60V 7A Adjustable Step Down Voltage Regulator, A Handy Tool To Have!

Sometimes when testing FPV stuff, they all require different input voltages and it can be annoying when you don’t have the right battery for the job. That’s when an adjustable voltage regulator comes in handy! I found a cheap one that might be something I’ve been looking for!

What Can You Use It For?

This one is called the “Winners® 7A DC 60V Adjustable Step Down Regulator”.

It takes 8V to 60V and outputs 3V to 32V, with maximum current of 7A.

There is no mention of power rating, but from the spec it says the maximum output voltage and current are 32V and 7A respectively, so that works out to be 224W! But they also warn about overheating and not to go above 5A.

You can use it for converting higher voltage to lower voltage, there are tons applications.

You can use big batteries like 4S or 6S LiPo battery to test your VTX setup even if they only take 12V or even 5V. You can use it to power your FPV goggles, monitor or TX as a last resort if you don’t have any 2S/3S battery. You can even use it as a power supply to your TS100 soldering iron, take a 8S LiPo (or connect two 4S in series), convert it down to 24V and enjoy the full power of your TS100!

Looking For Step Up Regulator?

If you are looking for a step up (boost) voltage regulator, take a look at this one I just reviewed recently. You can convert lower voltage to higher voltage. I personally use it to power my TS100, using a 4S LiPo, and I can get 24V out of it.

A Closer Look at This Voltage Regulator

The screen turns on when the input is connected to a power source between 8V to 60V.

The back-lid screen tells you the output voltage and current, but unfortunately it doesn’t tell you the input voltage! It’s not end of the world, you could still hook up a voltage meter/buzzer. But it would have made this thing so much better if it can read out the input voltage as well! The battery sign under the “winner” logo, is just a part of the logo and doesn’t seem to do anything.

There are two push buttons for adjusting the output voltage, with a increment of 0.05V when under 10V, and 0.1V when it’s over 10V. By holding the button down you can change the voltage a lot faster.

The input and output are screw terminals. They are quite small and only take 18AWG or smaller wires.

Out of the box , the output voltage reading is off by about 0.3V at 12V when I check with a multimeter. But you can calibrate it fairly easily following the instructions on their product page.

What’s in the Box?

The Winner 60V 7A Regulator comes with the main module, screws, red buttons, white nylon standoffs and two transparent plastic sheets for the housing. The assembly is simple and only takes 5 mins.

Here are some close up of the main board. On the bottom there are some pretty beefy heatsink for cooling.

 

This thing comes with nylon standoffs instead of metal standoffs as advertised on their product page. I am a bit disappointed at the false advertising, but that’s not a deal breaker at all.

It’s nothing groundbreaking or amazing, just a cheap and useful tool to have around when testing FPV stuff, or electronics in general :)
