The Keysight N8923A is a 5 kW autoranging programmable DC power supply engineered for ATE and production test environments. This single-output 3U rackmount unit delivers 0–500 V and 0–30 A with full 5000 W power density across the entire voltage-current matrix. Autoranging capability enables flexible voltage and current combinations—the supply automatically adjusts maximum current as voltage changes to maintain constant power delivery, effectively functioning as multiple power supplies in one.
The unit features built-in voltage and current measurement capability, essential for real-time load monitoring and system validation. Comprehensive protection circuitry includes over-voltage, over-current, and over-temperature safeguards, protecting both supply and load under fault conditions.
Technical Specifications
• Output Power: 5000 W
• Output Voltage: 0–500 V
• Output Current: 0–30 A
• Autoranging: Maximum current scales inversely with voltage to maintain constant 5 kW power rating across all operating points
• Input: 187–240 VAC, 50/60 Hz (nominal 208 VAC)
• Measurement: Built-in voltage and current readback
• Protection: Over-voltage, over-current, over-temperature
– Key Features
• Autoranging output—single unit replaces multiple fixed-range supplies
• Parallel operation: up to ten units can be connected for total output exceeding 100 kW using built-in parallel link
• Programmable control via LAN (LXI Core compliant), USB, GPIB, and analog interface
• High power density in compact 3U form factor
– Typical Applications
• Automated test equipment (ATE) systems
• Production test stands requiring flexible, high-current power delivery
• Multi-unit systems scaling beyond 100 kW
– Compatibility & Integration
Standard interfaces include LXI Core compliant Ethernet, USB, GPIB (IEEE 488), and analog control. The built-in parallel link allows seamless integration of multiple units without individual per-supply programming, simplifying system architecture.
