June 25, 2020
TDK Corporation (President and CEO: Shigenao Ishiguro) announces a new developed
reliable DC-DC Converters, TDK-Lambda brand RDS-A（30/60/100/180W）Series. TDKLambda Corporation (President and CEO: Hiroyuki Yashiro) will start mass production andshipment from July 2020(30/60W) and from October 2020 (100W/180W).
While current, chassis mounted DC-DC Converters RDS series will continue to be available,
we have developed the RDS-A series, with improvement in characteristics.
The mounting hole position and terminal block shape will be compatible to the current RDS
series. Easy product service/maintenance and long term used is possible.
The RDS-A series uses the latest materials and optimizes the circuit configuration to improve
efficiency by up to 6% compared to the current product (180W product, 24VDC output).
Coatings on both sides of the component mounting board have been implemented to further
improve reliability.
The railway is seen as energy-saving and low-carbon means of transportation globally.
With the release of this new RDS-A series, we can offer line up of new products to contributethe creation of a safe and environmentally friendly transportation infrastructures.
