unit in a dry, dust-controlled cabinet and avoid obstructing airflow. Verify that connected loads do not exceed the rated wattage and perform periodic inspections for secure terminals and stable ambient temperature to ensure long-term reliability.
