240W DIN Rail DC-DCs meet Railway and ITE Safety Standards

July 30, 2018 by Paul Shepard

Mean Well has announced the DDR-240 series (240W) to enable DIN Rail dc-dc integration into higher power applications. Since the DDR-240 series is designed to meet both railway and ITE safety standards, it is suitable for dc-dc applications such as industrial and railway control, security control, and communication systems.

The DDR-240 series has ultra-slim enclosure design with a width dimension of only 40mm. This enables convenient installation onto TS-35/7.5 or 15 standard DIN rails without having to worry about spacing.

The product design also includes outstanding features such as 2:1 wide input range, 4000Vdc I/O isolation, -40 to +70°C operating temperature range, 150% peak load capability, current sharing up to 960W (3+1), and 5G anti-vibration capability.

In addition, the DDR-240 series is certified to the ITE IEC62368-1/EN55032, EAC TP TC004, as well as EN50155 railway safety standards, ensuring the DDR-240 can perform reliably as additional system insulation, dc UPS, battery voltage regulator, etc. in all fields of ITE and railway applications.
