EZ-Zone ST line includes single-phase solid-state relay output up from 40 to 75 A and phase-angle power switching with soft-start to prevent high in-rush currents, load failure or blown fuses. The controller with phase-angle control and higher current capacity is suited for the production of PV cells where size and temperature uniformity are required to reliably produce a cell with high conversion yields. The controller effectively manages the radiant quartz (tungsten) lamps commonly used in the manufacture of PV cells to deliver specific thermal profiles rapidly.
