Announcement: Eurotherm® Joins Watlow® - Read Press Release

DISCONTINUED: QPAC

Recommended Replacement: ASPYRE® DT SCR Power Controllers
The QPAC modular controller from Watlow was 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 and three-phase, two leg configurations. A variety of transformers from 120 to 480VAC, along with 50/60Hz operation, enable the QPAC modular controller 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 and are available with a wide variety of options. High speed fuses are included to protect the SCR modular controller from short circuit currents. 200KA short circuit current rating (SCCR) prevents arc flash.
