The Keysight N8935A is a 15 kW autoranging DC power supply engineered for automated test equipment (ATE) applications requiring high-power, flexible voltage-current combinations. This single-output programmable supply delivers 0–750 V and 0–60 A at full 15,000 W capacity, eliminating the need for multiple discrete units across different operating points. Autoranging capability automatically selects optimal voltage and current settings, maintaining full power output across the entire operating envelope.
Technical Specifications

– Key Features
• Autoranging output maintains 15 kW across wide voltage-current operating range
• Standard interfaces: LAN (LXI Core), USB, GPIB, analog
• Parallel operation supported up to ten units for 100 kW total output
• Master/slave control architecture for synchronized multi-unit systems
• Single-supply programmability simplifies ATE integration and control logic
– Typical Applications
• High-power device characterization and functional testing
• Power conversion system validation (DC-DC, AC-DC topologies)
• Thermal and reliability stress testing under variable load conditions
• Battery simulation and charging profile development
• Aerospace, automotive, and industrial electronics ATE platforms
– Compatibility & Integration
The N8935A mounts in standard 19-inch racks using the optional Keysight N8958A Rack Mount Kit. Multi-unit systems integrate via LAN or GPIB for centralized control, enabling flexible power delivery architecture in modular ATE systems.
