The PCI (phase-angle, cosine intercept) power controller series provides full wave output
Robiconase-angle, cosine intercept) power controller series provides full wave output with full wave, phase-angle fired control. Typically, phase-angle fired silicon controlled rectifiers (SCRs) regulate transformer coupled loads or loads with transient characteristics. But other control circuits can be sensitive to line fluctuations, and fail due to line voltage noise. To correct this problem, Robicon has added cosine intercept linear phase control to efficiently diminish the effect of noise on the unit. On one compact printed wiring board, the all-semiconductor gate trigger unit (GTU) combines the noise immunity of cosine intercept linear phase control with hard drive gate output circuits and a voltage regulator preamplifier. The GTU drives an inverse parallel-connected pair of SCRs for each phase controlled. The PCI Series can be operated into resistive or inductive loads driven directly or through an interposing transformer. Units are available with ratings of 25 to 1200 A and at 120 to 600 VAC.
