60V 20A 1200W

Seems to work as described

You get what you pay for. Bought this for replacing the main power supply in a Riden 6024 power supply. It worked great the first time. Put the unit on the shelf and now it is completely dead when trying use it the 2nd time. And of course, this is just 2 weeks outside of the Amazon return window.

I ordered this power supply hoping to modify it so I could charge my 3.8 KW, 2012 Zero motorcycle (14s), battery. The description claimed it is not constant current and could not be used to charge a battery. I have not modified it yet but still use it at j1772 charging stations by setting the voltage just above the battery's voltage, connecting it to the battery, then adjusting the voltage screw until it is charging at 20 amps. I charge at LA fitness so I can walk out and raise the voltage every 20 minutes or so. If the voltage difference is too much, the charger just turns off. No smoke so far. I have used it about a dozen times this way. It does get warm and the fans are loud.

As advertised

First one smoked at 15 amp replacement almost did the same thing i had to back it down to 10 amp output for it to just smell warm and not about to let out the smoke. The overload protection does work but no thermal over heat shut down. Its got potential but the build is not complete for it to do 20 amp it needs more internal thermal dissipation. I need at least 18 amp to charge a Lithium 50 amp hour battery pack for my mid size electric motorcycle and ive got 2 electric bicycles but they are only 12 amp hour packs.. THEY NEED TO PUT IN THE DESCRIPTION 10 AMP CONSTANT AND 20 AMP MAX. Update 3-1-22 about that time of year thought ide try 48 volt at 8 amp and it shut down i suppose it does have thermal protection so in short this is useless to me to charge my electric mid sized motorcycle lower than 10 amp will take all night for a 50 amp hour battery. Im useing a boost converter for 88.2 volts CC/CV so i can supplement the power supply with a 20 amp hour 48volt battery which can handle 20 amp. Using the battery for a quick boost and range extender. The power supply MUST match the battery. Update 7-22 After taking it apart and adding thermal paste where needed and making sure the heatsinks are snug like they should be im able to get 15 amp out of it constant so far with out it smoking or shutting down but that is only at 48 volts I was attempting 60 volts before at 8 amp and it shut down before i did all the thermal paste and snugging down. Will it do 20 amp @ 60 volts sure but not with out problems and fast. The NTC thermistors (3) give up the ghost at that high rate. My battery i use for back up charge is comparable 48 volts up to 20 amp so i suppose that will have to be good enough. Added 2 stars even though i had to do something different at least it was not a total FAIL!

I'm on my 3rd from Amazon just because the overprotection keeps tripping. There are no instructions at all about how to reset it after it trips, so I've returned it each time. Hopefully this time it lasts as I'm using it at under the rated voltage/amperage. The first time I used it, I plugged it into my battery bank that I'm charging (similar to another reviewer's bike battery, using a voltage boost charger), it popped without warning. The next time I used it, I plugged in the battery before connecting to the wall, and it seemed to work fine for about 10 minutes. It seemed to effortlessly draw 16A at ~56V, but it sure didn't smell great. As I was fine tuning it trying to reach 58V, it suddenly popped and I lost all power. Will be hooking a multimeter up to the 3rd one I get and pre-setting the voltage I need out of it. Bummer that these things are so shoddy, I really need a quality 20A 60V DC charger to charge my portable power pack that I made :(

When I saw this 60V 20A 1200W power supply unit (PSU) boasting a universal AC input and a broad array of applications, I was intrigued but a tad skeptical. Its compact size and hefty power output seemed almost too good to be true for my ambitious projects, ranging from powering a custom-built workshop lighting system to running a small compressor and even dabbling in some DIY electronics. First off, the size and weight are as advertised. It's surprisingly compact for something that packs such a punch, easily fitting on my workbench without taking up much space. The promise of being able to power multiple devices with varying power needs was the main draw for me. The versatility of this PSU is impressive; it effortlessly switches between running high-demand motors and more sensitive electronic projects without a hitch. The PSU's efficiency and proprietary circuit design were what really set it apart for me. The low standby power consumption and high-efficiency claims held up during use, which is a relief for both my electric bill and my peace of mind. Plus, the aluminum shell does a decent job of dissipating heat, a non-negligible factor given the power this unit is handling. However, the claim of a "long service life" of more than 6,000 hours will take time to verify. While it's reassuring on paper, the true test will come with extended use. Similarly, the unit's safety features and build quality give me confidence in its reliability, but I'm keeping an eye out for long-term durability. The PSU's ability to power such a wide range of devices—from LED strips and CCTV cameras to more power-hungry applications like winches and air compressors—is not to be understated. It's a versatile beast, but this breadth of application does mean you need a solid understanding of your power requirements to make the most of it. It's not quite plug-and-play for every scenario, requiring some tinkering and technical know-how to get everything running smoothly. In essence, this power supply unit is a strong performer that lives up to most of its claims. It's a valuable addition to any hobbyist's or DIY enthusiast's toolkit, provided you're willing to navigate the complexities of power needs and connections. Its efficiency, compact size, and versatility make it a standout, albeit with the usual caveats of needing to approach its long-term reliability with a watchful eye.

I ran this power supply at 60V @ 15A for 10 minutes and it started smelling burnt and a bit of smoke came out. It's probably ok for lower loads, but then why wouldn't you buy a cheaper power supply.
