Agilent N8900 Series Autoranging System DC Power Supplies N8920A-N8924A (5 kW, 208 VAC) N8925A-N8930A (10 kW, 208 VAC) N8931A-N8937A (15 kW, 208 VAC) N8940A-N8944A (5 kW, 400 VAC) N8945A-N8950A (10 kW, 400 VAC) N8951A-N8957A (15 kW, 400 VAC) Data Sheet • Autoranging output – does the job of multiple power supplies! • 5, 10, and 15 kW maximum output power • Up to 1500 V and up to 510 A • 14 different voltage, current, and power combinations available in 208 or 400 VAC (28 total models) • Just the right amount of performance at just the right price • Easily parallel units to create “one” power supply with > 100 kW of power • Built-in voltage and current measurement Family of Affordable, Autoranging System DC Power Supplies The Agilent Technologies N8900 Series provides 5, 10, and 15 kW autoranging, single-output programmable DC power for ATE applications that require just the right amount of performance at just the right price. The N8900 Series power supplies’ autoranging output characteristic enables unprecedented flexibility by offering a wide range of voltage and current combinations at full power. Power supplies with “rectangular,” or traditional, output characteristics provide full power at only one voltage and current combination. Just one N8900 does the job of multiple power supplies. It’s like having many power supplies in one! The N8900 Series provides stable output power, built-in voltage and current measurements, and autoranging output voltage and current from 80 to 1500 V and 10 to 510 A. These supplies offer many system-ready features like multiple standard I/O interfaces to simplify and accelerate test-system development and compact 3U design to save rack space. If more power is required, easily parallel multiple N8900 units to create “one” power supply with > 100 kW of total output power. The builtin master/slave control enables programming as if it’s just one big power supply; no need to program each supply individually. • High power density, 15 kW in only 3U (5.25 inch/13.34 cm) • Protection from over-voltage, over-current, and overtemperature • LAN (LXI Core), USB, GPIB, and analog interfaces all standard Autoranging output – like having many power supplies in one!

Autoranging output – does the job of multiple power supplies The N8900 power supplies’ autoranging output characteristic makes it much more flexible than rectangular, or traditional, output characteristic power supplies because they expand the power curve, giving the user more voltage and current combinations in one power supply. It’s like having many rectangular power supplies in one. For example, the 1000 V, 30 A, 10 kW model is capable of 1000 V and 10 A at 10 kW as well as 333.3 V and 30 A at 10 kW. If it were a rectangular output, the specifications would be 1000 V, 10 A, 10 kW. At...

Simplify system connections The N8900 Series power supplies comes standard with GPIB, Ethernet/LAN, USB 2.0, and analog interfaces giving you the flexibility to use your I/O interface of choice today and safeguard your test setup for the future. There is no need to worry whether or not you are choosing the right interface when they all come standard. The N8900 is fully compliant with the LXI Core specification. Remote access and control The built-in Web server provides remote access and control of the instrument via a standard browser. This control goes above and beyond the LXI...

Options None AC input voltages If the AC input voltage where the power supply will be used is: • 187 to 229, please choose a 208 VAC model (N8920A-N8937A) • 360 to 440 VAC, please choose a 400 VAC model (N8940A-N8957A) Rack mount kit for Agilent racks (coming soon) Use standard rack rails for non-Agilent racks. Line cords and terminations (plugs) Due to the number of different line cords and terminations around the world, the N8900 power supplies do not come with line cords or terminations. Users will need to supply their own dependent on the local laws and codes of the country/region where...
