Boostek switches the start capacitor
during momentary overloads and multiple motor starts during equipment
operation, providing a "Boost" when needed.
Zero Crossing reduces heat buildup in the capacitors, this increases
capacitor life due to ho high current flow in the capactor banks.
Boostek uses the start capacitor for more than initial start.
Zero Crossing switches active (AC) fixed (run) capacitors and passive
(DC) start capacitors without arcing of your contactor, this technology
reduces electrical stress on your equipment making the Booster superior
to a standard phase converter.
Boostek also makes controllers that have phase balancing (symetry)
pulse width modulatio (Controller) digital binary weighted T controller
