Variable Frequency Inverter Motor VFD Drives for Fans and Pumps

Features

Benefits

Dual digital tube

Double lines of LED display, monitoring 2 kinds of information meantime, like frequency, current, voltage, speed and PID data.

Smart restart

Instant power off continue running and speed tracking

S curve acceleration/deceleration mode

S curve acceleration/deceleration can reduce impact to the machine at start/stop time, and suitable for the start/stop process for loads of handling and transmission categories.
