Feature: 1. With aluminum alloy heat sink shell, the converter is integrally formed for better heat dissipation! 2. Silicone potting has better thermal conductivity, and resin potting is completely sealed. 3. High frequency and high ripple is special customized electrolytic capacitor. 4. Filtering inductance that is high magnetic flux density uses high‑temperature imported iron‑silicon‑aluminum magnetic ring. 5. Adopting SMT process, resistance and capacitance MOS tubes are all SMD originals, which has the advantages of high integration, high reliability, and high stability. Specification: Item Type: Voltage Reducer Converter Product Model: THJ4812C240Z Input Voltage Range: 30-60V Output Voltage: 12V Output Current: 20A Output Power: 240W Working Temperature: -40-80℃ Waterproof Rating: IP68 Uses: Motors, car navigation systems, recorders, photovoltaic panels, LED strips, bulbs, fans, cameras. Package List: 1 x Voltage Reducer Converter Note: 1. Please connect and install correctly, and only after confirming that the positive and negative polarity of the input and output are correct, can it be powered on.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.
