3 kW (4 HP) Variable Frequency Drive – SHZK 300N Series

Product Overview

The SHZK 3 kW (4 HP) variable frequency drive is a compact AC drive built for small workshops, packaging machines, small pumps and light-duty machine tools. 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.
