The Keysight N8945A is a high-power autoranging DC power supply designed for demanding automated test equipment (ATE) applications. It offers a significant power output with a flexible autoranging capability, allowing it to operate as multiple power supplies in one unit. This supply is part of the N8900 Series, which includes models with 5 kW, 10 kW, and 15 kW outputs, available in both 208 VAC and 400 VAC configurations. The N8945A specifically delivers up to 10 kW of power with an output voltage range of 0 to 80 V and an output current range of 0 to 340 A. Its autoranging feature provides a wide combination of voltage and current outputs at full power, distinguishing it from traditional “rectangular” output power supplies that offer full power at only one voltage/current setting.
### Technical Specifications
**DC Output Ratings:**
* **Voltage:** 0 to 80 V
* **Current:** 0 to 340 A
* **Power:** 10000 W (10 kW)
**AC Input:**
* **Voltage Range:** 360 – 440 VAC
* **Configurable Input:** Available in 208 VAC or 400 VAC models to utilize existing AC wiring
**Performance Characteristics:**
* **Autoranging Output:** Provides flexibility by delivering a wide range of voltage and current combinations at full power. This capability means one N8900 unit can replace multiple traditional power supplies.
* **Maximum Output Power:** Models within the N8900 Series offer 5 kW, 10 kW, and 15 kW maximum output power.
* **Extended Output Capabilities:** Can achieve output voltages up to 1500 V and source current as high as 510 A across the series.
**Programming and Measurement:**
* **Programmable:** Yes
* **Built-in Measurement:** Features integrated voltage and current measurement capabilities.
* **Programming Accuracy:**
* Voltage: 0.1% of full-scale
* Current: 0.2% of full-scale
* **Measurement Accuracy:** (Specific values not detailed in provided snippets, but accuracy is stated as a feature)
* **Load Effect:** (Change from 0% to 100% of full load)
* **Load Transient Recovery Time:** (Time for output voltage to recover within 1% of its rated output for a load change from 10% to 90% of its rated output current)
**Protection Features:**
* **Overvoltage Protection:** Yes
* **Overcurrent Protection:** Yes
* **Overtemperature Protection:** Yes
**Interfaces and Connectivity:**
* **Standard Interfaces:** LAN (LXI Core), USB, GPIB, and analog interfaces are all standard.
* **Analog Programming:** Output voltage and current can be programmed via analog voltage signals (0-5 V or 0-10 V) corresponding to 0-100% of full-scale.
**Physical and Environmental:**
* **Rack Space:** Compact 3U design saves rack space. High power density, e.g., 15 kW in only 3U (5.25 in / 13.34 cm).
* **Mounting Type:** Rack Mount.
**System Integration and Expandability:**
* **Parallel Operation:** Multiple N8900 units can be easily paralleled to create a single power supply with greater than 100 kW of total output power.
* **Master/Slave Control:** Built-in master/slave control allows programming as if it is one large power supply, eliminating the need to program each unit individually.
