2.4General Operation Notes

The Power-Sure™ 700 Power Conditioners provides the triple function of isolation, noise attenuation and voltage regulation. The first two functions are provided by the power transformer, where as the third function of voltage regula- tion is achieved through solid state thyristors (SCRs) connected to taps on the power transformer. A micro-processor monitors and controls the overall function of regulating the system.

The power transformer is manufactured with a unique method of shielding which produces very low capacitive coupling between the primary and secondary. This low coupling provides excellent attenuation of the common-mode noise. In addition, special care is taken in the design of the transformer to attenuate transverse-mode noise above 1000 Hz. The power transformer has taps to which solid state switches (SCRs) are connected.

The voltage regulator incorporated in the Power-Sure™ 700 Power Conditioners is microprocessor controlled to achieve optimum correction time of input voltage sags and surges. The response time is typically one (1/2) cycle for 100% correction, therefore, a very smooth switch takes place undetected by computer equipment.
