MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 500KW.
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 FX3U-4LC.
Why is the frequency of the inverter voltage proportional to the change?
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 motor FX3U-4LC.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity FX3U-4LC.
Analog input points: 4 points (thermocouple, PT, constant voltage input).
Output points: transistor output 4 points, 4 point CT input.
Weight: 0.4KG.
Temperature sensor with 4CH input control output,
Double position control, standard PID control,
Heating and cooling PID control, cascade control MITSUBISHI FX3U-4LC.
By using the combination of the analog output module,
PID control of voltage or current can be realized.
New with cascade control. Through the master / slave station of the 2 controllers,
According to the temperature change caused by external disturbance, the temperature can be adjusted quickly MITSUBISHI FX3U-4LC.
Can connect FX3GA/FX3G, FX3GE, FX3U series.
When connecting to FX3UC or FX3GC, you need FX2NC-CNV-IF or FX3UC-IPS-5V. Application: extended input module with input power transfer cable MITSUBISHI FX3U-4LC.MITSUBISHI inverter FR-D740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 3.7KW.
The internal and back of the inverter structure considering the cooling effect, the relationship between the upper and lower ventilation is also important,
Therefore, in order for the type of unit, hanging on the wall to the vertical position, the installation of vertical as possible.
Transducer can be used to drive a single phase motor? Can single phase power supply be used?
Basically can not be used. For a single phase motor with governor switch, the auxiliary winding will be burnt when the speed is beloow the operating point;
For the capacitor start or capacitor operation mode, the capacitor explosion will be induced FX3U-4LC.
The inverter power supply is usually 3, but the capacity for small, single-phase power is also useful functioning aircraft.
