- Torus isolates equipment totally rom the power grid  using toroidal transformers, and not filter circuits

- Torus protects connected equipment and dramatically improves performance

- More dynamic audio performance

- Spectacular colors for video 

- Products for all systems from 2.5Amp to 100Amp

ISOLATE.  Torus Power Isolation Units (PIUs) totally isolate your audio/video system from the harsh AC power line realities that can degrade every aspect of audio and video performance.    Most competitive products in the category are simple filters and do not provide isolation between the outside power grid and the inside power source.  

The Torus PIU’s deliver true isolation (using toroidal transformers), designed to provide low source impedance, and large enough instantaneous current for today’s most sophisticated and powerful equipment, including high power audio amplifiers. 

PROTECT. The ever-present risk of severe power line spikes caused by everything from machinery and common household appliances to lightning storms is a constant threat to your system. Torus provides state-of-art protection and series-mode surge without the use of failure-prone MOVs (metal oxide varistors).  

INSPIRE.  Torus Power restores  resolution and dimensionality to audio and video systems.   Read the reviews and user comments to understand the depth of improvement. 


TORUS AVR - Automatic Voltage Regulation Series
Torus AVR series uses a micro-processor to monitor and control incoming voltages, and keep the output voltage constant to connected equipment within the range of 120VAC +/-5VAC.  The AVR series provides all the other benefits and features of Torus Power including isolation, surge suppression, noise reduction.   AVR series is ideal for areas where voltage fluctuations, brownouts are a concern.
 

• Very low source impedance and high current for the power amplifier
• Power surge protection using Series Mode Surge Suppression rather than MOV's
• Total isolation from outside power grid
• High Power Capability
• Low Noise
• Cleaner Power
  See below for more technical description of these benefits.

                What's inside?
Transformer used in Torus units, pictured below, features triple-screens for ultimate noise rejection. Also note metal mounting band that "suspends" the transformer inside the cabinet, further reducing mechanical noise

Toroidal transformers are typically half the size and weight of conventional transformers.
But, Torus uses transformers which are twice the mass of standard toroids to provide extremely open high power. Torus Power transformers  have sufficient reserve power capability to provide all the current needed for high power systems.

Benefit # 6:
Cleaner Power:

Torus power products provide isolation through its finest designed toroidal transformer between the outside power grid and the devices being protected. Such isolation helps to reject external noise sources such as motors, lights, and dimmers commonly  found in the home environment. Torus power products provide noise filtering at a range from approximately 2000Hz to over 1MHz – other regular transformer based products do not start operating until nearly 10,000 Hz.
 

Torus PIUs use series mode surge suppression which absorbs surges more than two volts above peak line voltages. Torus surge suppression meets IEEE endurance standards of 6000V, 3000A with 1000 repeats. Torus Technology allows for the replacement of a series inductor with the Torus isolation transformer. The transformer has lower stray fields and higher current capabilities than the typical series inductor.

Most surge-suppression circuits are shunt-mode. Excessive voltage surges are "shunted" to ground, which raises ground voltage and may contaminate audio and video signals. Shunt-mode surge protectors usually use MOVs (metal oxide varistors) which are sacrificial components, and usually become ineffective over time.
