Keysight 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 02 | Keysight | N8900 Series Autoranging System DC Power Supplies - Data Sheet Family of Affordable, Autoranging System DC Power Supplies The Keysight 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 lexibility 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 20 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 built-in master/slave control enables programming as if it's just one big power supply; no need to program each supply individually. Autoranging output - does the job of multiple power supplies The N8900 power supplies' autoranging output characteristic makes it much more lexible 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 speciications would be 1000 V, 10 A, 10 kW. At 333.3 V it would only be able to output 3.3 kW, not the 10 kW of an autoranging output. Figures 1 and 2 show a graphical representation of this example. - 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 - High power density, 15 kW in only 3U (5.25 inch/13.34 cm) - Protection from over-voltage, overcurrent, and over-temperature - LAN (LXI Core), USB, GPIB, and analog interfaces all standard Voltage 1000 V 10 kW power curve Autoranging output - like having many power supplies in one! 333.3 V 10 A 30 A Current Figure 1.

Rectangular output characteristic 03 | Keysight | N8900 Series Autoranging System DC Power Supplies - Data Sheet Easy front-panel operation Using the front panel controls, you have complete access to all of the N8900 features via the extensive menu system. You can either use the voltage and current knobs or enter your settings via the keypad. You can also set protection settings, power-on states, and other features. The output voltage, current, and power can be displayed simultaneously, and annunciators at the bottom of the display show power supply status and operating modes. You can lock the front panel controls to protect against accidental power-supply parameter changes. Device protection To safeguard your device, the N8900 Series power supplies provide over-temperature, over-current and over-voltage protection to shut down the power supply output when a fault condition occurs. Simplify system connections The N8900 Series power supplies comes standard with GPIB, Ethernet/LAN, USB 2.0, and analog interfaces giving you the lexibility 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 speciication. 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 speciication, giving users the ability to monitor and control the instrument from anywhere. Using the Web browser, you can set up, monitor and operate the N8900 remotely. Figure 3. N8900 Series web graphical user interface for remote access and control of the power supply Easy system integration and coniguration To simplify system development, the N8900 comes standard with IVI-COM drivers. The N8900 supports the easy-to-use SCPI (Standard Commands for Programmable Instruments). Parallel operation for more power Need more power, we've got you covered. Quickly create a master/slave setup for even more total output power. The N8900 Series power supplies give you the lexibility to easily connect in parallel up to ten identical units (same model number) for greater output current. The units can also be conigured to look like "one" big power supply. (See Figure 4, page 4.) Series operation is not recommended. 04 | Keysight | N8900 Series Autoranging System DC Power Supplies - Data Sheet Analog programming and monitoring The output voltage and current can be programmed from zero to full-scale by an analog voltage signal from 0 to 5 V or 0 to 10 V. Each corresponding to 0 to 100% of full-scale. The measured output voltage and current can also be monitored in the same way. AC input The N8900 has 28 total models. Fourteen have 208 VAC inputs and the remaining 14 have 400 VAC inputs. This gives the N8900 the ability to be used anywhere in the world. Choose 208 VAC for regions such as the Americas and Japan or choose 400 VAC for regions such as Europe and Asia.
