TECHNICAL DATA

  Range of input voltage:180V~260V/320V~480V. It can drive the rated voltage 220V/380V three phase AC induction motor  

  Output frequency ranege:0~400hz

  Output of low speed nominal torque, secure operation

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

  Control mode: V/f control

  Start-up torque:0.5HZ/150%(SVC)

  PLC function(satisfying the controlling requirement of 15bit speed)

  PID adjuster(respectively setting the proportion/ integral calculus/ differential coefficient of feedback signal) 

  Automatic energy-saving operation and display energy-saving data online

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

  Programmable input and output terminal for controlling

  Control mode variable, great popularity

  Internally brake is installed, and it can quickly brake

  Internally adjustable function of PID is installed, simply closedloop control

  Inner port is RS-485, it supports standard agreement of MODBUS, and it can be controlled by computer network

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

  AVR: can output constant voltage automatically when input voltage is fluctuating

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

  QUICK/JOG function: users can look over the parameters which are different from the factory values

  Speed tracing function: smoothly start the running motor

  Fault protections: protect from over-current, over-voltage, under-voltage, over- temperature, phase fault, over-load etc

APPLICATION:

Fan, water pump, compressor

Weave and chemical fibre machine 

Injection machine

Petrochemical industry, metallurgy industry,cement machinery,machanism, belt

   transport industry

Drilling and piling machine

Food and carpentry machine

AND SO ON

DESIGN:

       Complete series design for air channel

   There are two choices of mounting mode for radiator,one is inner cabinet,the other

   is outer cabinet,and it is convenient for us to change the fan.The convenience

   for maintainance of frequency converter increases them to operate stablely in different

   industries such as weaving,printing, chemical fiber,paper manufacture, fiber forming,

   cement manufacturing and so on.

   Voltage design for broad electricity grid

   When input voltage is from -15% to 15%,it is safe to operate by frequency converter,

   and user does't need do anything.

   Self-inspection function safely

   Frequency converter is power on ,the system will start to inspect the software and

   hardware completely. The system has the function that suppress to modify and set

   the functional parameter in order to prevent user from modify the wrong functional 

   parameter

   Super defensive function

   It can supply user more than  twenty kinds  of fault defensive function and also support

   failure auto reset function to complete protection from frequency converter to motor and

   other equipment. It installs over-load protection equipment by lighting in order to

   remove the usual fault automaticly,and also improve the self-protection function

   as to the influence-fuzed mine.

       Standard manufacturing platform

  The platform get the processing through electrostatic prevention, corrosion prevention

       and dust proof.We have professional production line and strict management for
