Technical Specifications Operating Auxiliary Power: 24 V DC Signal‑Input Voltage Range: Power‑unit snubber‑circuit sampling signals Isolation: Galvanic isolation between high‑potential sampling circuits and control‑signal circuits Operating Temperature: 0 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Mounting Type: Internal plug‑in installation inside multi‑drive power unit Protection Class: IP20 Certifications: CE
Functional Features Samples voltage‑feedback signals from power‑module snubber circuits. Conditions high‑potential sampling signals and converts them into control‑logic‑compatible signal levels. Hardware over‑voltage fault‑detection function for snubber‑circuit abnormal conditions. Isolates high‑potential power‑unit circuits from low‑voltage control‑logic circuits. Outputs fault‑status feedback signals to main‑control board via internal connectors. On‑board LED indicators reflect basic signal‑sampling operating status.
Application Scenarios ACS800 multi‑drive converter cabinet power‑unit internal‑board spare‑part replacement. Metallurgy, paper‑making large‑power multi‑drive equipment maintenance and overhaul projects.
Installation Requirements Insert ASFC‑01C board into designated installation position inside ACS800 multi‑drive power unit. Tighten fixing screws to prevent loosening under cabinet‑vibration conditions. Fully insert and lock all input‑and‑output multi‑pin connectors. Ensure cabinet cooling‑airflow flows through board surface area for heat dissipation. Complete cabinet protective‑earthing following drive‑system grounding specifications. Ambient operating environment must stay within rated temperature‑humidity ranges without condensation.
