1、[Multiple Protections] With soft start and stop function, protections of phase loss, constant torsion, load loss, overload, overcurrent, short circuit, overvoltage, undervoltage, overheat and stall, the VFD is very safe to use. 2、[Reliable Materials] Industrial flame retardant ABS shell is impact and heat resistant, has a good comprehensive performance. All internal components adopt patch design, greatly increase the stability of the machine. 3、[Easy to Use] Humanized keyboard and digital display screen make the frequency inverter easier to operate. Unique design ensures strong heat dissipation performance and longer life. 4、[Three Proof Paint Surface] Reduce the adhesion thickness of the paint surface, and the impact of oil dirt and dust on the chip, ensure the reliability in harsh environment. 5、[RS485 Interface] Standard communication protocol, users can read and write functional parameters, read status parameters, write control commands, etc. through upper computer. The converter is in the slave mode during communication.
