[24VDC to 12VDC Converter] This buck converter 24V to 12V converts the DC 24V into DC 12V. Low power consumption. Voltage input: DC 15-40V, output: DC 12V. Max Current: 15A 180W. WARNING: 1.Please test whether the output voltage is correct before use; 2.Please confirm the positive and negative polarity of the power before wiring; 3.Must hook the negative wire to GND before use, or the output volts will not change! [With Fuse More Safer] For the safety of devices, our 18v to 12v converter are equipped with fuses. When the voltage is too high, the circuit breaks down or is abnormal, the fuse will blow and the transformer will stop working, thereby protecting the electrical appliances. In addition, this can reduce the risk of fire or explosion. High conversion rate over 96%, output correctly. High quality and performance more durable, longer service life. [IP67 Waterproof] This converter 24V to 12V adopted heat conduction organic silica gel filling and sealing technology, waterproof,
