Brand: MITSUBISHI
Name: 3 phase 400V converter
Model: FR-A740-3.7K-CHT
MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 3.7KW.
FR-A700 converter products are suitable for all kinds of high load requirements of the equipment.
Such as lifting, lift, printing and dyeing, printing and dyeing, material coiling and other general occasions.
High level driving performance.
Unique sensorless vector control mode,
A wide variety of mechanical equipment can be operated at high precision in the super low speed region without the need of the encoder.
With torque control mode,
And in the speed control mode can use the torque limit function.
With vector control function (with encoder),
Frequency converter can achieve position control and fast response, high precision speed control (zero speed control, servo lock, etc.) and torque control.

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 MITSUBISHI FR-A740-3.7K-CHT.
Through the speed control of the frequency converter to adjust the air flow, can reduce the power consumption FR-A740-3.7K-CHT
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 FR-A740-3.7K-CHT. The frequency of a transducer can be set by a digital signal from an external BCD or binary code.
BCD code 3 (maximum 999).
BCD code 4 (maximum 9999).
Binary code 12 (max FFFH).
Binary code 16 (max FFFFH). Power: 15kw.
Voltage: 400V.
Purpose: high frequency braking resistor MITSUBISHI FR-A740-3.7K-CHT.
The braking ability provided by the braking capacity is larger than that provided by the external braking resistor.
Can also be connected without built-in brake transistor inverter.
Three types of discharge resistors are available FR-A740-3.7K-CHT MITSUBISHI.
Please select according to the required braking torque. MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 250KW FR-A740-3.7K-CHT MITSUBISHI.
The main circuit of the inverter can be divided into two categories in general: voltage type is the voltage source of the DC converter for AC inverter,
The filtering of the DC circuit is the capacitance; the current mode is the DC conversion of the current source to the AC inverter,
The DC loop filter is the inductor FR-A740-3.7K-CHT MITSUBISHI.
Why is the frequency of the inverter voltage proportional to the chhange?
The electromagnetic torque of any motor is the result of the interaction between the current and the magnetic flux, the current is not allowed to exceed the rated value, otherwise it will cause the heating of the mmotor MITSUBISHI FR-A740-3 FR-A740-3.7K-CHT. 7K-CHT.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity.
