1440W is probably not available in the US because their PSU can’t deliver full power in the states. Crappy 110V grid…
Powerful device! 60V 30A 1440W max output under 220V AC, suitable for different situations, for US 110V version, it is 1140W
Why they have different listings of the same PSU at different prices - I really do not know 
The one you posted has 36% off, the one hoop posted has 28% off right now.
Yupper… and I apologize for the lack of communication…but it doesn’t allow me to find/select the US version of the same unit… That was what started this question. How to select that specific unit and price, but with a US configuration… I thought the question quite simple…but I guess I am not communicating all that well…
I don’t get it either…but thanks for understanding what I am looking for.
in your picture, it is the stock in Russia warehouse, only available in RU area, if you want it to be delivered to US, you need to make order in this link: Rd rd6030 montiert Set 60v 30a digitale Steuerung stabilisiert Wechselstrom einstellbare Spannung geregelte Labor tisch Strom versorgung 1140w 1440w - AliExpress 1420
Thank you for the information. But the unit is close to $50 more from that link.
Are the Power Supplies the same in the Eu or Us models. Is there a switch on the internal PS 120v / 240v
the price on the page is the right price
you mean the completely set ? there are choice to choose , if you are in EU, you can choose EU 220V plug version , if you are in US , you can choose US 110V plug version
you can also swtich 110v/220 by yourselves
The October Choice Day Sale on Aliexpress begins, here is our promotion page:
@RD_tech
Is there some kind of comparison table between the various models? Or how do I decode the model numbers? I guess it is this, right?
RDXXYYPW
XX = voltage
YY = current
P = USB control
W = WiFi control
The P are modernized models with lower ripple current. USB control should be present in all.
P series have lower sipple and more accuracy
Perfect, thank you!
you are welcome, if there is any question about our products, just contact us
