1. The hollow design of the outer shell is more efficient in heat dissipation. The shell can effectively protect the internal components, and the hollow design of the honeycomb hole heats up faster. 2. Multiple protections, stable performance and , multiple protection to safety and stability, and escort your electricity safety 3. High quality, both internal and external, the internal structure is neatly arranged, clear, and the space design is reasonable and standardized, effectively reducing the occurrence of failures 4. 99% of the electronic components used in the circuit are brand-new factory materials and materials. 5. The test is enough, the actual is enough, low interference, sensitive protection mechanism, .The recommended load for long-term work is 80%, or lower Product Description: Protection Type: Automatic Recovery Application range: LED lighting monitoring security exhibition counter industry Work efficiency: 85% Protection level: automatic recovery Cooling type: natural heat dissipation Working environment: -15~55 Display mode: display light Voltage adjustment rate: 0.5 (%) Output ripple noise: 90-100MVP size: 20 x 11 x 5cm Material: Metal colour: white Package Contents: 1 x 12V 20A power adapter Only the above package content, other products are not included.
