Step-up Boost CV CC Power Supply LED Driver

08-11-2018, 08:27 AM

I bought one of these and tried out

https://www.ebay.com/itm/400W-DC-DC-...53.m2749.l2649

400W DC-DC Step-up Boost Converter Constant Current Power Supply LED Driver GD
I bought three more of them for some other project that I have in mind

It seems to work very well the heat sinks do get a little warm but you do expect this

I will recap the board it has Taicon brand caps on it

Input 12 volts @ 600 milliamperes output 42 volts @ 70 milliamperes I will probably up the current a little bit more for more brightness as long as the LED module does not get very warm

This is going to work for the battery operated LED Yard Light that I am building

This is a test LED module that I was using I have not decided what I am going to with this LED module yet because the fixture is not water tight I might make battery operated one for inside the house

Where did you get that LED module from?

Re: Step-up Boost CV CC Power Supply LED Driver

It was given to me I have two of them with the same problem

The switching power supply has issues which I have not figured out what wrong with it
Also the power board is potted and kind a damaged it trying to remove the potting

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?

by Tynan Dill

I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

Upon bringing it home and plugging it up, it showed a standby light.

I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

The screen seems to blackout and stay black, but with a flashlight I can see the display.

With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply

by sam_sam_sam

I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

Gold 16ES led driver for use as a HV DC power supply

by speter

I bought this https://www.ebay.com/itm/315173036369 power supply to try to convert to a Tube radio B+ power supply I am wondering how to force it on to stay at it's highest voltage. Is there a way to make this not constant current? I need somewhere between 70 to 90vdc at I'm guessing 150ma. I am aware that the switching noise may cause interference in the radio, it is being driven by 4 3.7v lion 21760? cells with a BMS board. I basically want a dumb power supply for 90vdc which will have a cap for filtering between this and the 90v battery circuit

Modification to a ZD-987 desoldering/soldering station using a external switching power supply

by sam_sam_sam

I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails

I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...
