RECOM RSPxxx-168 surge protectors for railway converters

RECOM has added the RSP-168 surge protectors to its portfolio, allowing DC/DC converters to meet both RIA12 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 to 240 W.

The RSPxxx-168 surge protector modules are 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 overvoltage 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 compliancy 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.
