MITSUBISHI inverter FR-D720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 0.4KW.
VVVF frequency control, vector control frequency conversion, direct torque control is a kind of AC - DC - AC frequency conversion.
The common drawback is that the input power factor is low, the harmonic current is big, and the DC circuit needs large energy storage capacity,
Renewable energy and can not be fed back to the power grid, which can not be carried out in the four quadrant operation MITSUBISHI Terminal module PDF datasheet FA-TH16YRAB20SL To this end, the matrix type of AC - AC variable frequency arises at the historic moment.
Because the matrix type alternating current frequency saves the intermediate DC link, thereby, the electrolytic capacitor with large volume and high price can be omitted MITSUBISHI Terminal module PDF datasheet.
It can achieve a power factor of L, the input current is sinusoidal and can run in four quadrant, the power density of the system is large.
Although the technology is not yet mature, but still attract a large number of scholars in-depth study.
In fact, the quality is not the indirect control current, flux, but the torque is directly used as the control to achieve MITSUBISHI Terminal module PDF datasheet. MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 7.5kw.
SLD converter rated current: 17.0A.
Structure and function: Standard model.
Type: CA FA-TH16YRAB20SL PDF datasheet.
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 FA-TH16YRAB20SL PDF datasheet.
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 FA-TH16YRAB20SL PDF datasheet.
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. Cable length: 2m.
RS-485 terminal unit conversion unit.
Applicable model: GT16. Convert connector to screw relay terminal.
According to the location of the connection equipment distribution module. Positive common end use. "MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 1.5KW.
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 caalled rectification FA-TH16YRAB20SL PDF catalog.
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 fixeed frequency and a certain voltage of the inverter MITSUBISHI Terminal module PDF datasheet.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter. "
