  The Maxwell MS-1VD2238 Series is a highly cost-effective, high-accuracy single-phase isolated SCR power regulator designed for precise phase angle control. Featuring a versatile multi-input design, this advanced thyristor module simultaneously supports 0-5Vdc, 0-10Vdc, 4-20mA, and potentiometer control signals without requiring hardware modifications. Engineered with optical isolation between the input and output circuits, it ensures maximum operational safety and signal integrity. Available in a wide current range from 10A to 200A for both 220Vac and 380Vac loads, the MS-1VD2238 series incorporates a built-in soft start circuit and an internal buffer (snubber) to protect against voltage surges. Housed in a durable, fire-retardant enclosure with resin sealing, this panel-mounted regulator is the ideal solution for controlling resistive heating elements in demanding industrial environments.

The Maxwell SCR20CA Series is a highly integrated, single-phase AC power controller designed for advanced feedback control and precise voltage regulation. Built around a high-power thyristor (SCR) chip, this compact unit incorporates a digital phase-shift control circuit alongside highly accurate output voltage and current measurement systems. A standout feature of the SCR20CA is its multi-functionality: users can seamlessly switch between constant voltage, constant current, and constant power control modes directly via the digital panel or communication interface. Equipped with true RMS sampling and a fully isolated measurement system, it ensures safe and reliable operation. With built-in RS-485 Modbus RTU communication, pluggable control terminals, and comprehensive protection mechanisms, the SCR20CA is an ideal solution for modern, automated industrial heating and power control applications.

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
