Any way to quieten meanwell power supply?
Where do you guys get your banana jacks for your chargers?
Also, I just got my meanwell 24v 1000w p/s mounted and am looking to make it quieter. The fan sounds extremely loud. Is there a quieter power supply with similar power, or is there a way to quieten the meanwell? Thanks. Last edited by txbonds; 05-09-2011 at 04:16 PM.. |

If you need banana jacks they have them! Good quality too.

Changed question in first post regarding noise of power supply. Thanks for any help

They are loud because they need the cooling. The only way to make it quieter is to reduce cooling and that may cause heat problems in the unit. Welcome to industrial grade units.

Thanks for the response. Have you ever tried the voltz or icharger 350 watt units? Are they quieter and could they be used in parallel to achieve 30v output since they are 15v each? I realize they would be less wattage, but I could probably get by just fine on 700 total watts as opposed to 1000 if it made a huge noise difference. |

They are very nice units for sure, and they can be used in SERIES to make 30V.

I don't own a Meanwell unit, so I have no idea how loud they are. The P350 is silent when under a low load, fan stops, and makes a moderate sound at full fan speed.

My meanwell sounds like a server room. Very loud. Any difference or preference between voltz or icharger's 350 supply? They look to me to be the same other than label |

Junsi makes both, they are exactly the same units.

I run a meanwell and I don't have an issue with the noise as I fly / charge outdoors. I actually tried to put a quieter fan on it and it wasn't getting enough air flow so I put the stock fan back on. I love the 1000 watt, 26v, 41.2 amp output for my powerlab 8!!

The thing I like about the icharger 350 is it says fan is temp controlled versus always on like the mean well. Other than the noise the mean well works great though. So I guess I'm giving up power for quietness. Should still have 700 watts but more volts, so I'm not quiet sure how the charge capability will compare. Anyone know how many 6s batts I can charge at a time this way? |

With my meanwell and powerlab 8, I can charge a 12s setup in parallel in about 15 miinutes at 3c which is the recommended charge rate for the Spyder 6s, 5300 mAh packs.

Your power supply is going to be louder than normal as it is mounted on a soundboard. If you can isolate the PS from the side of the metal cabinet it will be quieter.
Another consideration; switching power supplies have fans and are louder than conventional power supplies (ie, with large transformers). My 320 watt supply is built to power an HF radio transceiver. No fan and no noise. The downside is that they are heavier, larger and more expensive.

I know the cabinet doesn't help with the noise. I have a 1/2" piece of pine board on the inside of the cabinet to add some mass to the metal. The bolts run through that but I'm sure adding some sound deadening material and a board outside would help increase the mass further to reduce sound.

Just noticed the prc500 at progressiveRC. Could 2 of these be used in series to get 30v and 1000w and any one know if their fans work like the voltz/icharger 350's? The look similar in design.

Spoke to Dave at progressiveRC yesterday and he indicated it was not recommended to run the icharger 350 nor his own prc500 in series as it isn't designed for this and would be unsafe. That said, either or on it's own would work but won't have the power output of my meanwell.
Looking into the sound I think the above poster is right in that if I take it off the cabinet side it will be a little quieter. Does anyone think it would be a bad and/or unsafe idea to mount it underneath my wood workbench top? It would have plenty of airflow and clearance for air cooling, but if something went wrong it would be sitting directly against a wood work top. The only other thing I could think of was maybe to put some sort of barrier between the powersupply and wood that would create a fire barrier. Any thoughts on this as it holds promise for reducing my sound issue. Thanks. |

I installed a PC fan controller. It's simply a potmeter that is soldered between the fan and the fan output on the electronics board.
With this, I can reduce the noise a lot without increasing the temperature more than a few degrees. |

Just remember that noise = fan speed and fan speed = air flow. If you slow the fan down at all, you are lowering the airflow. Now what in impact that has on the unit will depend on many variables including load, ambient temp and such.
Your best bet it so move it somewhere where it still gets good airflow, it close enough to keep the output leads short but is not in direct ear-shot.

Thats why I was thinking of moving it below the maple workbench top. I could screw it directly into the wood using the off set brackets I'm using now to mount it. Would keep it so that air could flow on all sides. My only concern is if it did ever go poof it would be hanging beneath a large piece of wood, but maybe it's rare that these things go poof? |
