Torus Power A120-HFB-A5AB manual Description

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.

Units are available in either dual 120V (balanced) input or, in lower-power units, single 120V input.

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.)

PIUs use ZeroSurge￿ 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.

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 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.

In the unlikely event you have a problem and must return it for service you must use the proper packing material.

Ship the PIU only in the original packing material, as the unit is not insurable by carriers otherwise.

Torus Power PIUs are extremely efficient devices, however, they are also very high-power devices, and must be adequately cooled.

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.

Do not install the PIU directly above heat-generating equipment.

Maintain at least 6” behind the PIU for adequate wiring space.
