Feature: The product 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 has quick start-stop response and high low speed torsion. 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). The maximum output frequency of the converter is 0-400 Hz. Frequency converter with multi-function relay transmission, PID function, constant pressure water supply function. Inverter built-in temperature detection, internal self-cooling function for the external environment requirements are low. The additional control panel is equipped with 1 meter long connecting wire.
