Advantages of SN200MN Series frequency inverter
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.
