SERIES 700A - SINGLE PHASE POWER LINE CONDITIONERS
This specification covers the electrical characteristics of the Power Processor, which provides clean regulated power for electric/electronic equipment and peripherals.
The Power Processor, Power Line Conditioner consists of an all copper, multiple tapped, triple shield isolation transformer. The low output impedance of the transformer in conjunction with the electrostatic shields assures precision computer grade performance with excellent noise and transient attenuation. Independently controlled inverse parallel electronic switches for each of the 7 taps per phase provides tight regulation over a wide input range. Linear devices are used for line synchronization to prevent phase shift errors normally associated with simple CT zero current crossing acquisition. The microprocessor control accurately selects the correct tap to maintain the output no greater than 3% of nominal, correcting for voltage disturbances within one cycle. Digital processing technique provides fast and accurate regulation without output voltage over or undershoots.

FCC Article 15, Section J, Class A
The system shall be listed to U/L standards UL1012
The system shall comply to: FCC Article 15, Section J, Class A and
ANSI C62.14 (electromagnetic compatibility)
3.0 DYNAMIC ELECTRICAL CHARACTERISTICS
