ExactPower SP15A
The ExactPower SP15A has been designed to isolate and reduce unwanted noise from your Audio Video equipment for improved picture and sound quality.
The ExactPower SP15A provides 15 Amps of balanced current. The voltage on the output receptacles is symmetrical around the earth ground. The "Line" and "Neutral" are of equal voltage and opposite polarity or phase. The voltage is 60Vac on each side of ground, so that the total output is 120Vac, which is the US standard.
The critical part of the SP15A is the design of the transformer. The type of transformer that is used is a toroidal transformer. This is the only type that can give the best results. The transformer must provide isolation, noise reduction, and inaudible acoustic noise. The transformer is wound with the bifilar method. This method reduces the noise that is present on both incoming "Line" and "Neutral". This noise is called "Common Mode Noise". An electrostatic shield is placed between the primary (input) side and the secondary (output) side of the transformer. This reduces noise by using a copper strip that is connected to the earth ground. High frequency noise, that is on the primary, is shunted to the shield and then to ground, so it never reaches your components. Precision winding provides for a consistent transformer. We utilize only the best materials.
We have two units to choose from, a unit without the EMI and RFI filters to be used with the EP15A, and a unit with the filters to be used as a stand alone product. Although the unit with filters can be used with the EP15A, the filters would be redundant since the EP15A incorporates these filters. The SP15A also incorporates filters for digital equipment on four of the receptacles. These filters block any digital noise that may be present on the power line of a digital product from contaminating other products powered by the SP15A.

Features
Oversized Custom Toroidal Transformer: Meticulously crafted transformer with electrostatic shield. Utilizing computer controlled winding machines to precisely place each winding for optimum noise rejection.
High Current High Frequency Filters: Filters to remove the digital noise from connected digital equipment.
Eight "full contact" AC receptacles: These receptacles are the same ones that are used in the EP15A. We use only the best Hubble receptacles.
EMI and RFI filtering: Even the widest bandwidth electronics cannot eliminate all the EMI and RFI problems, therefore we have incorporated custom designed EMI and RFI filtering. (Optional)
