MITSUBISHI inverter series: FR-A820.
Voltage level: three phase 200V.
Power: 37kw.
SLD converter rated current: 187A.
Structure and function: Standard model FR-E520S-0.4K to 2.2K-EC PDF.
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) FR-E520S-0.4K to 2.2K-EC
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) FR-E520S-0.4K to 2.2K-EC PDF.
For applications that require high torque at low speeds, the HD rating is the most suitable FR-E520S-0.4K to 2.2K-EC Manual.
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 FR-E520S-0.4K to 2.2K-EC PDF. Output points: 2 points.
Output form: transistor output.
Weight: 0.02kg.
Function expansion board is used in the FX3SA, FX3S, FX3GA, FX3G, FX3GE on the small number of input and output extension of the product,
Can be built into PLC MITSUBISHI INSTRUCTION MANUAL. MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 500KW.
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 INSTRUCTION MANUAL.
Why is the frequency of the inverter voltage proportional to the change?
The electromagnetic torque off 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 MITSUBISHI INSTRUCTION MANNUAL FR-E520S-0 FR-E520S-0.4K to 2.2K-EC INSTRUCTION MANUAL. 4K to 2.2K-EC Manual.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity.
