The Power Express family of Class 2 Distribution shelves provide 100VA limited circuits for safe powering of remote loads. Their NEC Class 2 rating allows for power cabling to be deployed in a data cable raceway instead of conduit, reducing labor time and increasing speed to market. Each shelf is designed to support an alarm card for stand-alone deployment and can be uplinked over the RS-485 data bus through the RJ-45 connection on the rear of the shelf. This uplink allows each shelf to interface with a Pulsar Plus controller (commonly used in our Infinity power systems), allowing local access, alarming and control of each circuit in every shelf – as well as remote interface over the controller LAN connection. Shelf configurations include a 32-circuit limiter shelf, a 32-circuit extended reach shelf with integrated voltage boost, and a 16-circuit shelf with an integrated rectifier.
