Technical Specifications Rated operating voltage 230 V AC, dual‑phase power input. Rated power 280 W, rotating speed 2700 RPM. Air volume 580 m³/h. Operating temperature range ‑20 ℃ to +70 ℃, storage temperature ‑40 ℃ to +85 ℃. Built‑in thermal overload protection. Equipped with tachometer signal output interface. Weight approximately 2.1 kg.
Functional Features Delivers forced cooling airflow for power modules and heat sink assemblies. Built‑in tachometer outputs real‑time rotating speed feedback signal to control system. Mechanical structure resists vibration in industrial cabinet environment. Supports continuous 24‑hour non‑stop operation. Tachometer signal enables upper system to monitor fan running health status.
Application Scenarios Cooling fan spare part for ABB high‑power ACS series inverter cabinets. Widely used in metallurgy, mining and heavy‑duty industrial drive equipment maintenance.
Performance Parameters Large air volume heat dissipation performance. Stable high‑speed continuous rotation. Accurate rotating speed feedback output. Strong anti‑vibration mechanical performance.
Material Composition Metal fan housing, aluminum alloy impeller. High‑temperature resistant brushless motor assembly. Thermal protection circuit board and tachometer signal circuit. Insulated power wiring terminals.
Structural Characteristics Square metal frame structure. Centrifugal dual‑air‑inlet impeller inside frame. Rear side fitted with power and signal wiring terminals. Reserved mounting holes for cabinet fixed installation.
Working Principle After power‑on supply, internal motor drives centrifugal impeller to rotate at rated speed. Ambient air is sucked in from double side air inlets and blown toward power unit heat sink to take away heat. Tachometer circuit converts real‑time rotating speed into pulse signal and sends to drive control board.
Installation Requirements Completely cut off inverter main power and auxiliary control power before replacement. Align mounting holes and fasten fan module to cabinet mounting bracket. Connect AC power cable and tachometer signal cable to corresponding terminals. Restore power supply, verify fan rotation direction and tachometer speed feedback value.
