Power: 11kw.
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.
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.
MYS type resistor can be used. But please pay attention to the allowable brake use rate.
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.

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 MITSUBISHI FR-ABR-H11K.
Through the speed control of the frequency converter to adjust the air flow, can reduce the power consumption
FR-ABR-H11K
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 MITSUBISHI FR-ABR-H11K. MITSUBISHI inverter series: FR-F842.
Voltage level: three phase 400V.
Power: 355kw.
SLD converter rated current: 770A.
Structure and function: the rectification part is off type.
Type: CA.
Substrate coating: have.
Energy saving by high efficiency motor.
Reduce standby power consumption MITSUBISHI FR-ABR-H11K.
DC24V external power supply, the input MC signal can be stopped after the motor for the OFF, in the motor drive for the ON.
Standby power management can be carried out by means of frequency converter to realize the power consumption reduction of standby time.
According to the temperature of the inverter cooling fan, the operation of the inverter can be controlled.
According to the operating conditions of the inverter cooling fan output the corresponding signal,
Therefore, the inverter and other built-in fan and inverter cooling fan synchronous operation.
Can reduce the power consumption in the stop. MITSUBISHI inverter series: FR-A820.
Voltage level: three phase 200V.
Power: 3.7kw.
SLD converter rated current: 25A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
Parameters can be selected by 4 different rated current and different overload rating (SLD (ultra light load) rated, LD (light load) rating, ND (general load) rating, HD (weight).
Type load) for selection.
You can choose the most suitable frequency converter for use; and by selecting a transducer with a SLD or LD rated level,
Be able to reduce the size of the device (compaared with the FR-A700 series, to reduce the volume of equipment) FR-ABR-H11K.
For applications that require high torque at low speeds, the HD rating is the most suitable.
The controller is used to control and monitor the frequency converter through the network FR-ABR-H11K.
Standard corresponding RS-485 communication (MITSUBISHI converter protocol, Modbus-RTU protocol) data transmission speed up to 115200bps.
