The Variable Frequency Drive can be connected with an external controller to realize infinite speed regulation control by 0 ~ 5v/0 ~ 10V analog voltage input and 0 ~ 20mA current signal input. Frequency converter with multi-function relay transmission, PID function, constant pressure water supply function and built-in temperature detection, internal self-cooling function for the external environment requirements are low. The internal protection function of the product has such protection functions as under-voltage, over-voltage, over-current, over-heat, etc. When short-circuit occurs, it will stop immediately to protect the host (short-circuit protection).
