Thyristor Power Controllers & Solid State Relays
The CD Automation range of Single & 3 Phase SCR Power Controllers, offers industrial users a reliable, efficient solution for precise thermal process management. By delivering fast, infinitely variable thyristor-based power control, it ensures stable temperature regulation, improved product quality, extended heater lifespan, and reduced maintenance compared to mechanical alternatives. One of its standout advantages is advanced power optimisation. By synchronising multi‑zone loads, the controller prevents energy overshoot, smooths power demand, and helps avoid costly utility penalties. Users benefit from reduced energy costs, improved power factor, minimal voltage flicker, and lower harmonic distortion—supporting both operational efficiency and grid stability. Its compact, multi‑channel design (up to 24 zones) significantly reduces cabinet space, wiring complexity, and installation time, while built‑in diagnostics—covering heater integrity, SCR health, and fuse status—streamline troubleshooting and reduce downtime. Seamless integration is ensured through compatibility with leading fieldbus protocols, including Modbus, Profinet, and Ethernet/IP. Free PLC libraries and tools enable rapid commissioning, while USB and wireless app connectivity simplify configuration and monitoring. In short, CD Automation’s SCR Power Controller delivers precise temperature control, energy efficiency, simplified engineering, advanced diagnostics, and effortless connectivity, empowering manufacturers to optimise performance and lower operating costs.
Temperature & Process Controllers
The CD66 PID Controller from CD Automation is a compact, easy-to-use solution for precise temperature and process control. Built in a durable 48 × 48 mm (1/16 DIN) format with IP65-rated front protection, it delivers reliable performance in tough industrial environments while remaining simple to operate. Designed to save time and reduce errors, the CD66 features a bright, clear display and four customizable keys, giving operators fast access to essential functions like auto/manual switching, setpoint selection, and process start or stop. Its flexibility stands out, with inputs for thermocouples, RTDs, voltage, current, and millivolt signals, plus dedicated current transformer monitoring to detect load faults early. Multiple outputs—including solid-state drivers, relays, and analog retransmission—ensure seamless control of heaters, coolers, and other equipment. Advanced features such as auto-tuning PID control, soft-start protection, and programmable ramp and dwell cycles help optimize process stability, reduce energy waste, and protect sensitive materials. Built-in alarms and diagnostics further minimize downtime by identifying heater and loop issues before they become critical. With RS‑485 Modbus RTU communication and USB configuration, the CD66 integrates easily into new or existing systems, giving manufacturers a powerful, dependable controller that improves efficiency, consistency, and process quality.
EMI Single & 3 Phase Power Filters
Experiencing flickering screens, unstable networks, or unexplained electronic disruptions? These issues often trace back to Electromagnetic Interference (EMI). CD Automation’s range of single and three-phase EMI Power Filters delivers the solution. Engineered to suppress interference across a broad spectrum (10 kHz to 10 GHz), our filters protect sensitive and mission-critical equipment by eliminating both common and differential mode noise. They ensure your systems remain compliant with EMC standards, operate reliably, and avoid costly downtime caused by power disturbances. Whether your operations involve digital control systems, industrial heating processes, or precision instrumentation, our filters provide the clean, stable power your equipment depends on. Let CD Automation help you eliminate EMI issues and keep your systems running at peak performance.
