Feature: 1. Using aluminum alloy heat sink shell, good heat dissipation performance, and corrosion resistance. 2. Using filter capacitors, with high frequency and high ripple, can improve high‑efficiency and smooth DC output. 3. The filter inductor has high magnetic flux density, and the one‑piece design has good stability. 4. Adopting SMT process, resistance and capacitance MOS tubes are all SMD originals, with high integration, high reliability and high stability. 5. 9-40V to 24V buck-boost power supply is suitable for motors, car navigation systems, recorders, photovoltaic panels, LED strips, bulbs, fans, cameras, etc. Specification: Item Type: Voltage Regulator Product Model: TBC094024C72C Product Material: Die-cast aluminum Input Voltage Range: 9-40V Output Voltage: 24V Output Current: 3A Output Power: 72W Shell Size: Approx. 74 x 74 x 32mm / 2.9 x 2.9 x 1.3in Working Temperature: -40-80℃ Waterproof Rating: IP68 Application: Motors, car navigation systems, recorders, photovoltaic panels, LED strips, bulbs, fans, cameras. Package List: 1 x Voltage Regulator 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.
