The Advanced Telecom Computing Architecture (AdvancedTCA or ATCA) is an open source, multiple vendor architecture for carrier grade communication equipment. Carrier grade systems and software are rigorously tested to ensure a level of uptime (system availability) that is higher than normal.

A manufacturer of ATCA, known for their time-to-market development speed, asked TDK-Lambda for a solution to their redundant power supply requirement. The HFE2500-48/S was suggested, with each unit offering 48V at 2500W and an I²C communications bus, along with the HFE 1U high rack which can hold up to four units. TDK-Lambda’s reputation for quality was well known to the customer, but the final decision driver was availability.  This was met utilising the local factory and warehouse inventory.
