4.0KW 380V Frekvensomformer

【PREMIUM QUALITY】- This VFD adopts the US intel and SILICON LABS chip. With communication port, adopting standard international MODBUS main circuit control.

【FLEXIBLE CONTROL】- Control mode: V/F control and vector control. Frequency setting mode: digital setting, analog setting, serial communication setting, PID setting and so on. Various control technique by both synchronization and non-synchronization, dynamically realize fast starting without changing brakes.

【POWERFUL PERFORMANCE】- With extremely strong anti-jamming capability; With low output ratting torque, low speed running ability; Internal simple PLC, 6 multifunction input terminals, to achieve operation, zero speed, calculator, external exception program instructions and alarm; Auto voltage regulation (AVR) technique, for ensuring the inverter load capability.

【SAFETY PROTECTION】- Adopts overload protection, fuse protection, over-voltage (DC voltage>800V) or under-voltage (DC voltage<400V) protection, restart protection, stall protection, short-circuit protection and over-heat protection.

【WIDE APPLICATION】- Used for constant torque loads (such as hard starting: Air compressor, HVAC units) and variable torque loads (such as pumps, fans, etc.).
