How to use
Mount the unit on a standard DIN rail inside a control cabinet or distribution enclosure. Connect the AC mains input according to local wiring regulations and the unit's input terminal markings, and connect the 12 V DC output to the load terminals, observing correct polarity. Ensure adequate ventilation and avoid mounting directly next to heat-producing components. Verify output voltage under load after installation and confirm that the connected devices do not exceed the 2 A output rating.
Usage recommendations
Place the power supply in a location with stable ambient temperature and good airflow, keep wiring runs short and properly sized to minimise voltage drop, and use appropriate fusing on the input or output circuits where required by local standards. For continuous or critical applications, maintain a margin below the maximum rated current to improve longevity and reliability.
