450 kW (600 HP) Variable Frequency Drive – SHZK 300N Series

Product Overview

The SHZK 450 kW (600 HP) variable frequency drive is a ultra high power AC drive built for very large pumps, mine winders, cement kilns, rolling mills and utility-scale fans. It uses sensorless vector control for high starting torque and accurate speed regulation, and includes a built-in PID controller, Modbus RTU communication and comprehensive motor protection. Every rating is factory tested before shipment, and the same platform runs from 0.75 kW up to 800 kW so spare parts and parameter settings stay consistent across your whole line.
