Introducing the OSA 5405-P substation grandmaster for smart grid timing

Our OSA 5405-P substation grandmaster delivers the precise and reliable timing that utilities need to leverage new smart grid applications, including intelligent power generation, distribution and control systems. Available with rack, DIN rail and wall mounting options, this ultra-compact synchronization solution reduces cost and complexity in timing networks. The OSA 5405-P also protects mission-critical infrastructure from the risk of GNSS outages with accurate PTP grandmaster clocks and network-delivered timing.

You should be scared!
