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 torque.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 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 mission, PID function, constant pressure watersupply function. Inverter built-in temperature detection, internal self-cooling function for the external environment requirements are low.The additional control panel is equipped with external fixed casing support and 1 meter long connecting wire. This is a kind of fine quality variable frequency inverter, which 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 torque. The internal protection function of the product has such protection functions as under-voltage, over-voltage, over-current, over-heat, etc. You can have a try.
