DZS Elec Adjustable Electronic Stabilizer Tools & Equipment Review

Glad I checked the voltage before I connected anything. For some horrible reason it accepts 24v to 51v. Definitely a quality control issue or something

I've only used one so far but it works great for dropping the voltage from 20V down to 1.5V to power an LED bulb take care of. The adjustment takes a long time to get there and can be done accurately.

Tested on 02/20/2018 and none of the 10 boards worked. The return date was October 2017 so I am planning to salvage some of the parts and make a collage of the parts as a warning to stop buying from this supplier.

Tested several modules and NONE works! The output voltage was slightly lower than the input voltage. I've tried regulating both input and output voltage, I've tried with and without a load connected. Save your money, don't buy this junk!

This worked well for my hobby applications for example. arduino/raspberry pi and 2S lipo/8cell nimh applications. I usually output 5V or 3.3V. If you care, it has a really "high" quiescent current, ie 5-10mA, but I guess it wouldn't matter/would be anything else to most people choose if you would care. Just look at the data sheet and maybe then confirm if the claims are legal.

Works great but you need a way to get the voltage right before you start using it. It took a few turns of the adjustment screw for my boards to start registering the downward adjustment. If you ordered them and find they don't work, you may need to add a few turns of the adjustment screw before you see the reduction work. I have these little boards that work with a little USB. Camera, LED lamp and a few other small projects. Great for the price.
