"MITSUBISHI inverter FR-E720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 0.75KW.
The use of frequency converter motor is in order to speed, and reduce the starting current.
In order to produce a variable voltage and frequency, the device is the first power of the AC power conversion to DC (DC), the process is called rectification.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter).
General inverter is the DC power supply inverter for a certain fixed frequency and a certain voltage of the inverter.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter.
Inverter output waveform is simulated sine wave, mainly used in three-phase asynchronous motor speed control, and also called frequency governor. "
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 MITSUBISHI FR-E720S-0
FR-E720S-0.75K75K.
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 below the operating point;
For the capacitor start or capacitor operation mode, the capacitor explosion will be induced MITSUBISHI FR-E720S-0.75K.
The inverter power supply is usually 3, but the capacity for small, single-phase power is also useful functioning aircraft. Power: 15kw.
Voltage: 400V.
There are 100% braking torque output in continuous regeneration, which can correspond to the continuous regeneration operation of the pipeline control.
There is no need to install the braking unit for each frequency converter, which can reduce the comprehensive space and reduce the comprehensive cost MITSUBISHI FR-E720S-0.75K.
Renewable energy can be used for other frequency converter, excess energy back to the grid, to achieve energy saving. Power: 15kw.
Voltage: 400V.
The power factor of the input power factor is up to 0 MITSUBISHI 3 phase 200V converter. 99 and above (100% load).
Can be connected to multiple inverters, to achieve a common DC bus mode MITSUBISHI 3 phase 200V converter.
Equipped with standard power retrogradation function. MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 315KW.
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 MITSUBISHI 3 phase 200V converter.
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 mmotor MITSUBISHI FR-E720S-0 FR-E720S-0.75K. 75K.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity.
