Product Details

Technical Parameter

Product Overview:

This SN200MN 380V 0. 75kW series of frequency converter is a kind of high-performance vector converter that can be used to control and adjust the speed of three-phase. AC asynchronous motor. With good load adaptability, high-precision speed controllability, low-speed high-torque output performance, excellent overload capacity and abundant setting functions, it's widely applied in various automatic production equipment such as textile, machine tool, package, draught fan, water pump and paper-making, etc.

Advantages of SN200MN Series frequency inverter

Product Features:

1)Various voltage levels: it supports three voltage levels- singl phase 220V, three phase 220V, and three phase 380V

2) Rich control methods: in addition to the speed sensor vector control, sensorless vector control, V/F control, it also supports V/F separation control

3) Optional field bus: it supports two kinds of bus-Modbus-RTU and CANLINK

4) Rich types of encoders: it supports differential encoder, open collector encoder, rotary transformer, etc.

5)Brand new sensorless vector control algorithm

The new SVC(sensorless vector control) brings better low-speed stability, stronger low-frequency load capacity, and the support for SVC torque control

6)Strong background software: the background software can achieve the frequency converter parameters of the upload

download, real-time oscilloscope and other functions.
