three phase inverter for fire-extinguishing appliance

 

  

 

Basic feature:

 

 1.Range of input voltage:180V~250V/340V~460V. It can drive the rated voltage

   220/380V three phase AC induction motor

 2.Output of low speed nominal torque, secure operation

 3.Over-load/over-current/over-voltage/over-heating/over-torque/short-circuit protection

    function

 4.Automatic current limited, voltage stall prevention

 5.Control mode:vector control,V/f control,constant torque,sensorless vector control

 6.Start-up torque:0.5HZ/150%(SVC)

 7.Automatic energy-saving function

 8.The carrier of frequency is adjustable continuously and it's up to 15KHz

 9.Torque output with low speed,operate stable

10.10rogrammable input and output terminal for controll

11.Internally brake is installed, quickly brake

12.Standard communication interface RS485,PID and simple PLC internally stalled

13.Built-in step(8step)speed control: PID control, travers Control

14.PID adjuster(respectively setting the proportion/ integral calculus/ differential

    coefficient of feedback signal)

15.AVR: automatically keep the output voltage stable when input voltage is fluctuating

16. 6 multi-functional digital inputs(PNP&NPN),1 analog inputs,2 relay output,1 analog

    output,2 optical couple output

17.QUICK/JOG function: users can look over the parameters which are different from

     the factory values
