[Step Down Voltage Converter] This 24v to 12v step down converter the DC 24V into DC 12V. Low power consumption. Voltage input: DC 15-40V, output: DC 12V. Max Current: 30A 360W. WARNING: 1.Please confirm whether the output voltage is correct before use; 2.Please confirm the positive and negative polarity of the power before wiring; 3.Must connect the input negative wire to GND or - before use, or the output volts will not change! [With Fuse & Safer] For the safety of users, our power adpter converter are equipped with fuses. When the voltage is too high, the current exceeds(35A), 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.
