The input voltage range of -down converter is DC 6-40V, and the output voltage range is DC 1.2-35V. It can be used to convert 24v 12v 5v, the adjustable output current range is 0-20A, and the maximum output power is 300W. Step-by-step regulators can be used for constant output current. The input voltage range of this step-by-step converter is from 6V to 40V, and the output voltage and current can be adjusted accurately. The efficiency is as high as 95% (measured at 20A, converted 24V to 12V). It uses 75V/80A high current dual MOS tube design. The input and output adopt high-frequency low-resistance electrolytic capacitors, low ripple, and provide stable output. Use these high-current 30A screw terminals to facilitate wiring. -down module has 2 heat sinks to enhance heat dissipation. When there is a between the input and output voltage, please reduce the power and current. Application: motor, audio, display, LED car display, air conditioner, fan, solar energy, photovoltaic energy, DVD, LED light, pump, industrial equipment, etc. Colour:As shown Material:Metal Package Contents: 1 * 20A high-power synchronous rectifier step-down constant voltage constant current power supply module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
