MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 18.5KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%) FX3GE-24MR/DS datasheet PDF catalog FX3GE-24MR/DS PDF datasheet FX3GE-24MR/DS
Starting with power frequency power supply, the starting current is 6~7 times of the rated current, therefore, the impact on the mechanical and electrical.
The inverter drive can be smoothly start (start time longer).
The starting current is 1.2~1.5 times of the rated current, and the starting torque is 70%~120% rated torque;
For the inverter with the torque automatic enhancement function, the starting torque is more than 100%, which can start with full load FX3GE-24MR/DS datasheet PDF catalog FX3GE-24MR/DS PDF datasheet. Power: 30kw.
Voltage: 200V.
The power factor of the input power factor is up to 0.99 and above (100% load).
Can be connected to multiple inverters, to achieve a common DC bus mode.
Equipped with standard power retrogradation function FX3GE-24MR/DS datasheet PDF catalog FX3GE-24MR/DS PDF datasheet. MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 3.7kw.
SLD converter rated current: 8.3A.
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. Number of input channnels: 4 channels FX3GE-24MR/DS datasheet PDF catalog FX3GE-24MR/DS PDF datasheet.
Voltage input: DC-10~10V.
Current input: DC4~20mA, DC-20~20mA.
Programmable logic controller: FX2NC, FX3UC.
By using analog input module and output module,
Can be inpput and output analog (voltage, current, etc FX3GE-24MR/DS datasheet PDF catalog FX3GE-24MR/DS PDF datasheet. ).
Indispensable analog control in FA control,
It is easy to implement on a programmable logic controller.
