Keysight Technologies Inc. has introduced a rack system for high-power DC applications. The prewired N8900 Series rack system reduces system complexity and saves time for engineers designing and implementing high-power systems for challenging applications requiring up to 90 kW.
When engineers design high-power racks, they face system design, debugging and safety challenges associated with high voltages. The N8900 Series rack system helps engineers easily overcome these challenges for voltages up to 1,500 V and currents up to 3,060 A, allowing them to focus on their core business objectives.
The new rack system allows users to install up to six 15-kW N8900 Series autoranging DC power supplies in a parallel configuration that can deliver up to 90 kW and up to 3,060 A. Autoranging capability allows customers to get full-power output at a wide range of voltages.
The rack system’s internal communications wiring allows users to treat the entire rack as a single power supply that delivers up to 90 kW. Engineers can communicate with the rack through one master power supply with communications to the individual power supplies being handled within the rack. Users can communicate with the N8900 Series rack system via LAN (LXI Core), USB, or GPIB interfaces, all of which come standard with the system.
“Many high-power applications extend well beyond 15 kW, and creating a power supply system to deliver high power can be time consuming,” said Kari Fauber, general manager of Keysight’s Power and Energy Division. “The N8900 rack system allows customers to quickly, easily and safely configure N8900 Series power supplies in parallel to achieve up to 90 kW.”
The N8900 Series rack system can be ordered now. N8900 Series 15-kW power supplies must be ordered separately. Starting prices range from $17,500 to $18,500. The 400-VAC rack models will begin shipping in February and the 208-VAC rack models will begin shipping in mid-2015.
