QIJEN Variable Frequency Inverter ( VFD )

Warranty:- one year, Product introduction:
QIJEN-QJ2000 series is a universal frequency converter, which can be widely used in various types of induction motor speed control. Products are designed based on 32 bit DSP, adopting international advanced vector control algorithm with high performance and high precision motor drive control to improve its quality reliability and environment adaptability at the same time, strengthen easy operation for user. It achieves function optimization, more flexible application, and more stable performance.

Main features:

(1) Double specifications of the design: heavy load model (150% load 1 minute) and light load patterns (120% load 1 minute) dual specifications;

(2) The use of fourth generation IGBT module combined with the characteristics of 175 maximum junction temperature, which adopts innovative PWM modulation method to further reduce the switching loss and makes the inverter run up to50 ambient temperature without de-rating;

(3) Advanced independent air duct design prevents pollutants from entering the electronic system area and efficiently improve protection effect to adapt to all kinds of complicated and worse site condition such as GRANITE application s; meanwhile; independent air duct could effectively solve the heat dissipation problem of control cabinet;

(4) Compact size and support parallel installation to save installation space;

(5) Adopt advanced flux estimation technology, and speed estimation technology and so on to realize high-performance sensor less speed vector control so as to unleash motor s best performance;

(6) Parameter auto tuning function: static parameter auto tuning function, output cable short circuit deduction. Motor impedance checking etc;

(7) Built-in Modbus communication protocol to make automatic system integration convenient; Excelent inbuilt PID and efficient inbuilt PLC with time cycle and direction.

(8) Its wide voltage range design ensures QJ2000 frequency inverter s excellent adaptability to grid fluctuation;

(9) Thicken three-anti paint (anti-humidity, anti-dust, anti-fungal) protection to enforce its reliability in the worse working envitonment;

(10) Available upto 500kw on 200/400v ranges.

(11) One year flexible warranty.
