This is a single phase SCR power regulators and temperature controllers 2 in 1 units, in a typical heating system, you would need a temperature controller and a SCR power regulators, and they are two separate devices, we go further and build this two devices in one package, this saves a lot of efforts for panel builders when it comes down to wiring, and RS-485 modbus is a standard feature, controller can be integrated to systems with HMI or PLC etc. the load can be directed wired to this thyristor power regulators, and it works with all kinds of inputs, Thermocuple, RTD, analog signal

The SCR-6 Series is a high-performance, three-phase intelligent digital power regulator designed for precise control of resistive loads in industrial heating applications. Featuring a compact design with an integrated heatsink and cooling fans, the SCR-6 offers a reliable and cost-effective solution for thermal process automation.

The Maxwell SCR-7 Series is an advanced, three-phase intelligent digital power regulator designed for precise and reliable control of resistive heating loads in industrial applications. Engineered with a fully integrated design, it combines the SCR module, high-efficiency heatsink, and cooling fans into a single, compact unit. The SCR-7 series features a comprehensive digital display for real-time monitoring of output ratio, temperature alarms, and phase status. With support for multiple analog input signals (including 4-20mA, 0-10VDC, and 0-5VDC) and optional RS-485 Modbus RTU communication, it seamlessly integrates into modern PLC and automated control systems. Built-in protective features such as soft start, auto phase detection, and over-temperature alarms ensure maximum safety and longevity for both the regulator and the connected load.
