Excellent Power Supply

Review by Reuben on 6/19/2016

My old power supply burnt out, the beam slowly lost power over about 60 seconds, and I needed a replacement quick. I ordered this one because I ordered several times from Lightobject and their parts are solid. They had my order out the next day as I also upgraded to overnight shipping. I ripped out my old power supply out, installed this new one, and was back to cutting in mere minutes! It has been a few months since I installed the power supply without any indications of issues. Very happy, thanks.

Anyone looking to purchase this power supply can do so with confidence. Although I have not yet powered it up, it is clear that this is a well made power supply. It shipped quickly and was very well packed. The only option I would have liked it to have would be a potentiometer input for PWM control.

Great Power Supply for eBay 50W Laser (Shenhui SH-G350)

Review by Robert on 10/26/2018

My 50W eBay laser suddenly stopped cutting one day, so I ordered this power supply, received it 2 days later, and installed it. It works great so I am back up and running. A few things to keep in mind: 1. It comes with the plugs, which is great. The 6 pin connector was identical to the one that came with my machine's power supply and was wired identically, so I could just plug it in. However, the 3 pin connector was larger, so I had to disconnect the 3 wires and screw them into the LightObject supplied plug. Not a big deal, just remember not to misplace the plugs! 2. The positive (red) and negative (white) are hardwired to the power supply. The positive is quite long, so shouldn't be an issue, but the negative is short, which means you will have to jumper it to another longer wire.
