Review: Great Power Supply for POE NVR System - I was having issues with my Reolink 16 Ch. POE NVR system. Sometimes when I would turn on or off my indoor lights (on a separate powder breaker) the factory power supply would cut out causing the NVR to reboot. Not sure why this was happening as I have a house built in 2019. I figured the factory power supply had an issue with a slight power fluctuation? I even purchased a UPS with a line conditioner that was rated for 20x the power the NVR drew but that did not fix the issue. This power supply has completely remedied the issue and my NVR runs smooth (I've tested everything in the house as even turning on and off my well VFD would cause it to cut out before).
Review: 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.

## Questions & Answers

**Q: I need an ac to dc converter with the following specifications: input voltage = 410v three phase ac voltage and output = 54.6vdc at 2000a.**
A: Hello,

Sorry - we do not carry any power supplies compatible with 410V input, or with an output of 2000A.

**Q: 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?**
A: Hi,  The LRS outputs constant voltage, so the current is not controlled.  The wattage output is selectable, and it can only output the wattage selected for the model.  If the load is pulling to many watts for the model selected it would go into fault mode.

**Q: Do you have any 48vdc x ~300w switch mode p/s suitable for use with servo/stepper drive.  regenerative feedback tolerant.  120-240vac input?**
A: The smps has the efficiency, so 350w* efficiency is the actual power, for servo or stepper drive, you just need to make sure the voltage is OK, usually we use DIN rail power supply for servo or stepper drive, as these motors will be used on equipment. MEAN WELL don't have 300W smps, you could choose SP-320-48, about regeneration power, please use big resistor to solve, usually servo drive has this function itself.

**Q: Is it possible to connect multiple of these power supplies in parallel to increment the output Amps?**
A: Hello,

The Mean Well LRS series is not designed to have multiple power supplies connected in-parallel.  If higher wattage is needed we would suggest the HLG series which is available up to 600-Watt.

### ⭐⭐⭐⭐⭐ A Very Good Power Supply
*by D***N on January 5, 2023*

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.
