Feature 1 The die-cast aluminium heat sink shell is integrally formed for better heat dissipation. 2 Silicone potting has better thermal conductivity, and resin potting is completely sealed. 3 Filter capacitor for high frequency and high ripple, has a special customized electrolytic capacitor. 4 Filter inductance for high magnetic flux density, has a high temperature imported iron silicon aluminium magnetic ring. 5 Through SMT process, the resistance and capacitance M0S tubes are all SMD originals, with high integration, high reliability and stability.Item Type: Voltage ConverterProduct Model: TBC084013R8U276ZProduct Material: Die-Cast AluminiumInput Voltage Range: 8-40VOutput Voltage: 13.8VOutput Current: 20AOutput Power: 276WProduct Shell Size: Approx. 100 x 80 x 38mm / 3.9 x 3.1 x 1.5inWaterproof Rating: IP68Working Temperature: -40-85Application: Motors, car navigation systems, recorders, photovoltaic panels, LED strips, bulbs, fans, cameras. Package List1 x Voltage ConverterNote1. Please wire and install it correctly, and confirm that the positive and negative terminals 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.
