I'd subscribe to a channel that teaches how to wire stuff. I want to make a simple circuit with a few switches, USB ports, 12V cigarette plug, a battery and a way to charge the battery. I have no idea where to begin!

@041e71 3 года назад

Two important things that I am missing in this video (pls upvote, so everyone sees this). - STRAIN RELIEF: Definitely make sure you have some kind of strain relief installed, that prevents the mains cable from disconnecting when someone pulls on it (e.g. when stumbles over it). A cable tie attaches to a strong part of your casing could be enough. - PE Wire: If you use a metal casing for your project you need to connect PE-wires to all metallic case components. This ensures that the circuit breaker trips as soon as a loose live wire touches it so there is no mains voltage on the case.

@jfan4reva 2 года назад

I hope he hasn't burned anything down with his power supply yet. I'd highly recommend putting a power switch and a fuse on the AC side so that if the power supply ever does start to smoke, the power can be cut without having to run to the end of a 20 foot cord to unplug it, and no one will get electrocuted by touching it. Adding a switch and fuse is ridiculously easy. There are many IEC power cable sockets available with built in fuses and switches. Get one and you won't have to chop up a perfectly good power cable! You'll still need some wires to run from the socket to the power supply, but wires are cheap. You'll also need to buy some crimp connectors and a crimping tool to make the connections, but they're cheap also. Don't mess around with 110/220 volt AC connections. Don't cut corners. Do it right. Adding a fuse greatly reduces the chances of a fire both in the power supply itself, and in the AC power circuit the power supply is plugged into. No electrician would ever wire up a power supply like this. It would be a violation of most electrical codes it they did. 110/220 volt AC circuits don't care if you're a pro or an amateur, If you do things wrong, eventually there will be serious consequences.

I'd buy a rocker switch with fuse. He wouldnt have needed to cut his computer cable. Look on Aliexpress or Amazon for a IEC320 C14 rocker switch with 10A fuse. They're the best way to to power on a power supply so you dont start a fire.. especially if you have a cheap chinese power supply.. Cheap chinese power supplies have been known to catch on fire. You can google that and see all the images people uploaded. Rocker Switch with a fuse from the Mains power to Power Supply and a Solid Sate Relay(SSR) from power supply to your device/controller if you really wanted to be safe. If you get a relay.. dont buy it from China.. they too catch on fire since they sell fake SSR. In Oven Garage's case he would want a SSR to protect his LED controller(the Arduino Microcontroller). Some people will think its just 5V.. but lower voltage means higher Amps.. Regardless of volts and amps.. electricity can cause fires if ran thru inferior products. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-DxEhxjvifyY.html

I got a question.. Now i got 2 power supply 12v both is same 50a... Can i combine together for powered 1 amplifier to get 100a output?

I don't think so, unless you split the device load into each power supply somehow.

You can. You have to connect the power supplies in parallel. You can google that. I think its not worth the trouble though. You have to make sure both power supplies are up to par and dont fluctuate.. if one power supply drops or dies the other power supply wont be able to power the device or can cause the power supply to burn out depending on what youre powering. Youre better off just getting the proper Amperage power supply for the device. The rule of thumb when it comes to engineering is the more factors you add in to the equation, the more you increase your chances of things to cause errors and fail. The harder it is to troubleshoot to. This is why the saying K.I.S.S. (Keep It Simple Stupid) came into existence. Humans tend to over-think problems or go over-board with their solutions and end up shooting themselves in the foot. www.eevblog.com/forum/beginners/can-i-connect-two-power-supplies-in-parallel/
