Balanced Isolation Power Conditioner Series

High Quality Toroidal Isolation Power Transformer

Surge Protection: BP-Series power conditioner 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. KECES design absorbs surges more than 2V above peak line voltage, so ground is not affected. KECES 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.

Input Voltage Detection:Under Voltage Protection (UVP) Over Voltage Protection (OVP).

Isolation Ground:Since balanced power these voltages are of opposite polarity though, and given that most interference in a typical AC line is common between the two lines, the noise in the lines is eliminated when the two lines are added together. This is effectively known as Common Mode Rejection (CMR).
