Pursuit of Growth,
Ever-Lasting Operation
Our company was established on May 1988. In the
beginning, OEM is our main products. Owing to stick to the
best quality and service as our policy in business, our pro-
ducts have been trusted and praised from our customers.
Building our own brand name is our main goal of pro-
motion. Through the consistent Development and improve-
ment, we put Bridge Rectifiers which obtained the approval
of UL in the United States into the market in 1993. Our pro-
ducts in the market have met the international standard.
In view of the future development, we manufacture
Bridge Rectifiers with our expertise and versatility. In this
way we may march to the way of international sales which
is our goal of consistent pursuit.
