PSU – Compact new 330W AC/DC power supply targets PoE applications (XL330-54)Oct 26 2012 - Power [More Power Articles]
Power Sources Unlimited has announced the new XL330-54 AC/DC power supply with ‘unrivalled’ power density and ultra-high efficiency from a very small footprint. The unit is seen as the ideal solution for Power-over-Ethernet (PoE) applications.
The 34.3mm high open-frame XL330-54 has a 76mm x 135mm footprint that delivers a power density of 15W/in³ with only 13CFM cooling, a space savings of 32% compared to typical 1U units of similar rating. 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 less heat than most comparable power supplies minimizing cooling requirements and improving system reliability.
The XL330–54 has two primary outputs: 54V/6.1A and 12V/9A, plus a 12V/1A auxiliary output. Other key features include universal AC input (90–264VAC) and active inrush current protection of 10.5A at 240VAC, which does not change during operation, SCP, OVP and OPP. RoHS compliant and meets all major international safety and EMC requirements, says the company.Electropages - Electronics Components News, From Leading Electronics Distributors. More news from PSU
