Micctech has very successful experience in specific servo drives like wind turbines and construction hoist in interior market in China.Based on the high quality and strict quality control system, we have developed this S300 series frequency drive for general use, which has wider application and easier installation. S300 has two series: A for asynchronous motor and E for synchronous motor. For example S300A-2-4T 5.5k suits for 5.5kw asynchronous motor and S300E-2-4T 5.5K suits for 5.5k synchronous motor. Both them are 3 phase frequency drive, and rated voltage 400V.
Why choose Micctech variable frequency drive?
Micctech has made and developed the vfd since 2014, starting from make specific servo drives for interior enterprises. For example, servo drive for wind turbines and construction hoist. These projects requires extremely high quality about the frequency drive. And Micctech meets all the needs and wins much reputation for itself.

Advantages of Micctech VFDs are mainly in these sides:
1. Micctech VFD Suit for most of Asynchoronaus and synchoronause drive and support kinds of control method. For example:
Asynchoronous drive can choose No PG flux vector control, with PG flux vector control and V/F control;
For synchoronous drive, it can choose No PG flux vector control, with PG flux vector control.
2. Compatible encoder:
It support rotary transformer and ABZ incremental encoder.
3.Communication:
Modbus, CANopen and Profibus-DP.
4. Steady and reliable:
Micctech uses high-class electronic units, excellent design, conformal coating on PCBA and independent air flue, all them work together to ensure the VFD has longer life time.
5. High starting torque:
In No PG flux vector control mode, when output frequency is 0.25Hz, VFD can reach 150% rated torque; In PG flux vector control mode, when output frequency is 0Hz, VFD can reach 180% rated torque.
6. High torque precision:
In No PG flux vector control mode, torque control precision is less than 7.5%; In PG flux vector control mode, torque control precision is less than 5%.
7. Compact structure:
Book style structure saves room for whole electric cabnet. More VFDs can be installed in the same width cabinet.
