GE Fuji AF-300 P11 AC Variable Frequency Drive

Feature & Principle

It is a classic V/F control inverter jointly developed by GE and Fuji. It adjusts output frequency and voltage proportionally to realize asynchronous motor speed regulation. It has dedicated energy-saving mode for centrifugal pump and fan, built-in PID constant pressure control, flying restart function after power loss. It integrates overcurrent, overvoltage, undervoltage, overheat, phase loss and motor overload protection. Optional Profibus-DP communication module for upper system linkage. This series has been discontinued and mostly used as maintenance spare parts for old equipment.
