MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 110KW.
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 FX3U-48MT/DSS Hardware Edition Manual FX3U-48MT/DSS USER'S MANUAL.
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit FX3U-48MT/DSS
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 FX3U-48MT/DSS Hardware Edition Manual FX3U-48MT/DSS USER'S MANUAL. MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 11kw.
SLD converter rated current: 25.0A.
Structure and function: Standard model.
Type: CA.
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 FX3U-48MT/DSS Hardware Edition Manual FX3U-48MT/DSS USER'S MANUAL.
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.
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. Function: input / output module (internal service power supply).
Input / output points: 32 points
Input points: 16 points.
Output points: 16 points.
DC5V internal consumption current: 965mA.
DC24V internal consumption current: 250mA.
Input / output mode: DC input (drain / source) / transistorr (drain) FX3U-48MT/DSS Hardware Edition Manual FX3U-48MT/DSS USER'S MANUAL.
In order to extend the input output of the device.
Also has a built-in power supply products.
The maximum number of points for the input and output is 256.
Expansion modulee: up to 16 units (in addition to the power expansion module)
The total number of CC-Link, AnyWireASLINK, and Bitty series of remote I/O is 512 points FX3U-48MT/DSS Hardware Edition Manual FX3U-48MT/DSS USER'S MANUAL.
