Frequency inverter

Frequency inverter

Feature:
1. Range of input voltage:180V~260V/320V~480V. It can drive the rated voltage
220V/380V of three-phase alternating current induction motor
2. Operation conveniently with big LED digital display screen and friendly user interface
3. Completely defensive function,for example:automatic limit current and
preventing the voltage stalled
4. Output of low speed nominal torque,secure operation
5. The carrier of frequency is adjustable continuously and it's up to 15KHz
6. Programmable input and output terminal for controlling
7. Control mode variable, great popularity
8. Internally brake is installed,and it can quickly brake
9. Internally adjustable function of PID is installed, simply closedloop control
10. Simply PLC(setting automatic cycle operation)
11. Inner port is RS-485, it supports standard agreement of MODBUS,and it can be controlled by computer network

Design:
1. 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.
2. 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.
3. 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
4. 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.
5. 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 production.
