Feature: 1. The external controller can input 0~5V/0~10V analog voltage input and 0~20mA current signal input to realize stepless speed control. 2. The inverter has a quick start and stop response. The low speed torsion is large. Immediately stop to protect the host from the short circuit (short circuit protection). 3. The internal protection functions include undervoltage, overvoltage, overcurrent, overheating, etc. The internal internal cooling function has low requirements for the external environment. 4. The maximum output frequency range of the inverter is 0.01~400Hz. 5. The inverter comes with multi-function relay transmission, PID function, constant pressure water supply function. 6. Inverter built-in temperature detection.
