385 VDC Surge Protectors for Railway Converters from Recom

14 June 2018

Recom has added the RSP-168 surge protectors to their portfolio, which allow DC/DC converters to meet both Source: RecomSource: RecomRIA12 and NF F 01-510 surge immunity specifications for railway applications. Three versions cover the wide range of RECOM’s railway certified DC/DC converters from 20 W up to 240 W.

The RSPxxx-168 are surge protector modules designed to protect railway DC/DC converters from excessive voltage surges of up to 385 VDC. The output voltage tracks the input voltage up to 165 VDC, thereafter the output voltage is clamped to prevent damage to the converter from input over-voltage conditions that cannot normally be filtered out. There are three options available: the RSP20-168 is suitable for up to 20 W, the RSP150-168 for up to 150 W and the RSP300-168 for up to 300 W converters.

To achieve compliance with both the RIA12 and NF F 01-510 surge immunity specifications, these modules are simply connected in series with the input of the DC/DC converter. Samples and OEM pricing are available from all authorized distributors or directly from Recom.
