Inovance CS300-4T5.5GB Frequency Converter

The Inovance‑CS300‑4T5.5GB is a 5.5 kW special‑purpose lifting frequency converter from the Inovance CS300 series, designed for three‑phase 380‑480V crane and hoist equipment. As a professional VFD for small lifting machinery, the Inovance‑CS300‑4T5.5GB delivers strong low‑speed starting torque to effectively prevent hook slipping during heavy‑load lifting operations.

The Inovance‑CS300‑4T5.5GB supports both open‑loop vector and V/F control for asynchronous motors. Built‑in dedicated brake timing logic is a core highlight of the Inovance‑CS300‑4T5.5GB, perfectly matching hoist brake working sequences and improving site‑operation safety. This Inovance‑CS300‑4T5.5GB inverter tolerates wide grid voltage fluctuation, keeping stable output under harsh power‑supply conditions.

Complete fault protection covers over‑current, over‑voltage, short‑circuit and over‑temperature to protect motors and mechanical structures. Equipped with standard RS485 communication, the Inovance‑CS300‑4T5.5GB connects seamlessly with PLC and automation systems. Compact cabinet‑friendly layout lowers commissioning work. The Inovance‑CS300‑4T5.5GB is widely adopted for lifting, travelling and slewing drives, offering reliable, cost‑effective drive solutions for global material‑handling projects.
