Description of High-Power Buck Converter Step-Down Module - XINGYHENG 20A 300W, DC 6-40V to DC 1.2-36V, Adjustable Constant Voltage Current Power Module with Short Circuit Protection for Charging, LED Drive

Super material: It is made of electronic accessories, nickel plating on surface(anti-oxidatioan), inner conductor: pure copper.it is long lasting and durable for you to use. Package including: 1 Pack of Constant Current Voltage Step-up Module. Moreove. The buck module has 2 heat sinks that could enhance heat dissipation. When there is a big difference between input and output voltage, please decrease power and current. With LED indicator, more stable and reliable to use. Input and output: With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust output voltage and current. Output Current: 20A(max.), 15A (suggested). Efficiency: 97% (24V to 12V, 20A). Output Ripple: Less than equal 50mV. Designed with 75V/80A large current dual MOS tube. High Power High Efficiency: 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. A wide range of applications: Widely uses in power transformer, DIY adjustable power supply, LED car display, mobile power, industrial equipment appliances, LED driver, monitor, solar energy, fan, battery conversions, micro-controllers, and electronic projects. so on. Maintain stable output voltage and limit the output current over a range of input voltages.

You may have to fix it yourself.

The first one didn't work! Replaced after 2 weeks, the radiator bracket is crooked, the amplifier control potentiometer was damaged. The input plug is crooked, I no longer want to return it, I can't wait and I don't have time to go back and forth to return the goods.

Pros
  • Amazing
Cons
  • Very expensive

A pretty good device, the resolution setting is a bit weak.

So far I'm happy with it, I've used it to charge single LifePO4 cells. The only complaint I have is that the output voltage adjustment is not smooth. You have to turn this screw several times to get the exact tension you want. Besides, he does his job quite well.

Pros
  • Free for educational purposes
Cons
  • Negative impression

Voltage cannot be adjusted.

I also had heatsinks installed incorrectly and when I got down to testing and adjusting I couldn't get it to adjust from 16 volts with no load. During this test I applied 20.3 volts. This IC blew out on a pin that appears to be connected to a voltage potentiometer, but continues to provide 16 volts with no load.

Pros
  • Absolutely amazing!
Cons
  • ill thought out

Buen convertidor DC - DC

You should use this DC to DC converter and use it for comparison, in case of failure If you see the photo, the battery is 16V DC and the converter consists of 12.19V DC.

Pros
  • Stylish and modern design
Cons
  • Some cons

This works great but not for mobile scooters lol!

I am not a professional e-bike. I got this because I have a surplus of power tool batteries and a couple of portable scooters that need batteries so I use power tool batteries and a step down transformer to step down 40v to 24v and it works great but doesn't do well with reverse voltages rightly releasing the throttle on mobile scooters. . I don't know if e-bikes use permanent magnet motors, but mobile scooters do and I think that could be an issue. I will try to use this transformer for my 40V

Pros
  • Very good price
Cons
  • Secret

He does what he says for a good price.

I'm using this to step down the 32 VDC from the solar panel to the 30 VDC Jackery 500 maximum. There are no instructions, so make sure you do some googling to understand what you're doing before you begin. Overall it does what I need and it's cheap, but it might not be the best solution for a variable voltage input like a solar panel. I only need it to dissipate about 75 watts, which it usually does well, but sometimes it fails and I have to turn it on and off to get power. Maybe the problem is

Pros
  • Hands Free Operation
Cons
  • Ok
