Has anyone out there tried Wantai Motors Power Supplies...?
I'm struggling to find something rated a 50 Volts DC at 17 Amps Here in Australia...

I've made contact with them and just want to see if anyone has used them before...
They are quite cheap...
2 x 400W - 48 @ 8.3 Amps - $39USD per item...
Need someone to point me in the right direction...
:wave::wave::bs:

I suppose I should have left a few calculations in my last post...
My intention is to build a new machine
2 motors running the X axis - due to its size
1 Motor for both the Z and Y axis'

Have purchased
4 x Gecko 203V
4 x Nema 34 640oz/inch Steppers
50V Max
6.3 Amps per phase
2.2 mH Inductance

Still yet to purchase Power Supplies...
Calculations as follows

Max 50V = 32 x Square Root of 2.2 = 47.46V
Amps = 4 Motors x 6.3 Amps per phase x 0.67 = 16.88Amps

Options I have at this point looking to purchase -

2 x Wantai Motors 400W 48V 8.3 Amp Power Supplies to run 2 motors off each...
OR..
1 x Keling Industries KL- 5020 50 Volt 20 Amp Power Supply and run all off this one supply...

Question is...? Whats the difference between the Keling Industries KL- 5020 unregulated power supply as to the regulated Wantai Motors power supply...

Is the extra amps from the Keling Industries KL- 5020 going to matter... I may add a 4th axis to the machine in the future... Also the Keling Industries KL- 5020 has a second 5 volt output hand for Fans and BOB...

Cost wise - Wantai can supply me with 2 x 400W supplies and a 5 Volt 15W supply including delivery to my door for less than the cost of the Keling Industries KL- 5020 by itself...

Opinions and expertise would be greatly appreciated...! Are my Calcs correct...?

Hey coloradonewbie...

Thanks for the recommendation.. However I opted for the Keling KL-5020... Going by the gecko site they recommend unregulated DC power so I stuck with that...
I did chat with Jolie tho... Its great that you can chat live with them right there and then... Saves waiting on replies to emails...

The Keling KL-5020 arrived today... Looks cool... Just gotta figure out how to wire it up...

Anyoe know of a link that would show this...?
Cheers

Here you go. I know his site by heart...PSU Docs

Hey FannBlade...

Thanks for the link... I don't suppose you would know which wires are paired...
I'm wiring for 220VAC
The document you showed us states...

220Vac – 1st red wire to neutral, 1st black wire to 2nd red wire, and the 2nd
black wire to hot.

You wouldn't know which is which would you?...

[FannBlade]

Sorry I can't help you there. Just getting started in my CNC venture. I'm also looking at that power supply,let me know how it works out.

[Eddymeister]

No worries mate... I'll let you know how I go...
I might just chat to John from Keling and see what he says...
I'll be building mine over quite some time but I'll keep you posted...
Cheers
