Power supply unit ERNITEC ELECTRA-PWR-240-24, model ELECTRA-PWR-240-24

ERNITEC ELECTRA-PWR-240-24 is a compact DIN-rail power supply unit that provides a single 24 V DC output for professional electronic and security installations. Designed for industrial and harsh environments, this unit accepts a universal 100–240 V AC input and delivers stable DC power for devices such as CCTV systems, access control panels and other low-voltage equipment. The housing fits TS-35/7.5 or TS-35/15 DIN rails and uses free-air convection for cooling.

Advantages

The unit combines compact size with practical installation on standard DIN rails, enabling space-saving placement in control cabinets. Built-in protections against short circuit, overload, overvoltage and overtemperature ensure reliable operation. Active PFC and compliance with industrial immunity standards provide consistent performance in electrically noisy environments, while UL 508 approval confirms suitability for industrial control applications.

Suitable for

• CCTV camera systems and video equipment
• Access control and door entry systems
• Industrial Ethernet devices and controllers
• Low-voltage security and monitoring equipment

How to use

Mount the power supply on a TS-35 DIN rail (7.5 or 15 mm) inside an appropriate enclosure. Connect the AC input to a 100–240 V AC supply following local electrical codes and ensure correct grounding. Connect the 24 V DC output to the load, observing polarity and current requirements of the connected devices. Leave sufficient clearance around the unit to allow natural convection cooling and avoid obstructing ventilation.

Recommendations

To maintain reliable performance, install the unit in a dry, ventilated cabinet and avoid placing heat-generating components directly above it. Verify that the total load current does not exceed the unit's rated output and use proper overcurrent protection on the output when required by your installation standards.
