ENCLOSURES
each building block is designed for flexibility. As an example, they have engineered their chassis to accommodate standard power supplies. PXIe supports many different voltages, and it is unlikely to be able to find a commercially available power supply that can fulfil them all. Instead of using a dedicated power supply with all the required output voltages. nVent has opted for a single 12-volt output, which is available from many different vendors. To accommodate the standard power supply, nVent SCHROFF’s chassis are built with a specially designed power distribution board to provide any additional voltages as required.
nVent SCHROFF has also implemented flexible switching designs. Currently, their chassis are based on a PXI Gen 3 switch design. Like many companies, they have dealt with a great number of shortages over the last few years. While Gen 3 switches were unavailable nVent SCHROFF to communicated with customers in a timely manner to understand their design constraints and implement a shift to Gen 2 switches, which most of the market can accommodate. They have also used PCIe switch ball grid arrays (BGAs) from different vendors to design switch modules, providing them with an alternative solution if faced with procurement or

allocation challenges.
When assessing a vendor, it is essential to understand how much production happens in-house. For example, nVent SCHROFF’s printed circuit boards (PCBs) are designed, assembled, tested, and integrated in-house, so there’s no third-party involvement for integration or assembly. This translates to shorter lead-times and less reliance on third-party suppliers. With the engineering department located directly above the production floor, they are always on-hand to support custom projects with no delay. A rapidly evolving T&M environment provides opportunities for suppliers to become partners. With open standards there’s always a second source to draw from and valid design trade-offs to pursue.
“nVent SCHROFF have the know-how to mitigate issues and lessen the cost of failures and shortages for customers because they have great expertise in modularity. They know what building blocks and customisations work best because they have a complete overview of the market and supply chain. Leveraging this expertise helps customers limit rescoping and eliminate total redesigns in the face of supply chain shortages,” comments Dave Martin, Director of Business Development at Foremost Electronics.
