Inverters & Converters

Frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply. The Micctech frequency converter is mainly composed of rectifier (AC to DC), filtering, inverter (DC to AC), braking unit, drive unit, detection unit and micro-processing unit. The inverter adjusts the voltage and frequency of the output power supply by the opening and closing of the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the inverter has many protection functions. , Such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, frequency converters have also been widely used. The energy saving of the frequency converter is mainly manifested in the application of fans and water pumps. After the fan and pump load adopts frequency conversion speed regulation, the power saving rate is 20% to 60%. This is because the actual power consumption of the fan and pump load is basically proportional to the third power of the speed. When the average flow rate required by the user is small, the fan and pump adopt frequency conversion speed regulation to reduce the speed, and the energy-saving effect is very obvious. However, traditional fans and pumps use baffles and valves for flow adjustment, the motor speed is basically the same, and the power consumption does not change much. According to statistics, the electricity consumption of fans and pump motors accounted for 31% of the national electricity consumption and 50% of the industrial electricity consumption. It is very important to use variable frequency speed regulation device on this kind of load. At present, the more successful applications include constant pressure water supply, various types of fans, central air conditioners and frequency conversion speed regulation of hydraulic pumps.

S300 vector control Variable Frequency Drive suit for most asynchronous and synchronous motor. It's easy to use and install.

S300 series universal AC frequency converter is universal vector frequency converter for industrial control, mainly used to control and adjust three phase AC motor speed and torque. Attribute Rated Input Voltage:  400V HS Code:  8504409999 Suited Motor:  22kw / 30HP 18.5KW / 25HP Product Description Frequency inverters, widely known as VFD, variable frequency drive, frequency converter, is a kind of drive for adjusting torque and speed of ac motors. With PLC, vfd can realize smart control. AC Frequency Converter has been installed in machine tools, construction hoists, brick making machines and other industries. Micctech technology has been sell its servo drives since the year of 2014. With 121 employees and over half belongs to R&D department. Powerful developing technology satisfy different customer’s needs.

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. Variable frequency dives system are widely used in paper making, food and beverage, packing, construction material, textile, machine tools, water supply and ventilation, rubber and plastic extrusion, etc. Frequency drive, also called servo drive, ac drive or ac inverters, is used to adjust motor speed and torque. In smart control industry, variable frequency drives are used to save energy and increase working efficiency. Variable frequency dives system are widely used in paper making, food and beverage, packing, construction material(such as brick making, construction hoist), textile, machine tools, water supply and ventilation, rubber and plastic extrusion, etc. Advantages of Micctech VFD system are mainly in these sides: 1. Micctech VFD system 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 system 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 VFD system can be installed in the same width cabinet.
