Viper-212-T3G是一种管理型12端口路由交换机,专为满足轨道车辆市场的所有需求设计。该型号配有极其紧凑且坚固的外壳,适用于狭小空间和恶劣环境。威斯特摩
WeOS操作系统支持广泛的IP网络标准,允许建立灵活的弹性网络,满足轨道市场的需求。
如同安装在轨道车辆上的所有设备一样,Viper已经按照EN 50155定义的标准要求通过了全面的测试。
威斯特摩深刻理解应用于轨道车辆系统上的设备,必须满足EN 50155标准,使用寿命至少20年。因此除了使用最高质量的料件来实现更长的MTBF,而且还采用了GORE-TEX®透气防水薄膜材料来防止凝露,使IP67防护等级的外壳具备更高防水能力。由于铁路行业的高振动环境,我们还在Viper外壳设计上,选用了整体式螺纹的M12连接器,确保产品在整个使用寿命内始终保持IP67防护等级。
EN 50155标准要求通过强制性的性能和电气隔离测试。威斯特摩不仅满足这些要求,而且还满足制造商对列车控制的额外要求。威斯特摩的瑞典工厂为轨道车辆市场制造以太网交换机已经多年,完全了解如何提供最优化的制造解决方案。
Viper可满足轨道车辆环境的要求,非常适合用于所有严苛工作条件和极端环境的应用。
