INTRODUCTION
The PFC2 range of Capacitor switches provide
optimised switching and control of three phase
capacitive loads for Power Factor Correction,
suitable for a three phase supply using the two-leg
control technique. Signal control is by a DC signal.
They incorporate an automatic resetting
temperature trip fitted to the heatsink. They also
have an integral semiconductor power fuses.
The two models in this series include the 80kVAR
and the 100kVAR models, both of which are fan
cooled.
APPLICATIONS
The PFC2 controllers are suitable for 3-wire, 3-phase floating-star or closed-delta configured capacitive loads for Power Factor
Correction and can be used in capacitor banks with or without chokes fitted.
These power control stacks are designed to dramatically reduce the inrush current normally found with contactor based systems,
They also allow for repetitive and rapid switching as there are no mechanical contacts to arc, and feature a controlled switch off
to minimise flicker and eliminate RFI problems.
These power switches could be used in places where rapid changes in Power Factor could be seen such as welding plants, lifts,
cranes and wind powered plants.
