Description
JR***0
Open-Loop Vector Inverter
JR***0 series
open-loop vector inverter adopts advanced DSP control system,
incorporates built-in speed less sensor vector control and V/F
control. The whole series adopts G/P integrated design ,positions
at OEM customers in middle and high-end markets and load
application of fan pumps with specific requirements and can be
widely applied where there are high requirements at speed control
precision, torque response speed and low- frequency output
features.
We make from 5.5KW to **0 KW
including 3 phase **0V ,also have the special 3 phase **0V
,.Welcome choice by our product.
