"Power: 55kw.
Voltage: 200V.
Brake resistor, a kind of ripple resistance, is mainly used in the mechanical system of the inverter to control the speed of the motor,
Help the motor to be converted into heat energy due to the regenerative power of the motor.
Braking unit principle: the brake unit is composed of a high power transistor GTR and its driving circuit MITSUBISHI MM-EFS221M.
Its function is to link the discharge current braking resistor capacitor voltage or not in the range of the time consumed and the DC part "overpressure",
Need to add external braking components, in order to speed up the speed of the consumption of renewable energy MM-EFS221M "Power: 110kw.
Voltage: 200V.
Sine wave filter.
The voltage and current of the motor can be adjusted to a sine wave MITSUBISHI MM-EFS221M.
The sine wave filter is installed to the output terminal of the inverter.
Applicable to FR-A820-03800 (75K) above and FR-A840-02160 (75K) and above frequency converter.
Sine wave filter is equivalent to the operational characteristics of the sine wave power driver, can provide the following benefits.
Low noise.
No surge current.
Reduce motor loss (standard motor) MITSUBISHI MM-EFS221M. MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 5.5kw.
SLD converter rated current: 12.6A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
2 times the power consumption of the wind turbine and pump and the speed of the 3 power consumption is proportional to the speed of the rotating speed.
Through the speed control of the frequency converter to adjust the air flow, can reduce the power consumption.
Give full play to the performance of the motor.
The excitation current is always adjusted to the best state, which can improve the efficiency of the motor.
Load torque is smaller, can further improve energy efficiency.
For example, when a general motor is used, the optimal excitation control mode in the 4% motor load torque is about 30% more than that of the V/F control. MITSUBISHI inverter FR-A720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 55KW.
Inverter general area of domestic enterprises to occupy more than 80% of the market share,
Production of frequency converter, motor soft starter and other industrial automation control of the manufacturers, the use of heavy-dduty design products,
Overload capacity, with super large start and running capacity, improve the automatic detection, protection and control performance,
Can start and control any type of heavy duty motor,
Products have been widely used in metallurgy, mining, paper, chemicals, building materials, machinery, electricity, and construction systems and other industrial transmission areas MM-EFS221M MM-EFS221M.
