The product can be connected with an external controller to realize 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 .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 (short-circuit protection).The maximum output frequency of the converter is 0-400 Hz.Frequency converter with multi-function relay transmission, 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 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 . 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.Specification:Name: Variable Frequency InverterColor: BlackAdapt motor power: 2.2kW Scope of application: UniversalRated current: 20 (A)Rated input voltage: Single-phase AC 220 VPower output phase: three phaseSupply voltage: Low VoltageFilter: NoControl mode: V/F open loopOutput voltage regulation: PWM controlColour:blackMaterial:Plastic + metalSize:about 160*120*95mmPackage Contents:1 * Variable Frequency Drive InverterOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
