Mean Well RD125-1224 switching power supply using a NE1101F ic chip

[sam_sam_sam]

Here is the data sheet for this ic chip it is for A or B version not for F version but the letter has to with what frequency it is using for this version

This is a dual voltage output version ( output 1 )12 volt / output 2 24 volt output

There dose not seem to be much circuitry on the secondary side of this power supply

Curiously got the best of me and I had to see how this power supply was made

Update

Well my engraving machine is happy with this switching power supply

I had up the voltage a little bit because my 24 volt output side was about 0.500 volts low

brought up the 24 volts to exactly 24 volts and the 12 volts side was about 12.5-something

which will work fine

Now I have to make an enclosure ( with the 3D printer) for end of this switching power supply because I want to cover the input 120 ac current terminals so I do accidentally touch those terminals “ safety first “

I also have hook up the controller power supply switches I still have a lot of work to do on this project

My laser ( and or ) spindle motor and engraving machine controller can all work off of the same switching power supply instead of 3 different switching power supply ( bumper)

Update

The switching power supply has been running for last 2 hours now and the voltage on the 24 volts is now it 24.44 now and now the 12 volts is now 12.44 volts which also fine because the only thing running right now is the engraving controller

Be careful when buying a dual channel switching power supply because some seller are miss interpreting the specifications of this type of switching power supply

Putting the maximum amperage for each channel and not what each channel outputs if you use both channel together at the same time but on the data plate shows the maximum output if both channels are used at the same time and does not tell you what the maximum amperage is if you use only one channel which to me is a mistake on there part

This would not take that much space on the data plate for this information really

Couple of things I forget to mention

The laser that I have with the engraving machine at 100% laser power at 12 volts using engraving controller switching power supply controller which was about 2 amps this was a test just to see if it could handle the load

But what I going do instead is use the 12 volts for the laser and have the engraving controller on the 24 volts

When I am using the spindle motor will be on 24 volts and the engraving machine controller on 12 volts side
