The Keysight N8931A is a 15 kW autoranging, single-output programmable DC power supply designed for automated test equipment (ATE) applications. Its key feature is the autoranging output, which provides a wide range of voltage and current combinations at full power, unlike traditional power supplies with a fixed output characteristic. This flexibility allows a single N8931A unit to perform the function of multiple power supplies, offering significant space and cost savings. The N8931A is part of the N8900 Series, which offers power supplies in 5 kW, 10 kW, and 15 kW configurations.
### Technical Specifications
**Electrical Output Ratings:**
* **Maximum Output Power:** 15000 W
* **Maximum Output Voltage:** 80 V
* **Maximum Output Current:** 510 A
* **Output Voltage Range:** 0 to 80 V
* **Output Current Range:** 0 to 510 A
**Input Power:**
* **Input Voltage:** 208 VAC (187 – 240 VAC)

**Autoranging Capability:**
* The autoranging output provides flexibility by offering various voltage and current combinations at full power. This differs from traditional power supplies that deliver full power at only one voltage and current combination.
* Examples of possible combinations include:
* 80 V @ 187.5 A for 15000 W
* 29.4 V @ 510 A for 15000 W
**Expandability:**
* Units can be easily paralleled to create a single power supply with a total output power exceeding 100 kW.
* The built-in parallel link allows for programming as if it were a single large power supply, eliminating the need to program each unit individually.
* Up to ten identical units (same model number) can be operated in parallel.
**Measurement and Monitoring:**
* Built-in voltage and current measurement capabilities.
* Ability to monitor measured output voltage and current via an analog voltage signal (0-5 V or 0-10 V) corresponding to 0-100% of full-scale.

* Software allows tracking and recording of power supply output for specific events.
* Cloud connectivity for controlling power supplies.
* Data export to tools such as MATLAB, Microsoft Excel, or Word.
* Automated test sequences can be created quickly with minimal instrument knowledge.
* Offers IVI-COM drivers for simplified system development.
* Output voltage and current can be programmed via an analog voltage signal (0-5 V or 0-10 V).
**Additional Information:**
* Line cords or terminations are not included.
* Available in configurations for 208 VAC or 400 VAC input to utilize existing AC wiring.
* The N8900 Series includes models with various voltage and current combinations, with a total of 28 models available across 5 kW, 10 kW, and 15 kW power levels.
