Re: [Elecraft] OT Power Strip suggestion.

[Jim Brown]

Unfortunately, the most commonly "thought to be the best" surge 
protectors often CAUSE destructive equipment failure.  These devices use 
MOVs to conduct the surge to the Green wire, and that ANY surge 
protector that does that raises the voltage on the chassis of the 
equipment to a VERY high level. When that equipment is connected to 
equipment plugged into a different outlet, the DIFFERENCE in potential 
between the two pieces of gear is very likely to fry circuitry in both 
of them.


The ONLY safe place for MOV protection is at the service entrance -- the 
"whole house protector."  The only safe protection on a branch circuit 
(that is, anywhere else) is a SERIES MODE protector. Series-mode 
protectors store the surge in a big inductor, then slowly discharge them 
after the surge has ended. They are widely used in pro audio systems, 
which have many interconnections between equipment. That industry uses 
protectors made by Surge-X; a company called Brick Wall is a competitor 
that focuses on the home entertainment market. I use Surge-X units in by 
home, office, and ham station.


I've done consulting work and technical writing for Surge-X, but I was 
specifying their products for the large audio systems I designed at 
least ten years before they hired me for technical writing and teaching 
at industry trade shows. In other words, my recommendations are 
professional, not based on a business relationship, and I haven't done 
anything for them for about four years.


There are more detailed tutorials about this on my website.
I wrote http://k9yc.com/SurgeXPowerGround.pdf

The next two links are for a 4-hour tutorial workshop that Andy Benton 
and I taught at Infocomm for 6-8 years.


Andy and I collaborated on
http://k9yc.com/InfoComm-PowerSystems2012.pdf
and the material on surge protection is Andy's work.  There's nothing in 
it that I disagree with.


This one is all mine. http://k9yc.com/InfoComm-Grounding2012.pdf

This slide deck focuses on our ham stations. It served as much of the 
basis for N0AX's excellent ARRL book on the topic.

http://k9yc.com/GroundingAndAudio.pdf

Bottom line -- proper grounding and bonding is FAR more important than 
surge protectors. Good surge protection isn't cheap, but cheap surge 
protection is more likely to CAUSE equipment failure than to protect 
against it. If you don't want to spend the bucks, do the proper 
grounding and bonding, which is, essentially, free. The "whole house" 
units take care of strikes coming in on the power line, the branch 
circuit units take care of what's picked up on wiring within the house.


The whole house protector I'm using is made by Joslyn. I didn't do 
research to find it -- a fellow ham bought some at a good price and 
offered them to me. It's a high quality unit.

Re: [Elecraft] OT Power Strip suggestion.

[Bob McGraw K4TAX]

Invest in a whole house surge protector.  Sometimes called secondary 
surge protector or arrestor.    It is installed at the breaker panel, 
preferably by a licensed electrician.  These are available at electrical 
supply houses and big box hardware stores, Lowe's, Home Depot, Minnards 
and such.    Usually cost about $25 to $45.


From lightning surge events, be sure all services, i.e. Cable, 
Telephone, Electrical, and ham radio equipment grounds are ALL bonded 
together outside of the house.    Single driven grounds, not bonded to 
all others, are an invitation to trouble.  Besides, it is a requirement 
of NEC.

Re: [Elecraft] OT Power Strip suggestion.

[Bob N3MNT]

In keeping with the previous comments you may call your power company.  I
have a whole house surge protector at the service entrance provided by power
company on a rental basis.  it works pretty well as we have lot or surges
due to storms and above ground wiring.  The best part is they also provide
insurance so that if the protector does not do its job, they will repair or
replace the damaged device.  Had one stereo amp damaged and they paid to
have it replaced.  You can also purchase a whole house protector yourself,
but you usually don't get the same level ( or any) insurance.

Re: [Elecraft] OT Power Strip suggestion.

[Walter Underwood]

The Wirecutter has an excellent article (with recommendations) on surge 
protectors.

They have teardown photos, explain their testing methodology, and go into 
series mode protectors (SurgeX and ZeroSurge) and whole house protection. They 
have some nice graphs comparing SurgeX and ZeroSurge.

https://thewirecutter.com/reviews/best-surge-protector/

"Our top pick is the Tripp Lite TLP1008TEL because it stops passing power to 
your devices when it’s no longer effective at blocking surges.” ($25 from 
Amazon)

“[…] we added the Furman Powerstation 8 as our upgrade pick after it 
demonstrated the best surge suppression of all the models we tested [….]” ($127 
from B&H)

Re: [Elecraft] OT Power Strip suggestion.

[brian]

Reed,

The last sentence about having to reset is true for some units and not 
true for others.  You can find those that automatically reset.  They are 
a bit more expensive.


https://community.spiceworks.com/topic/1525772-ups-power-state-after-power-loss-and-battery-depletion 



"As batteries begin failing, automatic restart back into a protected 
operating mode when power is restored becomes more challenging for the 
UPS to provide.  You can overcome it by ensuring that your battery set 
is frequently tested and replaced well before failure.


What else can you do to ensure that your application will restart 
automatically when power is restored?


Get a UPS with BATTERY INDEPENDENT RESTART ability.  UPS systems that 
include this feature will restart back into a protected UPS-enabled 
operating mode when power is restored, so long as batteries are in 
good-enough shape to provide protection.  If batteries aren't in 
particularly good health when power is restored, a UPS with BATTERY 
INDEPENDENT RESTART will automatically begin passing BYPASS OUTPUT to 
power your connected equipment right-away after power is restored, 
regardless of the condition of the battery set.  While bypass isn't a 
protected operating mode (it won't provide UPS protection), it's better 
than nothing!  This allows your applications to begin operating right away."

Folks,

Thank you very much for your helpful 
replies. I will have a whole house 
protector installed. I need to review all 
the links and companies you kindly 
provided me with and make the purchase.

I have an older Staco Energy UPS I've 
never used, bought it at Dayton a couple 
years back. Weighs a ton from the lead 
acid batteries inside, need to put another 
plug on it, it comes with a 30 amp 120V 
plug and the house wiring doesn't support 
that. I need to find an owners manual for 
it as well, looks like there is a USB port 
involved & it didn't come with a manual. 
After getting the whole house protector I 
should probably attach this to the stereo.

Thanks for all the helpful replies.

Virtually all UPS units include MOVs, so have all of the destructive 
possibilities of MOV power strips. If you're going to use a UPS (and I 
do), it should be plugged into a shunt-mode surge protector (SurgeX, 
Zero Surge, or Brick wall).

Re: [Elecraft] OT Power Strip suggestion.

[Dave Sublette]

I have just had a most unfortunate experience with a UPS and when Gary said
he had an old UPS he was considering, I shuddered.  As far as I know, older
UPS units overcharge the battery continuously.  The best "problem" this
seems to cause is having to replace batteries every three years or so.

In my case, the battery not only was overcharged, but the UPS died in such
a fashion that the 117 AC was interrupted several times and that killed my
computer, which it was supposed to protect.  I know the house current did
not flicker or drop during the time.  It was strictly the UPS.

I have replaced it with a modern unit that has a selectable "float voltage"
for several types of backup batteries.  In my case I selected a 100AH deep
cycle AGM construction unit.  If the house supply goes down, it switches to
a 60 Hz inverter (pure sine wave) in 10 ms. It has a monitor panel that
shows me the condition of the battery.

Nothing is fool proof. But I hope that this more modern design can help me
avoid this sort of catastrophe in the future.

Just my 2 cents' worth.

Unfortunate that happened.

This is the UPS I bought at Dayton, it is 
the USC-30001 3KVA version. Not exactly 
ancient but they do mention Windows XP in 
the documentation... After sitting two 
years the batteries still are at 12.3V so 
they seem good.

In my case, the battery not only was overcharged, but the UPS died in such
a fashion that the 117 AC was interrupted several times and that killed my
computer, which it was supposed to protect.  I know the house current did
not flicker or drop during the time.  It was strictly the UPS.

I have replaced it with a modern unit that has a selectable "float voltage"
for several types of backup batteries.  In my case I selected a 100AH deep
cycle AGM construction unit.  If the house supply goes down, it switches to
a 60 Hz inverter (pure sine wave) in 10 ms. It has a monitor panel that
shows me the condition of the battery.

Nothing is fool proof. But I hope that this more modern design can help me
avoid this sort of catastrophe in the future.

Just my 2 cents' worth.

Virtually all UPS units include MOVs, so have all of the destructive
possibilities of MOV power strips. If you're going to use a UPS (and I do),
it should be plugged into a shunt-mode surge protector (SurgeX, Zero Surge,
or Brick wall).

I have an older Staco Energy UPS I've
never used, bought it at Dayton a couple
years back. Weighs a ton from the lead
acid batteries inside, need to put another
plug on it, it comes with a 30 amp 120V
plug and the house wiring doesn't support
that. I need to find an owners manual for
it as well, looks like there is a USB port
involved & it didn't come with a manual.
After getting the whole house protector I
should probably attach this to the stereo.

Or even sooner than that.  By dumb luck, I bought a couple of CyberPower 
units that do NOT have this serious design defect, AND which are also RF 
quiet. The model I bought is the CP1500PFCLCD. It has RFI filtering and 
meets FCC Part 15 Class B.


I'm guessing that I bought the first of these units 4-5 years ago, and 
it's been protecting a big "old iron" Dell tower ever since. Run time 
still seems quite good. I bought the second one a few years ago to keep 
low power 120V shack gear running through the occasional power drops we 
experience up here in the mountains. Both units are plugged into a 
SurgeX box.

Hi John,

I made a long post about this a day or two ago, and Eric has closed this 
thread. The short answer is yes, MUCH better.
