How to use
Mount the unit in a well-ventilated location according to the installation requirements and ensure adequate spacing from heat-sensitive components. Connect the AC input to a suitable mains supply using appropriate wiring and protective devices, and connect the 12 V DC output to the load with correctly sized cables to minimise voltage drop. Verify polarity and secure all connections before applying power. Observe the rated output current and avoid exceeding the maximum specified load to ensure reliable operation.
Usage recommendations
For reliable performance, install the power supply in a ventilated enclosure, use fuses or circuit breakers on the input and output where applicable, and route DC output cables to minimise voltage drop. When powering long LED runs or multiple devices, calculate cable gauge and distribution to keep voltage within acceptable tolerance for the load.
