✅Key Selling Points
1. Wide-range mains power adaptation for 180–240V, stable operation under grid voltage fluctuations, widely used both domestically and internationally
<t_XXXXXXXXX> <t_XXXXXXXXX>
2. It provides a constant voltage output of 12V with 25A and 300W power; it can be used in bulk for 12V LED strip lights, linear lights, and advertising modules
<t_XXXXXXXXX> <t_XXXXXXXXX>
3. Ultra-thin long body design, suitable for installation in concealed narrow spaces such as ceiling light slots, cabinet interiors, and display case interlayers
<t_XXXXXXXXX> <t_XXXXXXXXX>
4. Large-area honeycomb heat dissipation holes at the top and bottom + built-in inductor airflow design, ensuring high heat dissipation efficiency and low temperature rise during prolonged full-load operation
<t_XXXXXXXXX> <t_XXXXXXXXX>
5. SELV low-voltage safety level, combined with multiple circuit protections; automatically safeguards against short circuits and overloads, thereby extending the lifespan of the rear lighting fixtures.
<t_XXXXXXXXX> <t_XXXXXXXXX>
6. The input and output terminals are arranged in separate zones, with clear wiring divisions, making the engineering connections easy to distinguish.
⚠️Usage Instructions
1. Clearly distinguish between AC input at the upper end and DC 12V output at the lower end; it is prohibited to connect the AC and DC terminals in reverse order.
<t_XXXXXXXXX> <t_XXXXXXXXX>
2. The system should maintain a 20% power margin for operation; it is not recommended to run at full 300W continuously for long periods.
<t_XXXXXXXXX> <t_XXXXXXXXX>
3. Ensure there are designated ventilation gaps; the housing must not be sealed to prevent heat dissipation.
