SAJ Sanjing 8000b series frequency converter power: 0
2KW ~ 75KW
Voltage: single-phase 220V / three-phase 380V
8000b series enhanced frequency converter is a new product based on the company's 8000 Series and S350 series products and technical optimization according to the future technical development direction of frequency converter
8000b adopts a new parameter module, including speed sensorless vector control (SVC) and V / F control, which can realize high-performance control of motor, and the application has been greatly improved
1、 Stable operation
1
Software control improvement: accurate motor algorithm improves the operation speed, greatly improves the current control performance, strengthens the overcurrent suppression function (automatic current limiting, excavator characteristics, suppression of oscillation), reduces the number of trips and realizes stable operation
2
Hardware redundancy design; The load carrying capacity of switching power supply is greatly improved (24V reaches 200mA, 10V reaches 30mA), and dual channel power supply (between power board and control board) is adopted to ensure the stability of control power supply
The power of zero devices (the main component modules, rectifier bridges and capacitors are more than 2
5 times) and temperature resistance (- 40-85 degrees) are greatly improved to ensure the stable operation of the products
2、 Strong performance
1
Performance:
① 0
5Hz has 150% starting torque output, and smooth operation can be realized through simple adjustment
② Overcurrent capacity: 150% for 1 minute; 180% for 10 seconds; 200% instant
2
Functions:
① Speed tracking: ensure smooth start of large inertia load
② Short circuit protection: reduce frequency converter damage caused by external equipment failure
③ Leakage protection: the leakage probability is reduced
As long as the motor shell is led to the ground terminal of the frequency converter, the potential difference is below 30V
3、 Cost savings
1
Excellent bottom motor algorithm and optimized factory parameter value not only ensure strong torque output, but also greatly reduce debugging time and save time and effort
2
Custom function of output relay: let the end user define the output function, simplify the circuit design and save the cost
4、 Humanized design
1
The fan is automatically controlled to reduce the standby power of the frequency converter and reduce the operating noise
2
Three proofing paint spraying and nickel plating of copper bar on the internal circuit board enhance the environmental adaptability of the frequency converter
3
The wide voltage design of the input power supply can work normally at ac300-480v to enhance the regional adaptability of the frequency converter
