MITSUBISHI inverter series: FR-A820.
Voltage level: three phase 200V.
Power: 15kw.
SLD converter rated current: 77A.
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 (compared with the FR-A700 series, to reduce the volume of equipment).
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.
Standard corresponding RS-485 communication (MITSUBISHI converter protocol, Modbus-RTU protocol) data transmission speed up to 115200bps.
Power: 30kw.
Purpose: to suppress the power harmonics.
Connected to the inverter input, can be used to improve the power factor, reduce the input side of the high harmonic current.
According to the motor power used to select AC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose MITSUBISHI FR-A820-15K-1(FR-A820-00770-2-60). ) MITSUBISHI inverter FR-E720 series
FR-A820-15K-1(FR-A820-00770-2-60)
Voltage level: 3 phase 200V.
Frequency converter capacity: 0.4KW.
In order to ensure the reliability of production, all production machinery in the design of power with drive, there is a certain amount of surplus.
When the motor can not run under full load, in addition to meet the requirements of power driven,
The surplus torque increases the active power consumption, resulting in the waste of electric energy MITSUBISHI FR-A820-15K-1(FR-A820-00770-2-60).
Speed control method of fan and pump equipment traditional by regulating the entrance or exit of the baffle, valve opening to regulate air flow and water flow
, the input power is large, and a large amount of energy consumption in the baffle, the valve in the process of closure.
When using variable frequency control, if the flow rate is reduced, the speed of the pump or fan can be reduced to meet the requirements MITSUBISHI FR-A820-15K-1(FR-A820-00770-2-60). Power: 55kw.
Voltage: 400V.
There are 100% braking torque output in continuous regeneration, which can correspond to the continuous regeneration operation of the pipeline control FR-A820-15K-1(FR-A820-00770-2-60) MITSUBISHI.
There is no need to install the braking unit for each frequency converter, which can reduce the comprehensive space and reduce the comprehensive cost FR-A820-15K-1(FR-A820-00770-2-60) MITSUBISHI.
Renewable energy can be used for other frequency converter, excess energy back to the grid, to achieve energy saving. Power: 0.4kw.
Purpose: to suppress the power harmonics.
Improve the power factor, reduce the input side of the high harmonic current FR-A820-15K-1(FR-A820-00770-2-60) MITSUBISHI.
Make sure that this option is installed in the FR-A820-03800 (75K) and FFR-A840-02160 (75K) and above capacity and above capacity FR-A820-15K-1(FR-A820-00770-2-60).
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-A820-15K-1(FR-A820-00770-2-60).
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.)
