Current slide {CURRENT_SLIDE} of {TOTAL_SLIDES}- Best Selling in Adjustable Power Supplies
The PR570 is (essentially) a PR57 with a digital faceplate and the digital smarts that go with the faceplate. When you pop open the hood the essentials are virtually identical: 1) Isolation transformer 2) Variac coil on the secondary But where the PR 57 uses a single analog meter (with switchable functions), the PR570 has a pair of liquid crystal digital displays. Neither of these are backlit. You may wish to consider this within the context of the lighting of your bench. One feature I do appreciate in the 570 over the 57 is the current limit setting. To be accurate, it's a current trip, not a limiter like a series light bulb. However, the PR57 has just two current settings whereas the PR570 is continuously adjustable and the accuracy/granularity is excellent. The PR570 is roughly the same size as the PR57. So it will physically replace your 57 neatly without taking up additional footprint. But here's the downside: In terms of providing fundamental protections, the PR570 is only marginally better than a PR57, yet (used) the PR570 runs between two to four times the price of used PR57s. I literally waited years for this one. I bid on a dozen auctions and lost them all because I refused to pay more for a PR570 when PR57s are almost as good for a much better price. I got lucky this time and am happy with the purchase, mostly because of the adjustable current trip. But the darkness of the LCD meters is irritating.Read full review
