High Current Variable Power Supply?

[bos10]

I need to buy a high-current bench variable power supply. The 40 Amp Manson SPS 9400 was recommend by the manufacturer, but I can only find that model in 220v and I located in the US, so I need 110v. I have the following questions:

(1) Is it OK to use a switching rather than a linear power supply for RC use (i.e., powering components while on the workbench, supplying power to my 12v battery charger, etc.)? I know that the linear is better, but they cost and weight about twice as much (the 40 amp one that I’m looking at weighs 70 pounds).

(2) Can you recommend a manufacturer/model? I’m looking at MASTEK and TEKPOWER at http://www.radios4you.com/powersupplies.html.

Thanks in advance,
Scott

Scott,
I'm not sure what you mean by High Current Variable Power Supply but have a look at this.

This should give you what you need for bench testing, if not then search the site to see if you can find something more suitable.
