Hi feathermerchant.

Thanks for sharing your knowledge. I have a special question about the 42A supplies. Why are you soldering this wire? I saw in other threads that an outside connection of two pins is also necessary.

I sold one 24V setup with one power supply isolated this way. It is just too much work considering how many 47A 24V setups I sell.

Hi there Feathermerchant,

I just ordered the 24V PS and I would like to find out if I can get the quiet version?

I've been following this thread for a while and appreciate all the effort and energy you put into this. I finally made it to the 6S club and I really need your service.

Thanks either way!

@ feathermerchant


I'm converting a server power supply and the ac voltage reading from the neg to the case is approx 5 volts but If you ck the continuity from the neg to the case there is no connection while running or in the off state. I have isolated the board with nylon washer and screws and with the power off checked the continuity from the neg to the case the there is no continuity.
Why when running it would read/show 4-5ac volts with reading it from the neg to the case?

If you do not have it tied to ground or some other fixed potential like the 12V output of another power supply, it will "wander around". We don't isolate the ground except when we need to. Then we connect the output to another supply giving it a reference.

Is that ok or is there a danger of getting shocked?

When you convert 2 12v 900 watt to a 24v what would to wattage be? The same or double?
Just making sure before pulling trigger on two need a second opinion...

Double.

You have doubled the voltage but the current is the same.

You will have a 24V 1800 watt supply.

Planekiller - Looks great. I really should build one.....

Lunker - The 75A are an recent addition to my website. I have been using them as well as a few buddies at the field with no problems. They have temperature controlled fans and a lot of power available. 75A when connected to 120V and 100A when run on 240V.

Ever notice bad news travels fast,
Good news never travels.
I'd like to share my recent purchase experience with "feathermerchantrc" with you all.

IMPRESSIVE.
Great customer service. Takes the time to answer all, even if silly, questions/emails and helps you select the correct power supply for your needs. Great build quality, great packaging and fast delivery.

All to often suppliers are not given the credit they deserve for great customer service and great products they provide us.

Thank you and keep up the good work.
