Currently, we have many devices used for advertising, lighting, business or installing security cameras in front of doors, outdoors, places that are affected by weather, sun and rain, and these devices need a DC 5V, 12V or 24V DC power source, so we must equip it with a power source that can withstand outdoor wind and rain so that our device operates stably and for a long time. SPECIFICATIONS: Input voltage: 220V AC Output voltage: 12V DC Rated current: 33A (400W) Protection: Short circuit / Overload / Overvoltage / Overheat Cooled by integrated DC electric cooling fan Durable quality, high reliability Waterproof standard reaches IP 43, can be used outdoors, rainproof. The output voltage does not decrease and is stable, safe for the circuit. The housing is made from high-quality aluminum and has a standard thickness to help dissipate heat quickly, creating stable power source operation. Unique design, makes installation, installation, maintenance and repair easy.12V 33A outdoor honeycomb power supply is commonly used to power advertising signs, braille letters, LED strip lights, LED neon signs, molded LEDs, modular LEDs, bar LEDs, and luxeon LEDs. outdoor camera.
