About This 48V Step Down to DC 12V 20A Waterproof Level Upgrade：With an IP68 waterproof rating, it can remain dry inside even after being submerged 1.5 meters underwater for 24 hours. Its moisture-proof function can control the humidity below 80%, and it can also withstand the impact of a free fall from a height of 1 meter, comprehensively protecting the stability of the internal core. Enhanced Safety Assurance: Equipped with a built-in smart chip, it monitors the input voltage every 0.1 seconds, accurately identifying overvoltage and undervoltage. In case of overcurrent, overload, overheating, short circuit, etc., it can quickly respond within 0.05 seconds to ensure the safety of power usage. Improved Heat Dissipation: The upgraded fin-type heat sink has increased the heat dissipation area by 50%. With a thick aluminum plate inside that has a thermal conductivity of 237W/(m·K), it can reduce the operating temperature by 20℃, extending the service life and ensuring stable power supply. Greater Durability: The die-cast aluminum shell is manufactured through five precise processes. It can withstand an external force of 500N, and the interface has a plugging and unplugging lifespan of over 10,000 times, with a stable structure. Higher Efficiency: By relying on synchronous rectification technology, it achieves a 96% conversion efficiency. It can precisely regulate the current and voltage with low energy consumption. With the built-in intelligent protection, whether for light-load devices of 10 - 20W or heavy-load equipment of 100 - 200W, it can stably supply 12V DC power.
