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

● Potentiometer input SCR
● 500K, 1000K potentiometer
● 24~480Vac load
● From 10 amps up to 120 amps
● 500K for 220Vac
● 1000K for 480Vac

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.
