12-18V DC automatic polarity selector schematic
$10-30 USD
Оплачується при отриманні
Need to develop the 12-24V DC automatic polarity selector/switcher schematic, to automagically switch the polarity of the input Square wave signal (4 channels), to the requested polarity.
For example if the INPUT signal polarity is reversed, it will be automatically reversed back to the "normal" polarity so the device will be powered by correct polarity.
Please note that because target PCB is quite small, so a simple "relay method" is not an option because of the big size.
Design must be compact very, yet withstand 18-24V 3A work for up to 8hours in a row, without overheating.

Hello. I'm interested in yout task, and I have one solution m if your selector works and low frequencies. Please write in chat and we can discuss details about it, maybe modify sch or acceptable that I already have. Vi Більше
Hello, how are you? I have read the details provided, but please contact me so that we can discuss more on the project. I don't outsource like most people do ensuring quality work on time
Hi, I would recommend a simple bridge rectifier. It is the same used for transforming AC to DC signals. The choice of the diodes depend on how much voltage drop you can afford (1.2V at the cheapest solution). Більше
Hi, I'm a electrical engineer with experiences in the dsign of electronics products like UPS,VFD, RF energy harvesting system with interations from android to this product.
Dear, We will prepare schematic in ORCAR Capture and will provide you pdf files too. We will use Proteus software for simulation. Looking forward to your positive and swift response. Regards, Syed Nasir
