Should you use contactors, solid-state relays, or SCR power controllers? We'll review various power control options available on the market, considering key advantages, typical network communications capability, and cost-saving features.
We'll discuss interface software tools and features to manage set up and monitor operation-and can even allow you to tap into data for greater process insights and control. We'll also look at operating modes, including zero-cross (full-cycle) mode and phase-angle mode, as well as SCR power controller output regulation methods for voltage, current, and power output regulation. Regardless of your application or specific process conditions, there are measures you can take to more accurately and efficiently control your industrial thermal process and lower your cost of operation and total cost of ownership.
- Understand the primary parts of a typical temperature control loop and the power control loop for electric heating
- Understand the differences in contactors, solid-state relays, and silicon-controlled rectifiers (SCRs) that control power from the grid to the heater
- Consider specification features in SCR power controllers, such as power efficiency, accuracy, reliability, network connectivity, and ease of integration
- Learn about advanced operation modes that improve efficiency
