Power-One Inc. (Camarillo, CA) introduced its 3,000 W NHC3011-6 ac-dc power supply, which provides up to 107 A of 28 Vdc, from an input of 180 Vac to 264 Vac, with no de-rating for up to 50 °C. A mean time between failure in excess of 700,000 hours makes the NHC3011-6 suitable for RF amplifiers, lasers and other high-reliability industrial applications.
The 3U-high NHC3011-6 power supply features no minimum-load operation, active-current sharing, EN61000-3-2 compliant power-factor correction and LED output current-monitoring indicators. Interface signals include input power-fail warning, remote-sense, remote on/off, remote voltage adjust, output-good and current monitoring. Protection features include over-voltage, over-current and over-temperature.
The NHC3011-6 provides a power density of approximately 10 W/in³ from a 5 in x 5 in x 12.25 in (127 mm x 127 mm x 311 mm) overall package size. Input connections are via terminal block and copper bus bar blades, with tapped screw holes provided for output connections.
Pricing for the NHC3011-6 is $1,500 each in quantities of 10 to 24. Evaluation units are usually available in six to eight weeks. Production quantities are typically available in 8 to 10 weeks.
