Model 3 AC Power Conditioner:
note: The Model 3 is world compatible with both single sided AC power,
Hot-Neutral-Ground, and balanced power, Hot-Ground Hot.
The Model 3 is available in two
we now offer the 32 amp IEC high current plug at the output for Boulder
Amps if desired by special order.
This version is for AC power of
100 to 130 volts and is convertible to 240 VAC just by switching the
This power can be single sided
such as the USA standard of Hot-Neutral-Ground, or balanced such as
All world standard systems are
accounted for in this design. The AC power can be single sided
such as USA or European Hot-Neutral-Ground, or USA 240 balanced such as
The conversion of any Model 3 from one voltage range to the other can be
accomplished in the field by simply exchanging the BIFROST module.
With the exchange of this one simple module, the Model 3 becomes
compliant with any grounded household AC power system in the world.
Production Model 3
And now, the future
The Model 3
based on the evolution of our sequoia sapling board and its variations,
continues to evolve with many new features.
The new model designation is
because it is not a version of the Model One. It is a new design
fundamentally, different and improved through its evolution in
multiple ways... yet is a power cord.
do not follow, We lead.
These are The Model 3's features:
No more fuses
they were slightly noisy and required replacement when blown.
- A Magnetic
Hydraulic Dual Circuit Breaker (Same as the Sequoia)
rated to the 20 Amp national standard. Its main feature
is it breaks and resets on both the hot and neutral rails and has a
quieter electrical operation.
- Certified Vishay Capacitors. These
capacitors are multinational certified and are designated for either
X or Y use depending on the place in the circuit.
- The Gas Tube spike and lightning
protection circuit combines with Metal Oxide Varistors of truly
modern design. It is out of the circuit so it is dead silent
in the circuit until protection from lightning needed, very fast
- Mosorb technology integrated into
the active circuit to give general surge protection to both
over-volt and surge current. Super protection, we invented the
arrangement into a new kind of replaceable package. ( Our name "BIFROST"
) Is a module. It is very quiet under normal operation and super
fast acting in the circuit when needed to clamp to ground. As
a sacrificial component it takes the potential damage from bad line
events which do happen in the real world. It is designed to be
completely replaceable in the field so shipping back to us is no
longer necessary when bad things happen in the world of AC power.
- Vishay precision bleed down
resistors - non inductive.
Cardas NEMA and 32 amp Powercon
& Cardas IEC plugs, custom modified design for use by JENA
Technologies. These are great, rhodium plated parts and these
replace the great parts we used. Better parts and are
very good looking.
- On the production versions...
Stainless end plates of heavy build and a distinctive appearance on
the production models. The laser cut .115 thick 11 GA SS T304
Stainless Steel is edge sanded for smoothing and then bead blasted
in house to give a finish that is easy to clean and will last many
years looking great. And the main housing parts are an anodized
aluminum extrusion we modify and line with Cascade Audio Engineering
- instead of the 9 wires of 16
gauge, we have been able to incorporate 11 wires of 16 gauge
wires into the weave of the cords, so it will handle the
heaviest loads of big amplifiers. Up to 20 amps before the breaker
- The assembly hardware, 6-32
button socket cap in 18-8 stainless steel is made by
Brighton-Best. (Why? There are a lot of cheap weak fasteners
on the market now... we refuse to use merely OK junk for anything.)
- Actual physical standard length
is about 8 plus ft long
The use of a dual Breaker and BIFROST is superior and
will give superior performance to the sound of this fabulous solution.
(BIFROST means: Bi-directional Integrated Field
Replaceable Over-voltage System Technology )
The BIFROST device itself is hand made by JENA
Labs directly in the United States.
The Sockets are a high grade Bakelite base with
high grade machined copper and gold plated receptacles.
With the need for high-performance
AC power conditioning, and with an eye toward reasonable costs, we
set out to create AC power-conditioning products that are
affordable yet give a range of AC power conditioning that will
satisfy almost any set of needs. All of these products are
award winning designs, built to last, with dependable and
predictable results that have made them famous.
We set the bar very high and with this series of AC power
Conditioners just set it higher with the new Model Two.
We started with a prototype of the basic circuit in an armatured
version like the AC power washing Machine of long ago.

has been equaled and beaten by the New Model 3 with higher grade
capacitors of higher values and a dual rail circuit breaker.
And a better design of greater capacity for the protection components as
well. The Model 3 is fantastic.
Originally we converted the design to be built onto a high
current capable Printed Circuit Card of our own design for use on a
single line as the Model one.
The PC Card has a built in buss bars that will handle over
20 amp loads with ease.
model One.3 a thermal
circuit breaker rated up to 20 amps on some models to match the house
line rating, It was much quieter than the 20 Amp fuse we use to
Various inductors are selected for frequency filtering over a broad
bandwidth of noise.
Cardas® quad eutectic solder is used always with all of our power
conditioners. Never any shortcuts to using the best of all
components and materials.
We hand select all of our parts and carefully choosing only the finest
and toughest for the purpose intended.
None of our conditioners are made by a machine, all are built by hand
by a NASA certified hand solder expert.
After we produced several hundred Model Ones... all are still out in
the field doing their work, none ever failed to do what it does... we
just decided to better our own product.
Why not, we learn, we grow. we design the best of the best. The
Model 3 is the standard by which others must compete with.

The Revolution in our power
conditioners is being advanced by the technical evolution of
all of our models.

products is the Model 3.
