Power-One Inc. (Camarillo, CA) introduced a new 400 W, five-output, ac-dc power supply, the NET2-4350, which features a dual-converter topology that provides two high-current outputs. The two “main” outputs can be used independently as tightly-regulated voltages directly where they are needed, and/or as bus voltages for final conversion via point-of-load converters.
The 1U-high power supply operates from an input range of 85 Vac to 264 Vac to provide 3.3 V at 55 A, 5 V at 40 A, two outputs of 12 V at 5 A, and a 5.2 V at 2 A standby output. The first four outputs can current share with other power supplies in fault-tolerant-redundant configurations, making this a suitable power source for high-reliability applications.
Additional features include 7 W/in³ power density, no minimum load operation, EN61000-3-2 compliant power-factor correction, and load-transient response. Interface signals include input power-fail warning, remote sense on non-standby outputs, and output good. Protection features include over-voltage, over-current and over-temperature. The 8.25 in x 4.50 in x 1.59 in (209.6 mm x 114.3 mm x 40.4 mm) product incorporates an output terminal that allows connection to any combination of #8 ring lugs, 0.25 in quick disconnects, cable connectors, and PCB-mounted connectors. Agency approvals include UL 60950, CSA 60950 (UL/cUL) and EN60950-1 (TUV).
Pricing for the NET2 is $390 each in quantities of 100. Evaluation units are usually available in less than six to eight weeks. Production quantities are typically available in 8 to 10 weeks.
