l         Introduction

The intermediate-frequency brushless alternator is extremely competitive because of the high difficulty in design and manufacturing and the exiguous supplier sources in the world. Most of the products are our unique and innovative designs, carrying lots of national patents and international approvals. All the products are manufactured in an environment certified by ISO9001 and ISO14001, and conform to IEC60034 and ISO6858 standards.
