As far as the power restoration delay time, I'm good with 136 seconds. More time to diagnose the problem and react. 15 seconds is a bit short.

React to what? If the EMS sees something it doesn't like it simply won't pass power on to the rig regardless of whether delay is 15" to 136" ... you have all the time in the world to decide what to do about it, based on the what the error code is telling you. I mostly leave mine on the shorter 15" setting because we don't often use A/C and therefore don't have frequent need to protect it's compressor and I find the shorter 15" delay much more convenient, especially when I'm working on the trailer and am repeatedly applying and disconnecting power to it. A shorter delay is also more convenient when camping, for obvious reasons.

Thanks for the responses, but I was looking more for a review from someone who actually owns one, on the unit's actual performance. How easy they are to read and diagnose issues, how they reacted when faced with a problem, or didn't, when called into action. That sort of thing.

I do own a Progressive 30 amp EMS, a hard wire EMS-HW30C which as I mentioned operates exactly the same as the portable version, other than the portable's delay is fixed at 136" because it's a sealed unit. There's really no "diagnosis" per se as the displayed error code will tell you what the error may be and it's previous error code function will tell you what error may have occurred, say while you were away from your camper. What other than that do you want to know?

React to what? React to what caused the surge protector to interrupt the power in the first place. Unless you like to sit in your trailer and watch the lights go off and on while your power gets cut and restored every 15 seconds.
I'd like to know what the root cause was, based on the codes passed or stored in the unit. I'd like to know if the power problem that caused the original (and any successive) fault(s) is something in my wiring, at the post, or in the general area of the campground, the likelihood that it was a one time event, or if it's going to persist.
The surge protector tells you what it saw, and what it did about it, not where the problem actually lies, whether it will persist, and what's being done about it.
Or as I suggested, do you just sit in your trailer in the dark waiting for the power to come back on?
I'd also like to know if your PI surge protectors have ever failed to react, and were they ever damaged by a fault event.
You know, useful info.

Obviously no EMS can tell you if a fault causing it to disconnect was caused by at the campsite post or whether it's a campground wide problem or may a regional problem affecting areas beyond the campground, nor obviously can it tell you "what's being done about it". :S Any error code displayed does tell you what the problem was with the incoming source power it saw and therefore why it either refused to connect in the first place or why it later disconnected. Third, no EMS has any control over whatever may happen after it such as "something in my wiring" ... obviously if you want it to monitor your incoming source cable then that cable needs to be in front of the EMS, not after it as normally would be the case in a portable application. Fourth, no the two I've owned have never "failed to react" nor have they ever failed. A significant surge, such as a nearby lighting strike, will most likely destroy the MOVs but they're replaceable, though the portable sealed version must be returned to Progressive for repair, with the hard wire they'll just mail you the parts since it's a field repairable device.

Useful enough? :R
