Have a Question? See What Others Asked

I need an ac to dc converter with the following specifications: input voltage = 410v three phase ac voltage and output = 54.6vdc at 2000a.
Does this supply limit output current to its max rating, or will it go into "hiccup mode" if the load tries to pull too much?
Do you have any 48vdc x ~300w switch mode p/s suitable for use with servo/stepper drive. regenerative feedback tolerant. 120-240vac input?
Is it possible to connect multiple of these power supplies in parallel to increment the output Amps?

Bought for work

I gerrymandered this to replace a custom power supply. So far, it works great. It isn't getting hot (load is way below power supply limit). I'll be buying more

A Very Good Power Supply

Meanwell supplies are some of the better power supplies that can be obtained. This is no exception. I needed this supply to replace a different one used to power a starlink dish. The starlink dish uses PoE++ @48V-52V and up to 150W. I tried using a cheaper supply but it lasted only a couple of months. I replaced it with a different (but cheap as well) supply that lasted 4 weeks. I should have simply used this supply from the outset.

Nice, but fan is fairly loud.

Worked well, was easy to connect to.For some applications the temperature controlled fan might be a bit loud.

I killed one with a load-side voltage spike

I'm using a few of these to power some large-ish stepper motor drivers, which usually pull no more than 2 amps. Overall, these PSUs have worked fine, but I should point out that I managed to kill one of them when the load itself generated a large power spike, and I guess the PSU's OVP failed to protect itself.I had been fighting an issue where the stepper driver seemed to be triggering its own overload protection, and this caused a large voltage spike on its input rails, which then back-feeds to the output rails of the PSU. This is certainly no fault of the PSU, though it did usually cause the PSU to trigger its own over-voltage protection and go into shutdown until I power cycled it. From the perspective of this PSU, that's working as intended...Except one time, I guess the PSU's OVP didn't work, and it killed the PSU. I didn't have an oscilloscope or multimeter attached to the power rail at the time of the failure, so I'm not sure how large of a voltage spike it experienced, but most of the previous voltage spikes that didn't kill it were around 70V... so I'm guessing north of that.I made some effort to disassemble and diagnose the failure, and I *think* I traced it down to the switching regulator IC. But these things are cheap enough that I didn't bother fixing it and I just ordered another one.

seamless power delivery

When I asked around in HiFi communities about using this power supply with my audio amplifier, many were hesitant. It’s widely accepted that linear power supplies are the best option for audio equipment, but they are very expensive.My amplifier offered the choice of coming with a switching power supply or none at all. I decided to take a chance and pair it with the Mean Well power supply, and I couldn’t be happier. After a month of use, I’ve experienced no issues—there’s absolutely no hiss, even when the music stops and the amp is turned to the max.The power supply remains cool, never getting even lukewarm. For me, this works perfectly, and it’s a cost-effective solution.

Works

Does exactly what it’s to do. Stays fairly cool even under pretty heavy load. If you need a power source don’t take a chance and get meanwell, they really are the best for the price.

No current flows?

Based on my greater than average electrical experience, all that should be required to charge a 42 volt lead acid battery bank is a DC source that is greater than 42 volts. This 48 volt (adjustable) 07.5 amp power source SHOULD charge the battery pack. I'm curious to know why it doesn't.Is the circuitry purposely designed to shut off when connected to a voltage source, even if the source is less than the set voltage of the LRS-350-48. ie: 48 volts.Curiously, current (amperes) flows normally when connected to a dead resistance load, such as a heater.Can anyone help me understand why this source shuts down?

Execelent reputation PSU brand

I trust the Official Mean Well PSUs for all my electronic projects. There are a lot of "clone" Mean Well PSU in the market and I would not use them as they are of questionable quality and could be unsafe for operation.
