MITSUBISHI inverter FR-E720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 7.5KW.
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.
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.
The operation, monitoring, parameter modification and other operations can be carried out by computer or PLC.MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 0.75KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%) FR-E720-7
FR-E720-7.5K5K MITSUBISHI.
Starting with power frequency power supply, the starting current is 6~7 times of the rated current, therefore, the impact on the mechanical and electrical.
The inverter drive can be smoothly start (start time longer) FR-E720-7.5K MITSUBISHI.
The starting current is 1.2~1.5 times of the rated current, and the starting torque is 70%~120% rated torque;
For the inverter with the torque automatic enhancement function, the starting torque is more than 100%, which can start with full load. Power: 15kw.
Voltage: 400V.
Purpose: high frequency braking resistor.
The braking ability provided by the braking capacity is larger than that provided by the external braking resistor FR-E720-7.5K MITSUBISHI.
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 series: FR-F842.
Voltage level: three phase 400V.
Power: 400kw.
SLD converter rated current: 866A.
Structure and function: the rectification part is off type.
Type: CA.
Substrate coating: have.
Energy saving by high efficiency motor.
Reduce standby power consumption.
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 FR-E720-7.5K.
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 correspondinng signal,
Therefore, the inverter and other built-in fan and inverter cooling fan synchronous operation FR-E720-7.5K.
Can reduce the power consumption in the stop.
