FR-HC2-H55K hpfr MITSUBISHI FR-HC2-H55K

MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 90KW.
Frequency converter is the application of frequency conversion technology and micro electronics technology, by changing the motor operating power frequency mode to control the AC motor power control equipment MITSUBISHI FR-HC2-H55K.
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit FR-HC2-H55K
Inverter by the internal IGBT to adjust the output power supply voltage and frequency,
According to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition to the,
Inverter has a lot of protection functions, such as over current, over voltage, overload protection and so on MITSUBISHI FR-HC2-H55K. MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 250KW.
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 FR-HC2-H55K.
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 FR-HC2-H55K MITSUBISHI FR-HC2-H55K MITSUBISHI.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity. Power: 7.5kw.
Purpose: to suppress the power harmonics.
Improve the power factor, reduce the input side of the high harmonic current FR-HC2-H55K MITSUBISHI.
Make sure that this option is installed in the FR--A820-03800 (75K) and FR-A840-02160 (75K) and above capacity and above capacity FR-HC2-H55K.
At the same time the installation options in the use of 75kW and above motor. (the IP55 series has a built-in DC reactor.)
According to the motorr power used to select the DC reactor MITSUBISHI FR-HC2-H55K.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.)
