Achieved through synchronous rectification, Or-ing MOSFETs, and a unique active power factor correction (PFC) design, the XL330-54’s 90% maximum full-load efficiency yields 23% less heat than most comparable power supplies, minimising cooling requirements and increasing system reliability.
The XL330-54 has two primary outputs, 54 V/6.1 A and 12 V/9 A, plus a 12-V/1-A auxiliary output. The 54-V output is 2250 V dc isolated from the other outputs, making it compatible with Power-over-Ethernet (PoE). The design also allows active current sharing on the 54-V output for up to four power supplies to be operated in parallel. N+1 operation can be configured as well.
Other features include universal ac input (90 264 V ac) and active inrush current protection of 10.5 A at 240 V ac, which does not change during operation.
