PID target value can be set directly from the operator panel. Flexible change settings.
In the 1 inverter, through the PID control of parallel connection pump (up to 4 units) can adjust the amount of water and so on FR-LU08 datasheet PDF catalog FR-LU08 PDF datasheet FR-LU08
1 pumps driven by parallel connection of the pump machine, in addition to the pump for power frequency drive.
The number of power frequency driven pump, according to the automatic adjustment of water.
The liquid crystal panel options (FR-LU08) can be converted to a more intuitive display unit% units FR-LU08 datasheet PDF catalog FR-LU08 PDF datasheet.
Through the use of wind, temperature and other familiar units can be simple to maintain and adjust the display. MITSUBISHI inverter FR-D720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 0.2KW.
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 FR-LU08 datasheet PDF catalog FR-LU08 PDF datasheet. 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.
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, thee quality is not the indirect control current, flux, but the torque is directly used as the control to achieve FR-LU08 datasheet PDF catalog FR-LU08 PDF datasheet. Power: 280kw.
Voltage: 400V.
The power factor of the input power factor is up to 0.999 and above (100% load) FR-LU08 datasheet PDF catalog FR-LU08 PDF datasheet.
Can be connected to multiple inverters, to achieve a common DC bus mode.
Equipped with standard power retrogradation function.
