Isolate and reduce unwanted noise Improved picture and sound quality Proprietary toroidal transformer Low output impedance Available with EMI and RFI filtering CE and UL approved Available in international versions

Critical to the SP15A is the design and manufacturing process of the transformer. At ExactPower we design and manufacture all our own transformers in-house in the USA, and we utilize only the best materials and highest-quality workmanship. This ensures that transformers meet our stringent specifications and perform to their full potential.

Reducing Common Mode and Digital Noise
Our Toroidal Transformers are wound with a proprietary symmetrical layering method. This method reduces the "Common Mode Noise" that is present on both incoming "Line" and "Neutral." 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 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.

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.

Optional EMI and RFI Filters
There are two units to choose from: one without the EMI and RFI filters to be used in conjunction with the EP15A, and one with the filters to be used as a stand-alone product. Although the unit with filters can be used with the EP15A, the filters are redundant since the EP15A incorporates these filters.
