AC to DC Converter 60V DC Power Supply Adjustable 0-60V 0-10A SMPS Max 600W Switching Power Supply for Led Strip, Motor Pump, CCTV, 3D Printer, Lab Computer

I hooked it up to replace a tried and true power supply that delivers 12v up to 40A, so I dialed this new unit to 12V, when under the same load, the voltage dropped down to 2 to 3V while only putting out up to 6A. Sad!

I am using this supply to charge a 48V battery and adjustable voltage and current are essential. I read one review that stated the current regulation was more of a "tripping the protection circuit". I didn't have any such issue driving a resistive load and the current was adjustable from 0 to 10 amps. Once reaching its limit at about 10.1 A, it just remained at that level without shutting down. One nice feature not mentioned is the voltage and current potentiometers are multi-turn so it's easy to set a precise value. The built-in multi-meter is accurate to within 0.1 unit. I set up a bench test to charge the battery and it worked as planned. I adjusted the power to be about 70% of the supply's stated capacity. Having passed this test, I set the supply on top of the battery cabinet and connected it to power. Without being connected it to the battery, I switched on the supply and rotated the chassis so as to rest on its side so I could easily see the display. As soon as I rotated it, there was a bang and flash then nothing. I took the supply back to the bench and powered it as before and it was dead and not drawing any power. I assume there must have been some solder scrap or something conductive that caused a short when I rotated the supply. Maybe it doesn't like 230V input. Fortunately, the case was electrically grounded and I felt no shock even though I was holding the case with bare hands. This supply is exactly what I need to charge batteries. The supply seems well built and worked as described. I hope this was just a fluke so I am going to get a replacement and try it again. I will update this review when I get the new supply and put some time on it.It's been a week on the second supply since the first one failed. I'm using it at about 70% of its rated capacity of 600W and so far all is well. I raised the overall rating from one to four stars still considering my experience with the first unit. After purchasing this model, I noticed that Bosytro offers a similar 60V/10A model that currently is discounted. It features a terminal strip for input and output connections and the control potentiometers appear to be larger and of a more typical style for multi-turn pots. For anyone interested, I measured some 2-Vpp noise spikes while operating at 50V/8A output which is to be expected from a switching supply. The spikes are fairly high frequency and should be easy to filter if it is a concern.

The media could not be loaded. I purchased this device with the hope that because it had both a voltage and current display. It would be a simple to use and easy to work with unit. Love the NEMA plug and the Multimeter. However, when you have two large bare aluminum rods carrying up to 60 VDC and 10 Amps you are asking for trouble. But using heat shrink to protect them, I can get past that. What i can't get past is that the unit absolutely goes bonkers when its current limit is reached. Ether bouncing all over the place from zero back to full voltage and down again or simply tripping the protection circuit and cutting the output until you power cycle the device.Again i understand an over voltage or over current event is dangerous however clamping down the power rather than limiting the current wasn't the best choice. As you can't adjust the current while it is under load or you will trip the protection and have to power cycle.If you are ok with that then its not all bad but it is not a bench level power supply in any sense.

I tested this product with a quality voltmeter and the readings on the supply matched the voltage on the meter within a few hundredths of a volt.I also tested with a 24v fan and it tested fine as well.The connectors it comes with are well made, the alligator clips are not cheap plastic but metal instead.

Cheap chicom that only runs about 1/3 of its continous rating. Burned out two of these units running 1/3 continous for oy a few hours a day.

The media could not be loaded. As seen in the video, when a 10A load is connected to the power supply, the output voltage fluctuates by 25%. This supply has a hard time with transients! I would not recommend connecting this to a battery or any other electronic device, you could very easily damage something with the sloppy regulation. It will work for my purpose (anodization) but I would not recommend otherwise. Do not mess with this thing unless you know what you are doing!!

.This is the nicest bench power supply I have used. I've used a lot and built some of my own.It's a clean unit. Good range of voltage and current that can be adjusted easily.Certainly a good value for the quality offered. Necessary accessories are included.
