Applications / YDS was established in 1990 at Tainan, Taiwan and our factory Ho Mao electronics was established in 1995 at Xiamen, China. We are the leading electronic manufacturer with ISO 9001 & ISO 14001 certified.

Medical Application

◆ DC-DC Converter
Yuan Dean has accumulated years of experience and dedicated to power supplies research and development, and this year launched the medical class DC-DC converters to respond the rigorous application of medical equipment and reinforced insulation system. Yuan Dean offer 1 to 10W DC-DC converters that meet the medical certification and have high isolation withstand voltage. As we understand the requirements formedical application and we have increased insulation isolation from 3000VAC to 5000VAC. Our medical DC-DC converters meet the ANSI/AAMI ES60601-1, IEC/EN 60601-1 3rd edition of medical safety standards and widely used in medical assist devices, computed tomography, ultrasound and other medical ancillary equipment. We proudly recommend 30DW-10WM for the SIP 7 package which can reach 10W, 3000VAC.

◆ AC-DC Converter
AC-DC converter (medical) is one of Yuan Dean's major product, feature with universal input 85-264VAC and meet the safety standard. We have high isolation with 4KVac, new GA5M & GB5M series, which has both module and open frame choices.

Railway Application

◆ DC-DC Converter

Yuan Dean Railway DC-DC Converter series get the power range from 8 to 40W, our layout is able to meet stringent requirements and harsh environment testing to satisfies the needs of railway application. The input voltage is from 40 to 160Vwhich means it meets the normally power using demands (24V/48V/72V/110V), and has many protectionmechanisms (over-current protection, output over-voltage, output short-circuit protection), can be extensively usedin the railway traction inverter, standby power system, train operation monitoring, gate controller ... and many other railway systems.
