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
• Output: 0–750 V, 0–60 A, 15 kW maximum

• AC Input: 187–240 VAC, 3-phase at 208 VAC
• Protection: Over-voltage, over-current, over-temperature
• Form Factor: 3U rack mount (5.25 inches / 13.34 cm height)
– 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.
