Recently, I posted a question about where to begin looking for proper
line/power conditioning and surge suppression. A couple of you asked
that I post what I learned and what I eventually purchased. Well,
with one answer comes another question. I sought the advice of a
couple of electrical engineers that I know. One is a power system
designer and the other is a chip designer. Both were somewhat
skeptical with line/power conditioning. Both were adamant about the
need for surge suppression. It seems that line/power conditioning is
a catch all term. But both agreed that a line conditioner that
provided a steady voltage, and would filter out some of the line noise
can only be a good thing... but cost needed to be considered. For
surge suppression, you need at least a rating of greater than 1,500
Joules. Preferably, greater than 2,000 Joules. Also, some indication
as to the condition of the surge suppressor would be important...
indicating that an event had occurred.
The "go-to" manufacturer when it comes to these two items appears to
be TrippLite.
I purchased the TrippLite LS606M Line Conditioner. I didn't have a
need for a UPS, so no batteries for this unit. (note that the surge
suppression on my unit is below 1,000 Joules)
To provide more surge suppression, I added a TrippLite ISOBAR6Ultra
surge suppressor. My only question is where to place the ISOBAR
surge suppressor, upstream or downstream of the Line Conditioner. My
uneducated preference would be to place it upstream of the line
conditioner. But, the rule of thumb from the electrical engineering
community is to place it as close to the device to be protected as
possible... I think that we are now splitting hairs.
Now for pricing... I found that www.provantage.com had the best shelf
price and the best inventory. But, you will have to pay for
shipping. www.amazon.com was a bit more expensive, but provided the
option for free shipping. The price then nets out the same between
the two.. but provantage had the best selection. The TrippLite
website provides a nice list of prices from various distributors.
ISOBA6Ultra = $42.83
LS606M Line Conditioner = $69.17
I also purchased the ISOBAR6DBS for each of our TV's. $49.01
Sometimes, one pays for protection to get the "feeling" that they are
protected. I think that TrippLite has a product that is actually
providing real protection.
