Watlow has expanded the Ez-zone ST controller range to include phase-angle power switching and increased load current for control of radiant quartz (tungsten) lamps for photovoltaic processing.

The Ez-zone ST now features single-phase solid-state relay output up from 40 to 75A and phase-angle power switching with soft start to prevent high in-rush currents, load failure or blown fuses.

It enables the production of PV cells where size and temperature uniformity are required to reliably produce a cell with high conversion yields.

This expanded offering improves thermal uniformity and temperature repeatability, and provides the functionality of multiple components and footprints collapsed into one.

The newer size is said to take up less overall surface area inside the panel than an equivalent solution assembled from discrete devices.

It provides a complete thermal system kit to reduce project and engineering design time, and is tested and validated for the specified ampacity.

The Ez-zone ST comes complete with a free internal communications bus (standard bus), which provides a single entry point for configuration and monitoring or location to access multiple controllers on the bus.

For those applications requiring a display or remote user interface (RUI), it has the option of adding a 1/16 DIN RUI as a stand-along device or combining the RUI with gateway functionality.

The gateway will access higher level field buses (Profibus, Ethernet/IP, Devicenet or Modbus) by converting standard bus to the field protocol once instead of outfitting each controller with an independent protocol card.
