Overview
The series of microcomputer excitation devices for synchronous motors are used for synchronous motors (~)
Single-machine matching with constant excitation objects, such as driving various types of compressors, ball mills, blowers, water pumps, refrigerators and other non-impact loads Synchronous electric motor site.
Performance features
Dual excitation
The device can double excite according to rotor slip and timing, and automatically activate in strict accordance with the principle of forward polarity excitation.
Double demagnetization
Double demagnetization, no adjustment required, low voltage demagnetization when the synchronous machine is started, no pulse vibration at startup.
Complete protection
Complete protection functions, including out-of-step protection, phase loss protection and fault recording functions.
Digital setting
The control part adopts a high-performance microcomputer controller structure, without potentiometer, fully automatic adjustment, easy and convenient installation, debugging and maintenance, and stable and reliable operation.
Digital adjustment
Use digital keys to adjust the excitation voltage and current, and the adjustment process is smooth.
Strong anti-interference
The microcomputer controller adopts high-performance industrial control chip, making the device stable and reliable. The input sampling and output driving signals are optically isolated, which enhances the anti-interference ability of the whole machine.
Intuitive display
, Chinese LCD display, large touch screen (optional). Chinese menu, data display is intuitive and clear, and the amount of information is large.
Complete communications
Equipped with standard
,
bus interfaces to realize remote communication (optional).
