## Description

20A Power Supply Module DC-DC 6V-40V to 1.2V-35V Step Down Buck Converter Adjustable Buck Adapter CVCC Constant Voltage Constant Current Converter LED Driver

## Features

- Adopting 75V / 80A large current dual MOS tube designed step-down board, Input and output use high frequency low resistance electrolytic capacitor, low ripple, and gives a stable output. Large current 30A connection screw terminals, more convenient to install
- Converter input voltage range is DC 6-40V, adjustable output voltage range is DC 1.2-35V, can be used to convert 24v to 12v 5v, adjustable output current range is 0-20A, max output power is 300W. The step down regulator can apply to constant output current
- With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust output voltage and current. The efficiency can be up to 95%,(measured at 20A, converting 24V to 12V). Short Circuit Protection: Self-recovery(cannot short circuit for long time). Plus, when input and output is common grounded, no-load CV output constant voltage,CC output constant current
- Application: Fit for DIY stabilized voltage supply, LED car display, mobile power, industrial equipment appliances, LED driver, monitor, solar energy, fans, photovoltaic energy, motor, and more
- Package Includes: 1x 20A Power Supply Module

## Questions & Answers

**Q: what material are the fins made of?**
A: Aluminum

**Q: want to increase voltage to recharge dash cam battery (hard wire to vehicle). Battery 12V, 10 Amps, will this work? Low voltage warning.**
A: this should work.

**Q: For the whdts 20a model - what is the adjustable range for the constant current output?  specifically - what is the low value of current !!**
A: They are 6v-40v. If you need to go from 12v lower may I suggest a downstep converter.

**Q: does the 20A buck boost really not come with a on-off switch, thats what the picture and my module look like and how to use the 3 hole on/off deal**
A: No On/Off switch included.
