In usual, the power supply unit people talking about is the piece of hardware that's used to convert the power provided from the outlet into usable power for the many parts inside the computer case.
It converts the alternating current (AC) into a continuous form of power that the computer components need in order to run steady, called direct current (DC). It also regulates overheating by controlling voltage, which may change automatically or manually depending on the power supply. ATX power supply as example, The ATX specification requires the power supply to produce three main outputs, +3.3 V, +5 V and +12 V. Low-power −12 V and +5 VSB (standby) supplies are also required. The −12 V supply was primarily used to provide the negative supply voltage for RS-232 ports and is also used by one pin on conventional PCI slots primarily to provide a reference voltage for some models of sound cards. The 5 VSB supply is used to produce trickle power to provide the soft-power feature of ATX when a PC is turned off, as well as powering the real-time clock to conserve the charge of the CMOS battery. A −5 V output was originally required because it was supplied on the ISA bus, but it became obsolete with the removal of the ISA bus in modern PCs and has been removed in later versions of the ATX standard.
Unlike other hardware components used that isn't necessarily needed, as a printer or a 3D Printer, the power supply is a crucial piece because, without it, the rest of the internal hardware can't function.
An efficient power supply unit is a better PSU. Today RobotDigg want to show you the industrial power supplies that used in 3D Printers either personal or industrial and Pick and Place Machine, CNC Machines to function the Stepper Motors, Servo Motors and also power supply for LED strip or other lighting application and CCTV, etc. the Brick Power Adapter, Switching Power Supply.
If you post a topic in a forum as
"I'm looking for a power supply for my 3d printer and i don't know what i should use.
I have 4 stepper motors each using 12v and 1.2 amps, a heat bed and an extruder which also use 12v but need a higher amperage for good heating, 4 A4988 or DRV8825 stepper drivers. Which power supply should I get so that each of the appliances get the correct amount of power? "
There are answers
"Computer power supply (ATX)." Couldn't agree with anymore on this. "Some benefit of the ATX supply are
1. Ability to turn on/off the power supply from your software over USB
2. An abundance of 12v and 5v connectors
3. Ready made fans, fan controllers, lighting etc from the existing computer market. If you dont already have lots of fans, you'll need them!
4. Lots of old computer cables from which you can salvage connectors and solder them onto any components which dont have power connectors."
ATX power supply around 400W cost only 25USD from China, but you have to consider how to fix this power supply (square and flat :-)) in your 3D Pinter, especially a Delta Robot 3D Printer.
If you were using the RAMPS 1.4 or RAMPS 1.5 without Heat Bed, a 12V 10A or a 24V 5A Brick Power Adapter would fit your need, it's more portable and easy to get.
In the end of the power supply, let's take a view on the Switching Power Supply. Mean Well is well known brand from Taiwan, which is very similar result as linear rail of HIWIN does.
The result is that there are too many fake supplies because too many distributors. The worse result is that there are factories in China Mainland pretend as Mean Well, but the fact is that while RobotDigg launching this article there are only 2 authorized distributors in Zhejiang Province.
The only benefit of China Copy to the end user perhaps is dropping the price down. We noticed the birth of some independent brands that we are excited. RobotDigg brings such switching power supply normal, anti-water and anti-rain, power supply cabinet, etc.
