KE300A-04 Series Single-Phase Motor Inverter

Name: KE300A-04 Series Single-Phase Motor Inverter
Brand: Shenzhen MICNO Electric Co., Ltd.

KE300A-04 single-phase motor series special inverter, based on the world's leading speed sensorless high-performance vector core control algorithm, combined with the unique start-up and control requirements of single-phase motor, using a new magnetic flux vector control technology to achieve true The two-phase orthogonal 90-degree magnetic flux vector control can be used without removing the capacitor.

This series of products has the characteristics of large starting torque and high efficiency of the whole machine, and has added some special functions of single-phase motors (such as current suppression, voltage suppression, jitter suppression, etc.)

The user does not need to make too many complicated settings when using it, but only needs to make simple parameter modification according to the actual use site.

It can be widely used in fan, water pump, power tool and other single-phase asynchronous motor drive applications.

Features of KE300A-04 Series Single-Phase Motor Inverter

(1) It is specially tailored for single-phase asynchronous motor. It is easy to install and debug, and the motor is not used for any modification to achieve stepless speed regulation.

(2) DSP high-speed control core

The control core adopts the high-speed digital processor DSP produced by TI (Texas Instruments).

(3) High starting torque and fast dynamic response

(4) Low motor noise and low temperature rise

(5) Strong instantaneous overcurrent capability

(6) Non-stop function when instantaneous power failure

(7) Robust EMC design

(8) Modular design, very flexible configuration

(9) Excellent robust performance can ensure that the load can start and stop quickly;

(10) Fast current limit function can quickly limit the current within the protection point, reducing the probability of frequent overcurrent alarm failure.

(11) High power factor output

(12) The built-in PID regulator can easily form a closed-loop control system for process quantities such as temperature, pressure, and flow.

(13) Adopt advanced power module drive mode, which can effectively suppress harmonics and eliminate interference to peripheral control loops and sensors during inverter operation.

(14) Perfect protection functions include overvoltage / undervoltage protection, overheat protection, ground fault protection, short circuit protection, overcurrent protection, overload protection, etc.
