FR-BU2-7.5K | MITSUBISHI FR-BU2-7.5K Brake unit

Brand: MITSUBISHI
Name: Brake unit
Model: FR-BU2-7.5K
Power: 7.5kw.
Voltage: 200V.
Purpose: high frequency braking resistor.
The braking ability provided by the braking capacity is larger than that provided by the external braking resistor.
Can also be connected without built-in brake transistor inverter.
Three types of discharge resistors are available.
Please select according to the required braking torque.

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-BU2-7.5K.
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit FR-BU2-7.5K
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-BU2-7.5K. Power: 22kw.
Purpose: high frequency braking resistor.
The use rate of the built-in regenerative brake of the transducer can be promoted.
When using the FR-ABR type brake resistor, the short circuit piece between the terminal PR-PX is removed. Does not remove the short circuit chip will lead to overheating of the brake resistor MITSUBISHI FR-BU2-7.5K.
The utilization rate of the regenerative braking should be less than the allowable brake use rate in the above table.
With the operating frequency of the brake resistor to reach 300 degrees C or higher, it is necessary to take protective measures and cooling FR-BU2-7.5K MITSUBISHI.
MYS type resistor can be used. But please pay attention to the allowable brake use rate FR-BU2-7.5K MITSUBISHI.
Do not remove the terminal P/+ and P1 between the short circuit chip, in addition to connecting the DC reactor.
The installation of thermal relay, to avoid overheating and burn the braking resistor. Power: 37kw.
Voltage: 400V.
There are 100% braking torque output in continuous regeneration, whicch can correspond to the continuous regeneration operation of the pipeline control FR-BU2-7 FR-BU2-7.5K. 5K MITSUBISHI.
There is no need to install the braking unit for each frequency converter, which can reduce the comprehensive space annd reduce the comprehensive cost MITSUBISHI FR-BU2-7.5K.
Renewable energy can be used for other frequency converter, excess energy back to the grid, to achieve energy saving.
