Electrical service conditionsTo overcome the severity and provide the stable services in railway applications, EN50155 also definesseveral standards for electrical service conditions such as input voltage range, input voltage ripple, andinput surges. Each category follows clear requirement. For example, the requirements of input voltage arelisted below:Input Voltage RequirementsNominal Input Permanent inputvoltage rangeBrownout 100ms(0.6xVnom)Transient 1s(1.4xVnom)24VDC 16.8 -30.0V 14.4V 33.6V37.5VDC 26.2 -47.0V 22.5V 52.5V48VDC 33.6 -60.0V 28.8V 67.2V72VDC 50.4 -90.0V 43.2V 100.8V96VDC 67.2 -120.0V 57.6V 134.4V110VDC 77.0 -137.5V 66.0V 154.0VElectromagnetic compatibility (EMC) is another main category of EN50155 standard. The equipment shouldbe protected in order not to be negatively affected by conducted or radiated interference, which is referredto EN 50121-3-2 and should not emit radio frequency interference (RFI) that excess the level defined inEN 50121-3-2.EN50155EN50155 series models provide IP-67 protection and M12 connectors with wide operating temperaturefrom -40°C to 75°C for harsh operating environment in railway applications. The rugged and durableswitches have long MTBF that ensure the network quality of video entertainment service and high qualityvideo surveillance at the same time with Giga fiber ports. Besides hardware specifications, the powerfulsoftware features also ensure the management convenience. A well-design switches security functions areessential to securing modern Ethernet network.EN50155 Product List:IES-0005-M12 IES-0008-M12 IPES-0008-4-M12 IES-2008-67 IPES-2208GF-67 IPES-2208-M12P24
