CD Automation CD3000S-1PH Solid Switch With Power Module

CD Automation CD3000S-1PH Solid Switch With Power Module is a compact, single‑phase thyristor power controller designed to replace contactors for resistive loads and infrared heating, with 1PH models from 10 A to 90 A and a power module integrated for streamlined installation. It accepts a broad control range—a 24 V to 480 V supply (600 V on request) for the unit and 230 V (110 V option) for the control electronics—and supports SSR, or an analog 4–20 mA or 0–10 V input (the analog option is available on units from 15 A to 90 A). Firing can be zero crossing or burst, and the unit includes microprocessor‑based fault diagnostics with a heater‑break alarm (discrimination better than 20%) plus a latched/resettable alarm, while a 1 A at 230 V relay output provides signaling for external interlocks or alarms. Mounting is DIN rail‑friendly (up to 90 A included) with IP20 protection, and approvals cover EMC with CE and cUL; optional cULus is available on basic units. The CD3000S‑1PH is built for thermal control tasks, suitable for heating elements and resistive loads in industrial automation, offering automatic calibration of one or more units via a dedicated digital input or per‑unit calibration button.
