Industrial Applications

1. Industrial Furnace Temperature Control

Utilized within a PID temperature control loop for an industrial electric furnace. The SSR's 12-24VDC input is controlled by a PLC's analog output module, precisely modulating power to high-wattage heating elements.

Problem Solved

Mechanical contactors used for controlling high-current heating elements wear out quickly due to frequent arcing and mechanical fatigue. The G3PE-245B's solid-state design offers no-wear, high-frequency switching, leading to significantly longer operational life and more precise temperature regulation.

2. Thermoforming Machine Platen Control

Controls the multiple resistive heating elements embedded in the platens of a thermoforming machine. The SSR's high 45A current rating allows it to handle the significant power draw of the platens, while the zero-cross function minimizes electromagnetic interference that could affect sensitive machine controllers.

Problem Solved

The rapid and repeated heating cycles required in thermoforming cause premature failure in electromechanical relays. The G3PE-245B provides a durable, silent, and fast-switching solution that can withstand millions of cycles, ensuring consistent platen temperature and reducing machine downtime.

3. Commercial Bakery Proofer and Oven Power Regulation

Manages the power supplied to heating and humidity elements inside a commercial bakery proofer or convection oven. The 12-24VDC control signal allows for direct interface with modern digital bakery control systems for precise environmental management.

Problem Solved

Maintaining exact temperature and humidity is critical in baking. Traditional relays can cause temperature overshoots and undershoots due to slower switching speeds. The G3PE-245B's fast and precise switching capability, driven by a low-voltage DC signal, ensures stable temperatures, leading to consistent product quality and reduced energy waste.
