Technical Specifications Operating Supply Voltage: Matched host equipment power voltage range Heat‑sink Material: Extruded aluminum alloy Operating Temperature: ‑10 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mounting Form: Internal equipment fixed installation Protection Grade: IP20 inside cabinet Certifications: CE
Functional Features Provides high‑efficiency heat dissipation for internal power semiconductor components of host equipment. Realizes power circuit signal transmission and current conduction function. Adopts integrated heat‑sink and circuit‑board composite structure. Matches mechanical installation dimension and electrical interface of host power unit. Supports long‑term high‑load continuous operation under industrial cabinet environment.
Application Scenarios Corresponding ABB power drive equipment internal heat‑sink board spare‑part replacement. Industrial power unit overhaul and maintenance project.
Performance Parameters Heat dissipation capacity: Matches host equipment rated power consumption requirement Fault tolerance: Module mechanical damage will trigger over‑temperature protection of host equipment Mean Time Between Failures: Exceeds 210000 hours Shock and vibration resistance: Complies with industrial power equipment spare‑part standard.
Installation Requirements Install assembly into designated position inside host power equipment, ensure heat‑sink contact surface fits closely with power components. Tighten fixing screws according to manufacturer‑recommended torque value to guarantee heat conduction efficiency. Follow host equipment protective earth grounding specification strictly. Confirm power circuit wiring definition matches terminal specification before power‑on. Replacement operation must comply with high‑voltage electrical safety operation procedure. Reserve sufficient ventilation clearance around heat‑sink for air convection heat dissipation. Ambient installation environment stays within defined temperature and humidity range without condensed moisture.
