3. Core Product Features
Precise linear power adjustment: output DC value changes proportionally following analog command voltage, high regulation accuracy for constant power load control.
Built-in comprehensive fault diagnosis circuit, external alarm terminal for SCR short-circuit and over-current failure signal output.
Heavy current copper bus connection terminals, optimized high-current circuit layout to reduce heat loss under full-load operation.
Independent control power loop powered by 131VDC, stable operation unaffected by fluctuation of main 3-phase 97VAC input grid.
Obsolete original series; new replacement model: Control Concepts FUSION series three-phase DC SCR power controller.
4. Typical Application Range
Industrial resistance heating furnaces, metallurgy thermal processing production lines
Electroplating & electrolysis DC rectifier power source equipment
Heavy-duty DC motor speed regulation & excitation power supply
Chemical coating, plastic extrusion heating loop power control
5. Installation & Operation Instructions
Fix equipment vertically on solid metal base with mounting bolts, reserve ≥150mm ventilation space around heat sink for air circulation.
Confirm main input: 3PH 97VAC and auxiliary control input: DC131VDC match nameplate parameter before power-on test.
Connect external 0~10VDC control command signal to corresponding control terminal; verify wiring polarity correctly.
After energization, check cooling fans run smoothly without abnormal noise; stop operation immediately once overheat or fault alarm occurs.
Periodically clean dust accumulated on heat sink and internal PCB circuit every 3–6 months to avoid poor heat dissipation damage.
