PRODUCT OFFERING
Automated Assembly Line
Delta has been moving forward with continual product improvement. Our three-phase filters
with maximum amperes of 600A and voltage rating of up to 520 VAC are presently in mass
production, and have been used to a large extent in AC motor drives and machine tool
applications. In the meantime, development of high frequency products for telecom &
networking market are underway.
Our present products covers IEC inlet filters with a maximum of 20A, chassis mounting filters
with maximum of 60A and the three-phase filters. Thanks to our long experience working with
multi-national companies, we have the capability to deliver customized products within a
short period of time, whatever the quantity is. Our facilities, experience, services,
compounded with the latest technology are there to offer EMI filters to meet our customers'
utmost satisfaction.
