I wouldn't rely on a power conditioner/regulator to be your first line of defense when it comes to surges. Get a decent surge protector installed at your main power panel. There's a few threads here on AA talking about doing just that. It's cheap insurance and in my opinion a must have.

The Ditek DTK-120/240HD2 and Eaton CHSPT2ULTRA are both good choices.

Everything plugged into an Equi=Tech 5RQ (5kVA, 240 volt/30 amp) balanced power unit which outputs 2 x 20 amp 120 volt circuits and 1 x 10 amp 120 volt circuit.

My almost 9 year old MC2301's feed from their own dedicated 20 amp breakers. They love being fed direct AC (and to the point)

Best sir,

My 601s are plugged into a Shunyata Denali conditioner which is plugged into a 20 amp dedicated circuit.

With Isotek power conditioners I have found that all my gear, amp include sounds even better plugged into the conditioners. For the amp I utilize and Isotek EVO3 TITAN.

Hmmmm, this doesn't sound quite right. How can you get two 120V 20A circuits + one 120V 10A circuit from one 240V 30A circuit? They can't possibly be truly independent circuits, correct?

How do you get multiple 120 volt circuits from your single 240 panel ?

The Equi=Tech ties into the 240 panel and then uses a balanced power isolation transformer to generate the individual 120 volt circuits from the single 240 feed.

amps * volts = watts

240 volts * 30 amps = 7,200 watts (maximum input into the isolation transformer)

120 volts * 20 amps * 2 = 4,800 watts (maximum outputs 1 & 2)
120 volts * 10 amps = 1,200 watts (maximum output 3)

(4,800 + 1,200 watts) = 6,000 watts < 7,200 watts (Note: 3 * 120 volts * 20 amps = 7,200 watts, but Equi=Tech probably designed in a safety margin)

I would assume the 3 circuits derived from the 240 volt / 30 amp feed comes from the multiple secondary windings in the specific isolation transformer being used.

See Equi=Tech's spec page for more details.

http://www.equitech.com/products/rack/modelqpro.html

See also: Multiple winding transformers:

http://www.electronics-tutorials.ws/...nsformers.html

I would assume the transformer being used would be something similar to the one pictured below, but with 1 primary input winding and 3 secondary output windings (as well as balanced power +/- 60 volts/120 volt differential on the secondary wirings).


Someone that knows more about transformers (especially 240 volt transformers) can correct me if my assumptions are incorrect.

Also: There is a 240volt/30amp breaker in the service panel and separate 120 volt 10 and 20 amp breakers in the Equi=Tech. From the calculations above, the breakers in the Equi=Tech would appear to trip before the breaker in the service panel.

Here is what a balanced output transformer would look like (the 240 volt versions would also incorporate 2:1 step-down windings):

Cleeds, I found this sheet about another vendor's combination step-down/isolation transformer. It confirms my assumptions above. It takes a single 240 volt input and outputs 5 * 20 amp 120 volt balanced power circuits (+/- 60 volts, 120 volt differential). It is twice the size of my Equi=Tech unit.




Here is a review of one of Equi=Tech's service panel units similar in size to the above competitor.

http://www.6moons.com/audioreviews/equitech/1.html

FWIW: Equi=Tech was instrumental in amending the National Electric Code (NEC) to include "Technical Power" in 1996 and 1999. That seems to be a substantial contribution to clean power technology.

My amp (dual mono) has two Shunyata Sigma HC power cords direct to the wall. The Sigmas perform a conditioning function by themselves while avoiding any current choking that sometimes occurs with line conditioner components.

Default Do you connect your amp to your power conditioner?

My 601's are plugged into a P10 Power Plant which in turn is plugged into a Furutech GTX-D Rhodium receptacle on a 20-amp dedicated circuit.
