I have a system in a remote mountain location that includes:
-faroudja dvd
-theta laser discr-
-motorized lift
-VCR
-DirectTV
-Blulu ray Denon
-crestron
-key digital image switcher
-Mark Levinson, etc.

The voltage surges to 134 volts on a frequent basis.
I wanted to buy the Accuphase PS-1210 or PS-510 voltage regulators, but they are built such that they shut off after a 10% surge over 117volts, or about 129 volts, which would constantly power off the equipment.

Any recommendations on a high quality unit that would handle surges to 134 voilts??

I agree with kal Kal Rubinson, you can also look at many other type of commercial/pro power products from tripp lite and the likes. Do not look for audiophile grade products and stay away from richard gray.

The PS Audio Premier shuts off at 140 volts on models with the most current upgrades. I have the same problem in my location. My voltage would surge to about 130 volts at certain times of day shutting off everything. PS Audio sent me a current Premier and it stopped doing that. Now on those occasions when the voltage gets around 130, I can keep on using my theater. The Premier keeps the voltage at 120 so none of my equipment "sees" the high voltage. However, I have found that I must use a small ultra quite PC fan on the Premier to keep the internal fans from turning on in this situation. I don't know how the Premier reduces voltage but it would appear that the process increases the temperature of the unit. At any rate, with the small fan, everything works perfectly without the much louder and very audible internal fan being turned on.

Never become so involved with something that it blinds you.

The spec sheet and user manual of the PS-510 doesn't claim to regulate beyond 120V, +/- 10% which is standard power quality deviation. Its beautiful looking.

You can get high quality regulation up to 150V with a APC LE 1200 for $45. What makes regulators more expensive isn't the regulation, a technology that is 30 years old, but the watts needed per regulator, so it has to be bigger and heftier.

... The voltage surges to 134 volts on a frequent basis...

Too bad that you can't "bottle" some of that surge energy for those big bass peaks! What is going on with the power up in your rarifed altitude?

Anyway, to your question. CVTs (Constant Voltage Transformers) will handle surges like these without shutting down. They are actually the most "bullet proof" type of surge protection that you can employ. Sorenson and other vendors make these in a wide variety of sizes and power ratings. Beware that they can get big and heavy and also can emit audible hum, so careful placement is often indicated. I would recommend reading the sorenson white papers on the subject.

Be careful most of those companies products are not certified and not tested.

I think I will try one of the following:
1. Tripplite Model #: HTRL15UPS
2. APC S-15

Does anyone have any recommendations between these two? I am most concerned about audible noise emited from these, or are they silent?
Thanks.

For some reason money spent in this category has not equaled quality received for me. We have bought Furman in the past, as well as others $5K+ and they did not get the job done.

To me, part of the issue is the companies that market to high end audio guys vs companies that sell to industrial applications such as hospitals. As stated above, companies like Richard Gray are not UL or ULC approved, and technically, if their equipment causes a house fire (extreme example I know), your insurance company can bail on any payout since they have no UL approval.

Similarly, I see too many ads hyping up what their product does vs showing actual performance printouts and graphs.

Furman is sort of inbetween, they started out as a Pro PA company supplier, making surge protectors for effects racks, and moved into pro audio stuff. I have worked on some of their pieces, and it was fairly well built.

I'd look towards Tripplite, that has always been more of an industrial company rather than glossy finish boxes with blue LEDs on it.

I'm glad no one mentioned Monster. I've taken apart and repaired a few of their pieces in the last 2 years, and to me they are a joke. BB sure sells a few of them though, which in itself speaks volumes as to the customer they are marketing to.

I have an s-15 in each of my houses. In one, it is in a rack about 15 feet away. In the other, it is in a rack about 5-6 feet from me. Neither is audible except when a relay clicks during an operation.

Curt, I've never seen a Policy Clause which allows an Insurance Co. to deny a claim because of the use of a non UL device in a home. Such a clause may exist, but I doubt it. I think the State Insurance Commissioner would come down pretty heavy on any company which tried to deny a claim on a non-existent exclusion. Regards, Norm

Kal,
Thank you for the information. My main concern was noise.
Does the S15 have a fan that can introduce any noise? This will be placed near the listener, in a very quiet room. Your advice on this would be greeatly appreciated.
Thanks

Most of the APC UPS units that I have run across utilize a fan that runs while operating from battery - very noticeable as well as Sonalert beeping. Other than that, they are pretty quiet. Most of these units are designed to trip on surge voltages that you are seeing, so you might be annoyed at the sound of the UPS triggering.

Well that's interesting, it's something that I heard in passing. I used to use it as a sales pitch to get people to buy ULC devices rather than Taiwanese made disco lighting effects back when I was doing nightclub installs in the late 80s, and the local distributor was getting all effects ULC (OK, called CSA) approved before they sold them... at a surcharge of course.

I know that Canada does indeed have tougher laws than the US when it comes to things like grounding and ULC approval, so maybe it doesn't apply in the US, but I thought such a clause did indeed exist, if only in Canada maybe?

FYI, I just checked my Ikea desk lamp, and it is ULC approved.

They very well could be from pre-digital times; as far as smoother light, I haven't the faintest idea what you are talking about. They all use incandescent bulbs.
