I have a 130w chinese co2 laser. After taking some bits apart to paint, the controller would not start. All other parts, such as laser, air, water received power. I connected a 24v adapter to the 24vin on the controller and it fired up, so I guess something on the power supply is fused/dead?
Anyone know how I can fix this? Perhaps there is a fuse or something inside the power unit?
Perhaps there is, but āthe power unitā on āa 130w Chinese co2ā is like me asking you āthe engine died in my red Japanese car. Can you tell me what I need to do to fix it?ā You might need to provide more details, model number, pictures, etc before you get anything useful.
I canāt recall if Iāve seen any with fuses - they often have capacitors or rectifiers fail in them.
There seems to be a small fuse in the DC24v supply. I imagine thatās fused? I checked the voltage in with a multimeter and itās definitely getting a power supply.
Iāve tried looking for this unit on the internet and canāt seem it find it. The smaller DC power supply under the big one. Any idea what I need to be searching for?
I think the best thing is to buy a new 24v switching power supply. The laser is supposed to be 130w but I think they sent it with a 100w tube (typical Chinese seller). What wattage of supply should I be looking for?
That machine is set up with a 40VDC supply for the steppers, so the 24VDC supply is just to run the controller. It is most likely a 5A supply, but s Oz stated, try to find a rating on it and match or exceed that.
Thanks for the answers. Itās been really helpful and Iām getting closer lol.
Frustratingly, the one on it doesnāt give too much away. It only says āDC25Vā on one sticker, and underneath it says āRSA-25D-C AC INPUT 90 - 264 vac 24V 5Vā.
For ruida controller, 24VDC 3A 75W switch power supply is recommand.
You can search for Meanwell LRS-75-24 switch power supply.
5VDC is always use for red pointer.
