The 1.35-inch high, open-frame XL330-54 has a 3-inch x 5.3-inch (76 mm x 135 mm) footprint to deliver a power density of 15W/in3 with only 13CFM cooling, a space saving of 32% compared to typical 1U units of similar rating, most of which have a 6-inch x 4-inch (102 mm x 152 mm) footprint. Its maximum full-load efficiency of 90%, achieved through synchronous rectification, Or-ing MOSFETs and a unique active PFC design, means that the XL330-54 generates 23% less heat than most comparable power supplies, minimizing cooling requirements and increasing system reliability. The high efficiency delivers energy savings throughout the product’s life, providing greater return on investment.
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 VDC isolated from the other outputs making it Power-over-Ethernet (PoE) compatible. The design allows active current sharing on the 54 V output for up to four power supplies to be operated in parallel. N+1 operation can also be configured.
Other features of the power supplies include universal AC input (90-264 VAC) and active inrush current protection of 10.5 A at 240 VAC, which does not change during operation. The XL330-54 CS is RoHS compliant and meets all major international safety and EMC requirements.
