Introduction To Work Bench Power Supplies | SciWorx Electronics

If you are a into electronics, you will need a DC power supply for everything; avionics, ham radio, Raspberry Pi/Arduino or any DIY electronic project. Here I review the basics as I unbox a MFJ 4035MV power supply.

A power supply is an electrical device that supplies electric power to an electrical load. The primary function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters. Some power supplies are separate standalone pieces of equipment, while others are built into the load appliances that they power. Examples of the latter include power supplies found in desktop computers and consumer electronics devices. Other functions that power supplies may perform include limiting the current drawn by the load to safe levels, shutting off the current in the event of an electrical fault, power conditioning to prevent electronic noise or voltage surges on the input from reaching the load, power-factor correction, and storing energy so it can continue to power the load in the event of a temporary interruption in the source power (uninterruptible power supply).
All power supplies have a power input connection, which receives energy in the form of electric current from a source, and one or more power output connections that deliver current to the load. The source power may come from the electric power grid, such as an electrical outlet, energy storage devices such as batteries or fuel cells, generators or alternators, solar power converters, or another power supply. The input and output are usually hardwired circuit connections, though some power supplies employ wireless energy transfer to power their loads without wired connections. Some power supplies have other types of inputs and outputs as well, for functions such as external monitoring and control.

So were you like, studying me that whole time we worked together so you could make this video? HAHA! Great video!

LOL. No, actually this power supply is for another video on electrolysis. I ordered two Hoffman Apparatuses - one for DC electrolysis and one for AC electrolysis (Puharich method). The glass part of the apparatuses arrived broken so I am awaiting replacements from the manufacturer. Anyway, I didn't have a power supply for the DC electrolysis and that is what this box is for. As I wait for the replacement glass, I thought I would do a review of the power supply.

@Randy Welch, Sage I haven't been to a field day in forever it seems.

Personally I would prefer a PSU with adjustable current setting.

[@SciWorx]

This is how I end up with so much gear!!!!

[@plane-fuzz]

High voltage Direct current and solid steel bench oh it could get jiggy. (hot gloves might help)

[@SciWorx]

Also, VERY well grounded!
