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.

The TC-K14B is a fast-response K-type thermocouple engineered for applications where rapid, accurate temperature measurement is essential. Unlike conventional sheathed thermocouples, the TC-K14B features an exposed welded-bead junction with minimal thermal mass, enabling it to detect temperature changes within fractions of a second. This makes it the preferred choice for dynamic temperature monitoring tasks in research, testing, and industrial quality control environments. The sensor is constructed from a fine-gauge Chromel-Alumel (K-type) thermocouple wire pair, twisted together and insulated with a flexible fiberglass braid. The green-and-white color coding of the lead wire follows the international K-type thermocouple standard, providing clear polarity identification. The fiberglass insulation offers excellent thermal resistance and flexibility, allowing the sensor to be routed through confined spaces and around complex geometries without risk of insulation damage. At the instrument end, the TC-K14B is fitted with a standard miniature K-type quick-disconnect connector (green housing, labeled 'K NiCr+ / NiAl−'), which is compatible with a wide range of handheld thermometers, data loggers, and temperature indicators that accept the IEC 60584 / ANSI miniature thermocouple connector standard. The plug-and-play design eliminates the need for field wiring, enabling rapid deployment and sensor replacement without tools or specialist knowledge. The lead wire length is fully customizable, making the TC-K14B adaptable to installations where the measurement point is located at a significant distance from the instrument. As part of the PIDMaxWell range of temperature measurement solutions, the TC-K14B is designed to integrate seamlessly with PIDMaxWell PID temperature controllers, temperature transmitters, and compatible third-party instrumentation.
