Power
Controller for Custom
Tailoring to the Application
The QPAC SERIES from Watlow
®
is a modular Silicon
Controlled Rectifier (SCR) power controller with plug-in
features for flexibility. Bases are rated from 150 to 1000
amperes in one-phase, three-phase, two leg and three-phase,
three leg.
A variety of transformers are available (NOT INCLUDED) from 120 to 575VAC along
with 50/60Hz operation enable the QPAC to operate in
applications anywhere. Plug-in control cards set the
QPAC’s SCR firing modes; solid state contactor, burst
firing (zero cross) or phase-angle models are available with
a wide variety of options. This power controller includes 200KA
short circuit current rating (SCCR) and high speed fuses to
minimize damage in the event of a short circuit.
