Feature: 1. Having an aluminum alloy heat sink shell, which is one‑piece molding, with better heat dissipation 2. The voltage converter is completely sealed with silicone potting and resin potting, so having better thermal conductivity 3. With high frequency and high ripple, special filter capacitor, giving you a good experience 4. Using SMT process, the resistance and capacitance M0S tubes are all SMD originals, you can use the voltage converter with confidence 5. With high integration, high reliability and high stability, the voltage converter can well meet your needs Specification: Item Type: 24V to 12V Converter Product Material: Die-cast Aluminum Product Model: THJ2412U480Z Input Voltage: 24V Output Voltage: 12V Output Current: 40A Output Power: 480W Product Shell Size: Approx. 100 x 80 x 38mm / 3.9 x 3.1 x 1.5in Waterproof Rating:IP68 Working Temperature: -40-85℃ Uses: Motors, Car Navigation Systems, Recorders, Photovoltaic Panels, LED Strips, Bulbs, Fans, Cameras. Package List: 1 x 24V to 12V Converter Note: 1. Please correct wiring and installation, and confirm that the positive and negative polarities of the input and output are correct before powering on to work.2. The battery power at the input end is within the input voltage range and the power is sufficient to ensure the normal operation of the power converter.3. Please install it in a well‑ventilated environment to avoid over‑temperature protection of the power converter due to heat accumulation.
