Agilent/Keysight N8958A Autoranging System DC Power Supply 1500V 40A

The Keysight N8900 Series Autoranging System DC Power Supplies, designed for demanding Automated Test Equipment (ATE) applications, offer flexible and programmable DC power with high performance and affordability. These power supplies feature autoranging capabilities, providing a wide range of voltage and current combinations at full power, effectively consolidating the functionality of multiple traditional power supplies into a single unit. This series is engineered for system integrators, labs, and enterprises requiring robust power solutions for testing and research. The N8900 Series is characterized by its stable output power, integrated voltage and current measurement, and a compact 3U design for efficient rack space utilization. For applications requiring higher power outputs, multiple N8900 units can be paralleled using the built-in master/slave control, enabling them to operate as a single power supply exceeding 100 kW without individual programming of each unit. Connectivity is facilitated through standard GPIB, Ethernet/LAN, USB 2.0, and analog interfaces, ensuring compatibility with existing and future test system architectures, and compliance with the LXI Core specification. The integrated web server further enhances control by allowing remote access and operation via a standard web browser.

### Technical Specifications

**N8900 Series Power Supplies**

* **Output Response Time (Voltage Excursion 10% to 90%):**
* Up, full load: ≤ 30 ms.
* Down, full load: ≤ 80 ms.
* Down, no load: ≤ 10 s.
* **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. Specifications are detailed in model-specific datasheets.
* **Command Response Time:** Specific values are detailed in model-specific datasheets.
* **Remote Sense Compensation:** Values are provided per voltage range (e.g., 2 V, 5 V, 10 V, 18 V).

**Interfaces**

* **Standard I/O:** GPIB, Ethernet/LAN, USB 2.0, and Analog interfaces are included as standard.
* **LXI Compliance:** Fully compliant with the LXI Core specification.

**Physical and Environmental**

* **Rack Mount Kit (N8958A):**
* Designed to rack mount one N8900 Series DC Power Supply in 3U of rack space.
* Specifically for use in Keysight racks; may require modification or may not be compatible with non-Keysight cabinets due to rack column features.
* Includes necessary supports that replace standard rack rails or slides, as standard rails are not compatible due to instrument width.
* Installation typically requires Torx T20 and Phillips head drivers.
* **Rack Height:** 3U.
* **Operating Temperature:** Warranted over the ambient temperature range of 0°C to 45°C after a 30-minute warm-up period.

**Compatibility**

* The N8958A Rack Mount Kit is compatible with all 28 models within the Keysight N8900 Autoranging System DC Power Supply series.
* Line cords and terminations are not included and must be supplied by the user based on local laws and codes.
