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.
Power: 75kw.
Voltage: 200V.
Sine wave filter.
The voltage and current of the motor can be adjusted to a sine wave.
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 MITSUBISHI FR-F840-00083-2-60
FR-F840-00083-2-60
Low noise.
No surge current.
Reduce motor loss (standard motor). Voltage level: three phase 400V.
Applicable motor capacity: 400kw.
Substrate coating: have.
Built in DC reactor.
The operating frequency of the fixed alternating current is converted to DC power. MITSUBISHI inverter FR-F720 series MITSUBISHI FR-F840-00083-2-60.
Voltage level: three phase 200V.
Frequency converter capacity: 75KW.
When the ring is opened, the frequency converter is provided with a load of the motor when the motor is operated with a load at a given frequency,
The range of the motor speed in the rated slip ratio (1%~5%) changes.
For the requirements of relatively high precision, even if the load changes are also required to operate at a given speed of the occasion,
Inverter with PG feedback function can be used (selection) MITSUBISHI FR-F840-00083-2-60.
If the given acceleration time is too short, the output frequency of the inverter is far more than the change of the speed (electric angular frequency),
Converter will be due to flow over the current trip, the operation stopped, which is called stall. MITSUBISHI inverter series: FR-A820.
Voltage level: three phase 200V.
Power: 30kw.
SLD converter rated current: 154A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
Parameters can be selected by 4 different rated current and different overload rating (SLD (ultra light load) rated, LD (light load) rating, ND (general load) rating, HD (weight).
Type load) for selection.
You can choose the most suitable frequency converter for use; and by selecting a transducer with a SLD or LD rated level,
Be able to reduce the size of the device (compared witth the FR-A700 series, to reduce the volume of equipment) FR-F840-00083-2-60.
For applications that require high torque at low speeds, the HD rating is the most suitable.
The controller is used to control and monitor the frequency converter through the network FR-F840-00083-2-60.
Standard corresponding RS-485 communication (MITSUBISHI converter protocol, Modbus-RTU protocol) data transmission speed up to 115200bps.
