KE300A-07 Series High Protection Textile Special Inverter

KE300A-07 series high-protection textile special inverter is a high-performance and high-reliability inverter for the textile industry. Based on the KE300A series vector inverter, adding advanced features for textile applications. For example, the current limiting technology and hardware optimization design for textile, and add the swing frequency application, fixed length / fixed diameter, crawling positioning etc. At the air inlet, a dust cover that can be easily removed is added, and the customer can disassemble and clean it in time. It can be adapted to the occasions with high pollution levels in the textile industry (high cotton, high temperature, high humidity, etc.)

Features of KE300A-07 Series High Protection Textile Special Inverter

Unique air-cooled design can prevent cotton wool from entering the air duct to block the air duct and fan; the air inlet is added a dust cover that can be easily removed, which is convenient for customers to disassemble and clean in time;
Easy to install and debug
Rugged EMC design
Adopt modular design, the configuration is very flexible
The main control system uses 32-bit high-speed DSP, integrated PG-free vector control, V/f control, and torque control.
With swing frequency, fixed-length/fixed diameter, crawling positioning and other functions.
Perfect protection functions: overvoltage/undervoltage protection, inverter overheat protection, ground fault protection, short circuit protection, overcurrent protection, overload protection, etc.
