Τροφοδοτικό ERNITEC ELECTRA-PWR-120-24, Μοντέλο ELECTRA-PWR-120-24

ERNITEC ELECTRA-PWR-120-24 is a compact DIN-rail power supply that provides a regulated 24 V DC output for industrial and surveillance network equipment. The unit accepts universal 100–240 V AC input or a DC input, is designed for installation on TS-35/7.5 or 15 DIN rails, and is built to operate in harsh environments with a wide operating temperature range and multiple protection functions.

Advantages

The power supply is compact and suited for confined control cabinets. It features universal AC input with a selectable input range, free-air convection cooling for fanless operation, and protection against short circuit, overload, over-voltage and over-temperature. The device includes an LED power indicator, has passed 100% full-load burn-in testing and carries UL 508 approval and industrial immunity compliance.

Suitable for

• Powering surveillance cameras and network video equipment
• Supplying 24 V access control devices and sensors
• Industrial Ethernet and control equipment requiring DIN-rail mounting

How to use

Install the unit on a TS-35/7.5 or 15 DIN rail inside an appropriate enclosure. Connect the AC mains (100–240 V) or compatible DC source to the input terminals, set the AC input range switch if required, and connect the 24 V DC output to the load, observing correct polarity. Ensure adequate ventilation around the unit for convection cooling. Verify LED indication and check the output with a multimeter before connecting sensitive devices.

Recommendations

Use the power supply in indoor industrial enclosures or cabinets with restricted dust and moisture exposure. Position so airflow is not obstructed, avoid close proximity to heat sources, and observe the specified temperature range. Respect wiring best practices and grounding; use short, appropriately rated cables and add external surge protection where required by the installation environment.
