Beware that Tripp Lite DC power supplies are rated for ICS (Intermittent Communications Service) amps, and NOT continuous amps. This PR20 unit is actually rated for 16 amps continuous and 20 amps ICS rated. This is per the spec sheet included with the unit itself, but is not in Amazon's description.
I have an application requiring 18 amps, and the unit would shut down after 3 seconds. I've since ordered the PR30, which is rated for 24 amps continuous.
The unit itself appears to be well made, but I have no actual experience in usage until the PR30 unit arrives.
When I powered the PR20 for the first time, sparks flew from the vents. A wire carrying the 120VAC input to the transformer was shorting to the case. I repaired the uninsulated wire with some heat-shrinkable tubing and the PR20 worked.
When on, the PR20 continuously produces an audible 60Hz hum that can be heard from at least 10 feet away.
The PR20's output terminals are uninsulated threaded rods that extend approximately three centimeters beyond the rear of the case. An insulated binding post would be a safer alternative.
On a positive note, the PR20 continues to work after six months of continuous use. However, in light of the design and manufacturing defects mentioned above, I would only purchase another PR20 if there were no other alternatives.
I give the PR20 two stars, in part because there are lower-quality power supplies available on the market.
Seems to be lacking protection if hooked up wrong - blew up
