Keysight (Agilent) N8925A Autoranging System DC Power Supply, 80 V, 340 A

The Keysight N8925A is an autoranging system DC power supply engineered for high-power ATE applications. It delivers up to 80 V and 340 A with a maximum output of 10 kW in a compact 3U rack-mountable form factor. Unlike traditional fixed-ratio power supplies, the N8925A's autoranging topology provides a continuous spectrum of voltage and current combinations at full 10 kW power - enabling a single unit to replace multiple conventional supplies and optimize test floor space and cost.

Technical Specifications

• Output Power: 10 kW maximum


• Voltage Range: 0 V to 80 V


• Current Range: 0 A to 340 A


• Input: 208 VAC nominal (187 VAC to 240 VAC range)

Key Features

• Autoranging output delivers full 10 kW across the entire voltage/current envelope. At maximum voltage (80 V), current reaches 125 A; at maximum current (340 A), voltage reaches 29.4 V.


• Wide AC input tolerance (187–240 VAC) accommodates international and variable facility power without de-rating.


• Integrated over-voltage, over-current, and over-temperature protection safeguards DUT and test infrastructure.


• Parallel operation of multiple units enables aggregate power exceeding 100 kW from a single logical source.

Compatibility & Integration

• Interfaces: GPIB, USB, LAN (LXI Core compliant), and analog control/monitoring


• Programmable and measurable through standard instrument protocols


• Multi-unit paralleling for scaled power delivery without adding control complexity
