Description
Torus Power PIUs (Power Isolation Units) combine the best
surge suppression with unique toroidal transformer
technologies from PLITRON to provide the ultimate in AC
power conditioning and protection for sensitive audio and
video equipment applications.
PIUs use ZeroSurgeâ patented series-mode surge removal
filters to absorb dangerous voltage surges and safely dissipate
them without using failure-prone MOVs (metal oxide
varistors). Also, unlike MOV-based protection, voltage surges
are not shunted to ground.
Units are available in either dual 120V (balanced) input or, in
lower-power units, single 120V input.
Isolation is combined with proven proprietary technologies
from PLITRON in the over-sized toroidal transformer. NBT
works as
a
low pass filter using the controlled leakage
Balanced input power from two standard 120V phases
provides high input power and noise cancellation. Using
balanced input power provides the benefits of symmetrical
power without the requirement to use GFCI (ground-fault
circuit interruption) outlets. GFCIs are prone to nuisance-
trips. The toroidal isolation transformer steps-down the 240V
input to 120V to power equipment. (Where 240V balanced
input is unavailable, units may be configured for 208V
operation.)
inductance and capacitances within the transformer to cancel
common mode and differential mode noise. LoNo technology
has been used for years by high-end audio companies who
demand silent transformers. Imin technology reduces inrush
currents. UST provides additional common mode filtering
using a highly efficient faraday screen.
Low-impedance output with balanced high-power primary
input provides the most unconstrained, yet protected, energy
source available to your equipment.
Shipping Carton & Packing Material
Placement & Ventilation
Please keep the original shipping box and all packing material.
This will ensure the PIU is protected in future transport.
Torus Power PIUs are extremely efficient devices, however,
they are also very high-power devices, and must be
adequately cooled.
In the unlikely event you have a problem and must return it for
service you must use the proper packing material.
PIUs have ventilation slots on the base, side panels and the
cover. Maintain at least 1” distance from each of these
surfaces to anything else. Should your installation conditions
be constricted, additional forced air-cooling may be
necessary.
Ship the PIU only in the original packing material, as the unit is
not insurable by carriers otherwise.
Do not install the PIU directly above heat-generating
equipment.
Maintain at least 6” behind the PIU for adequate wiring space.

Circuit Protection
The front panel output power
switches are also circuit breakers.
The switches correspond to groups
of receptacles on the rear panel.
When the power is on, the Switch is
illuminated. When the breaker trips,
the switch returns to its “off”
position.
Thermal Protection
Torus PIUs will shut-down if internal
unit temperature reaches excessive
levels.
Power-Sharing Outputs
The front panel Output Power Switches are numbered to
correspond with outlets on the rear panel. Each
Switch/Breaker controls and protects
a
bank of outlets.
single winding
However, all three outlet banks share
a
(output) on the isolation transformer. This “Power-Sharing”
allows huge excursions of current, up to and beyond the full
power of the unit, to be available at any individual outlet, for
instantaneous bursts of power.

Warning
Installation by qualified
electrician required.
A dedicated circuit is required for
these units. Wall outlets for 240VAC
are rated at 250V and will require
special installation. Dedicated
outlets, or any household or facility
wiring should be installed by
licenced electrician to local codes.
a
Wall Receptacle
Torus PIUs are high-power products.
The outlets they are plugged into
should be sufficient to provide the
current to operate them without
tripping circuit breakers within your
junction panel.

Warranty
Torus Power products are warranted to be free from
manufacturing defects for a minimum of five years from the
original date of sale. This includes parts, labour and return
shipping to the first registered owner and all subsequent
registered owners. Warranty coverage is extended to
applicable products registered or having proof-of-purchase
(sales invoice, etc.).
In the event of a defect or malfunction, Torus Power will
remedy the problem by repair or replacement, as we deem
necessary, to restore the product to full performance.
This warranty is considered void if the defect, malfunction or
failure of the product or any component part was caused by
damage (not resulting from a defect or malfunction) or abuse
while in the possession of the customer. Failure to fully comply
with Torus Power operating instructions, voids the warranty.
