Three phase ac motor drive of 380v, 400v, 415v, 420v, 440v, 460v

three phase ac motor drive


In our company, the three phase ac motor drives power range are from 0.75kW to 630kW in 380v, 400v, 415v, 420v, 440v, 460v integrated RS 485 & Modbus communication protocol for easy real time control for most kinds of applications, it can easy achieve soft start & stop to protect the ac motor from high-current impact and make the power grid more stable.

The three phase ac drive manufactured by us have lots of advantages, like high overload capacity: 60 seconds in 150% rated current and 20 seconds in 180% rated current; high speed control accuracy: less than 1% of the synchronous rotated speed at rated frequency; allow analog input/output: 2 programmable terminals for PID control in 0 - 10V or 0/4 - 20mA; Tracking the ac motor’s speed in real time when restart in instantaneous power off; etc. For the power above 5.5kW, LED and LCD keypads are available for option, means you can easy copy parameters from one ac motor drive to another in your production lines.
