The Keysight N7970A Advanced Power System is a dynamic DC power supply engineered for automated test equipment (ATE) applications requiring high-speed dynamic sourcing and measurement capabilities. Operating at 9 V, 200 A, and 2000 W, this single-output 2U rack-mount unit leverages Keysight’s VersaPower architecture to deliver test speeds up to 100x faster than standard system power supplies while maintaining 18-bit measurement precision.
Technical Specifications
• Output Rating: 9 V, 200 A, 2000 W
• Measurement Precision: 18-bit (voltage and current) with DMM-like accuracy
• Programming Precision: 16-bit (voltage and current)
• Command Processing Speed: < 2 ms
• Programming Speed: Up to 500 µs (up/down transitions)
• Measurement Rate: Adjustable for speed/accuracy trade-off
• Form Factor: 2U rack mount, single output
– Key Features
• Two-Quadrant Operation: Smooth transitions between positive and negative currents with programmable current limits and waveforms. Standalone units support 10% rated current; full two-quadrant operation requires the N7909A power dissipater.
• Output Disconnect Relay: Included for output isolation control.
• Paralleling Capability: Up to 10 kW total output achievable by paralleling units with equal current sharing via three-wire rear panel connection.
• VersaPower Architecture: Delivers speed paired with high-precision measurement.
• Software Integration: APS Power Assistant (free), BenchVue for PC-based control and automated test development, and optional Black Box Recorder (N7908A accessory) for event logging and data analysis.
– Typical Applications
• High-speed dynamic sourcing and load testing
• Power storage and battery simulation
• Automated production test environments requiring rapid command response
– Compatibility & Integration
The N7970A integrates with Keysight software suites for test automation and measurement analysis. Paralleling capability enables scaled power delivery for systems exceeding single-unit output ratings.
