What are everyone's thought on something like this.....

Found this on the web today. It seemed to make sense to me. What do you all think?

Any problems with A/C, etc using something like this inline?

Greetings Eric!

I have a very similar device for my Overlander. I opted to go with one having a slightly higher surge supression rating, but it more than doubled the price of the unit in your link. In addition, I purchased a security lock to prevent theft while left unattended in camp grounds. So far, I have been highly satisfied with mine. I purchased mine from one of the regular vendors at the WBCCI International Rally in Sioux Falls, SD.

I think that I might have my Surge Supressor stored in my garage. If I do, I will post its manufacutrer and ratings later this evening.

Kevin

Thanks again,

Greetings Eric!

I did have the Surge Suppressor in my garage, and here is the data:

Manufacturer:

Technology Research Corporation
5250 140th Avenue North
Clearwater, FL 34620-9940

Specifications:

Model No.: 34680 - - Auto Power RV 30
Rated: 120V/30 AMP - - - 3600 Watts Maximum
With 10/3 AWG. Cord

Surge Suppression Specifications:

Lines Protected: L-N, N-G, L-G
Energy Dissipation: 475 Joules
Maximum Continuous AC Voltage <301Vac
Maximum Spike Current: 6500A per MOV
(8 x 20mS) (3 MOV'S)

Shock Protection Specifications:

Trip Time: <25 mS
Trip Current: 4 - 6 mA
Fault Indication: Light

Over/Under Voltage Protection Specifications:

Voltage Range: 102V - 132V
Trip Time: 8 seconds after sustained Over or Under Voltage
Power Restore Time Delay: 2 min. 15 sec.

I will admit the specifications didn't help me as much as the recommendations from other users of this system. I have had mine for nearly two years and am quite satisfied. I would like to have a higher Joules rating under Surge Suppression, but thus far haven't experienced any problems related to that rating. I couldn't find my sales receipt, but I believe that it was very nearly twice the price of the unit in your link.

Kevin

2 things about mov's

guys,

when mov's operate during a fault they get very hot, if a fault were to occur let it cool off before picking it up.

they also tend to explode when subjected to direct lightning strikes. or voltages way over the design limit.

if you have delicate or high value electronics in your trailer they could be a wise investment.

the mov's we use on power lines have a .22 blank shell in the ground connector that fires the ground wire off in the event it is hit by lightning, to isolate it from the circuit! one use, then replacement is required. job security fer us linemen!

Thanks for the info guys. I took a look again at the one I posted and it is also from Technology Research. Outside of a few extra features, it looks like the one you have Kevin also not only seems to protect against surges, but possible brownouts as well.

I sent the company an email asking for more technical specs on the two 30a units.

You mentioned something about a lock, I could not find anything on Tech Research's website:

Regards,

Eric

Greetings Eric!

I dealt with a vendor rather than direct with the manufacturer, so do not know whether the lock was actually manufactured by Technology Research Corporation. The instructions indicated that it was for securing any type of 30 AMP RV style extension cord or device. I know that I still have the original box, instructions, and packaging; but all of that material is in my trailer. The lock is steel, and has two halves that link together and are secured by a heavy duty padlock - - it basically secures the end of the trailer's power cord to the Surge Suppressor. My Trailer will be in Cedar Falls, Iowa for a period of time so it will likely be about a month before I will be able to get to that information.

I bought a SurgeGuard 30 amp (CampingWorld) which looks a lot like that techresearch thingy. To protect my electronics and electrical after we spent a night in a campground where the stereo went off and on, and the air con cycled over and over.

I purchased an in-line one, with the idea of wiring it in under the bed near the access door so I could see what's going on. Then it would not be liable to be stolen like the outdoor one. It was cheaper too.

HOWEVER,

I read a letter by a person (in an RV View magazine) who had a fire in his
electrical compartment. It was the Surgeguard which caught on fire from a large voltage spike (poss lightning nearby?) It protected his trailer electrical, but sacrificed itself and put a black hole in his RV side. There was a picture of it.

Well, if that is what can happen, and I don't have an electrical compartment, then I don't want it under the bed, so I quick
sent it back and purchased an outdoor one with a locking hasp.
Better a fire outside than inside, I always say.
