An overview of the

WLT - 02 type microcomputer excitation device USES Germany Siemens PLC (programmable controller) of high reliability and powerful function and application in the excitation system of new-style microcomputer excitation device. Regulator operating interface for Chinese touch screen, operation is extremely simple and intuitive. Based on PLC powerful network function at the same time, easy to realize with computer monitoring and control system.

WLT - 02 type microcomputer excitation device with excitation standards required by all of the features, performance indicators have reached or exceed standard requirements. Suitable for all kinds of small and medium-sized synchronous generator excitation system.
