Surge protector (voltage clamp) for FeaturFeatureses RIA12 and NF F01-510 transients Accessory Output follows input up to the clamp voltage bullet points (Productmanager) Clamping Max. load = 20W, 150W or 300W Surge -40C to + 95C Operating temperature Chokes Board-mount module RSPxxx-168 Protector Description 20W-300W, The RSPxxx-168 is a surge protector module designed to protect DC/DC converters from railway 168V over-voltage transients up to 385VDC. The output voltage tracks the input voltage in the range of 40-165VDC, thereafter the output voltage is Clamping clamped to 168VDC. Surge Protector The RSP20-168 is a DIP24 module that can be simply inserted in series with the input of the RP08-110xxSAW, RP08-110xxDAW, RP20-110xxSFR and RP20-110xxDFR converter families to make them compliant to both RIA12 and NF F 01-510 surge immunity specifications. The RSP150-168 is a board-mount module that can be simply inserted in series with the input of the RP40-110xxSFR, RP40Q-110xxSRUW, RP60Q-110xxSRUW, RP75H-110xxSRW, RP90Q-110xxSRW, RPA100H-110xxSRUW, RPA120H-110xxSRW and RP120Q-110xxSRW converter families to make them compliant to both RIA12 and NF F 01-510 surge immunity specifications. The RSP300-168 is a board-mount module that can be simply inserted in series with the input of the RP180H-110xxSRW, RPA200H-110xxSRUW and RP240H-110xxSRW converter families to make them compliant to both RIA12 and NF F 01-510 surge immunity specifications.
