The Story
The original Torus Power models in the RM series remain unparalleled for performance, protection, and value, with models from 15 Amp to 100 Amp.
A popular model in the RM series is the RM 20, which has been consistently top-rated by leading audiophile magazines. Torus Powers power isolation units (PIUS) combine search suppression with massive toroidal transformers to provide AC power conditioning and protection from voltage surges.
The RM 20 uses a single 2400 VA toroidal transformer to supply 120V at 20A to the 10 AC outlets on its rear panel. It has a 20 a circuit breaker for its on-off switch and uses a 14 AWG detachable AC cord rated at 15 amp/125V. “The PIU greatly enhances subtle details of tone, timber, and imaging when dynamics were extreme, or the volume was loud”, and is a recommended component of Stereophile magazine.
Torus Power RM, AVR, and AVR2 series models use extra-heavy-duty medical-grade outlets custom-manufactured by Hubbell. These outlets provide greater contact force, reduced heat buildup, and redundant grounding and are vastly superior to commercial-grade outlets. Torus Power 15 Amp & 20 Amp Outlets are available for purchase.
Toroidal Isolation
Torus Power transformers electrically isolate connected equipment from the incoming power. Torus Power Toroidal Isolation transformers feature triple shielding for ultimate noise attenuation and isolation from the increasingly noisy and polluted power lines.
Narrow Bandwidth Technology
Torus Power Toroidal Isolation transformers restore incoming power to its clean original state using proprietary NBT transformer technology.
Torus Power’s design carefully balances the inherent inductance, capacitance, and resistance characteristics of the toroidal transformer, enabling the transformer to act as a very effective low-pass filter.
Series Mode Surge Suppression
Torus Power protects connected equipment through innovative series mode surge suppression that also pays attention to keeping the power clean. 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.
Torus Power’s design absorbs surges more than 2V above peak line voltage, so the ground is not affected.
Torus Power surge suppression meets IEEE endurance standards of 6000 Volts, 3000 Amps, with 1000 repeats. Torus Power further innovates by using the Toroidal Isolation transformer to replace the series inductor typically used by other brands. This ensures extremely low stray magnetic fields within the chassis.
High Instantaneous Current Capability
Torus Power isolation transformer provides a very low source impedance to connected equipment, enabling high current delivery on an instantaneous basis, allowing amplifiers to deliver maximum performance and dynamics.
This is the foundation enabling high-resolution audio systems to achieve a wide dynamic range with clean, distortion-free musical peaks even at high volume levels.
High Res Power
Torus Power isolation transformers keep the noise floor as low as possible while still providing ample, unrestricted current on demand. This is the foundation enabling high‐resolution audio systems to achieve a wide dynamic range
