2. Visual and structural features
1. A long-shaped ultra-thin gray metal case, with mounting holes on both sides for wall hanging, suitable for embedded/wall-hanging wiring installation
<t_XXXXXXXXX> <t_XXXXXXXXX>
2. The red terminal on the left is the mains power input (L live wire, N neutral wire, and grounding indicator is clearly marked), while the blue terminal on the right is the 12V DC output terminal; the zones are clearly defined, making it easy to avoid incorrect connections.
<t_XXXXXXXXX> <t_XXXXXXXXX>
3. Longitudinal heat dissipation holes on both sides of the casing provide good passive heat dissipation, suitable for long-term continuous operation
<t_XXXXXXXXX> <t_XXXXXXXXX>
4. Terminal zoning design, organized multi-channel output wiring, making construction more convenient
III. Performance Advantages
1. Wide-range mains input: It can operate smoothly even under voltage fluctuations of 180–265V, suitable for commercial power supply scenarios.
<t_XXXXXXXXX> <t_XXXXXXXXX>
2. 400W high-power constant voltage output, capable of powering multiple sets of 12V LED light strips, light boxes, and illuminated signs.
<t_XXXXXXXXX> <t_XXXXXXXXX>
3. Multiple safety protections: Complies with SELV safety ultra-low voltage design, includes built-in overload, short circuit, and over-temperature protection, suitable for long-term use in lighting projects.
<t_XXXXXXXXX> <t_XXXXXXXXX>
4. Full compliance certifications ensure smoother acceptance for foreign trade shipments and commercial indoor projects.
4. Applicable Scenarios (Real-World Application Direction)
- Commercial lighting: illuminated characters on store doors, advertising light boxes, and linear light strips in showrooms are powered centrally
<t_XXXXXXXXX> <t_XXXXXXXXX>
- No master light in home decoration: Whole-house 12V low-voltage COB/2835 LED strip bulk power supply
<t_XXXXXXXXX> <t_XXXXXXXXX>
- Small commercial low-voltage systems: display case lighting, shelf light strips, indoor landscape lighting projects
5. Usage Precautions
1. It is recommended to keep the long-term load below 80% of the rated power (≤320W) to extend the lifespan of the power supply.
<t_XXXXXXXXX> <t_XXXXXXXXX>
2. Ensure the heat dissipation holes remain open for ventilation; do not seal or wrap them during installation.
<t_XXXXXXXXX> <t_XXXXXXXXX>
3. The wiring must clearly distinguish the left side for AC input and the right side for DC output; reverse or incorrect connection is strictly prohibited.
