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 MKD2 Series is a single-phase, dual-channel, DC-controlled AC solid state relay (SSR) designed for reliable, silent switching of resistive and inductive AC loads in industrial and commercial control systems. Each unit houses two independent switching channels within a single compact black housing, enabling two separate AC loads to be controlled simultaneously from a single device — saving panel space and wiring time compared to installing two separate SSRs. The MKD2 accepts a DC control voltage of 4–32 VDC, making it directly compatible with PLC outputs, microcontroller I/O, and standard industrial control signals. The AC load side supports voltages from 24 to 480 VAC, covering 110 V, 220 V, 380 V, and 480 V systems worldwide. Load current ratings of 25 A, 40 A, 60 A, and 80 A are available, with all variants sharing the same physical footprint for easy interchangeability. Zero-crossing trigger technology ensures that switching occurs at the natural zero-crossing point of the AC waveform, minimising electrical interference (EMI) and extending the service life of both the relay and the connected load. Individual LED status indicators for each channel provide instant visual confirmation of relay state, simplifying commissioning and fault-finding. The unit is CE certified and constructed from fire-retardant ABS with a dielectric strength of 2500 Vrms between input, output, and base.
