The RSP300-168 from Recom Power is a Surge Protector that is ideal for clamping RIA12 and NF F01-510 standard voltage transient applications. This surge suppressor requires an input voltage of 40 - 160 V and has a power rating of 300 W. It has been designed to protect DC/DC converters from railway over-voltage transients up to 385 V (DC). This protector tracks the input voltage and clamps the output voltage to 168 V (DC). It can be inserted in series with the input of the RP180H-110xxSRW, RPA200H-110xxSRUW, and RP240H-110xxSRW converter families to make them compliant with both RIA12 and NF F 01-510 surge immunity specifications. This RoHS-compliant surge protector is available in a PCB-mount package that measures 40.6 x 25.4 x 10.2 mm.
