Three-Phase Intelligent SCR Power Regulator The Maxwell TC-200S Series is an industrial-grade, three-phase intelligent SCR (Silicon Controlled Rectifier) power regulator designed for precise, stepless control of resistive heating loads in demanding industrial environments. Manufactured by Maxwell Automation Technology Co., Ltd. under the PIDMaxWell brand, the TC-200S combines a fully digital control architecture with an integrated dual-row LED display, multi-function indicator LEDs, and a front-panel keypad, enabling operators to monitor process parameters and adjust output settings directly without external programming tools. The regulator accepts a wide range of analogue control input signals — including 4–20 mA, 0–20 mA, 0–5 VDC, 0–10 VDC, 1–5 VDC, and 2–10 VDC — and features automatic phase detection, making it straightforward to integrate into new or existing control systems. An integrated soft-start (ramp) function eliminates inrush current surges at power-on, protecting both the SCR modules and the connected heating elements from thermal shock. When the heat-sink temperature exceeds the user-defined alarm threshold (AL1), the unit automatically reduces output power to a configurable safe level (EOP), maintaining process continuity while safeguarding the internal SCR modules from thermal damage. An optional RS-485 communication interface with Modbus-RTU protocol enables seamless integration into SCADA systems, PLCs, DCS, and industrial IoT networks. The TC-200S supports auto/manual bumpless transfer, run/stop control, and configurable minimum and maximum output limits, providing the flexibility required for a wide range of industrial heating and process control applications. Rated current options of 100 A, 125 A, 150 A, 175 A, 200 A, and 225 A cover load capacities from 48 kW to 190 kW (three-phase), making the TC-200S suitable for small laboratory ovens through to large industrial electric furnaces.

SCR-51 series is a compact design cost effective three phase SCR power regulator, works perfectly for resistive load. With built-in heatsink and cooling fans.  Makes it very easy to use. Load option starts from 40 amps all the way up to 100 amps,  with a built-in overheat thermo protection to make your system always protected. Clear digital display for temperature and input/output indication.

The PT100-8 is a probe-type Platinum Resistance Thermometer (PT100 RTD) distinguished by its adjustable insertion depth — a key feature that sets it apart from fixed-length sensors. A stainless steel compression fitting is integrated into the assembly, forming a liquid-tight or pressure-tight seal against the process wall while allowing the operator to slide and lock the probe at any desired insertion depth before or after installation. This eliminates the need to specify a fixed immersion length at the time of ordering and greatly simplifies retrofitting into existing equipment. The probe is constructed from 304 stainless steel and is available in diameters of 4 mm, 5 mm, and 6 mm. The lead cable is shielded with a metal braid and covered with PTFE insulation, delivering low noise, high mechanical strength, and excellent resistance to elevated temperatures. The PT100-8 is compatible with a wide range of process fittings — including NPT, BSP, and metric threads — and is available in a waterproof configuration, making it suitable for measuring the temperature of both air and liquids across diverse industrial environments.

The PT100-19 is a probe-type PT100 Platinum Resistance Thermometer equipped with an M12 4-pin connector, combining the measurement accuracy of a Class A PT100 element with the convenience and reliability of the industry-standard M12 circular connector interface. The M12 4-pin connector enables rapid, tool-free mating and de-mating in the field, eliminates the need for field wiring, and provides a secure, vibration-resistant connection that is well suited to machine-building, automation, and process control applications. The sensor is constructed from SS316 stainless steel throughout, offering excellent corrosion resistance in wet, chemical, and marine environments. The probe diameter and length are fully customisable to meet specific installation requirements, and a range of process fittings — including ½ NPT, ¼ NPT, ¼ BSP, ½ BSP, M8, M10, and M12 thread forms — allows the sensor to be installed directly into standard process pipework and vessels. The sensor complies with EN 60751 Class A accuracy, covering a temperature range of −50 °C to +250 °C, and is available with cable lengths up to 7 m or longer on request.
