Tektronix PS280 30V/2A Triple Output Power Supply

The Tektronix PS280 is a benchtop triple-output DC power supply built for electronic testing and development work. It delivers one fixed 5V @ 3A output plus two independently adjustable outputs rated 0 to 30V @ 0 to 2A each. Three operating modes—independent, series tracking (0 to 60V @ 0 to 2A), and parallel tracking (0 to 30V @ 0 to 4A)—adapt to diverse circuit requirements. Automatic CV/CC crossover transitions between constant voltage and constant current as load conditions change, while adjustable current limiting on each variable output provides protection and precise load control.

– Technical Specifications

• Output Configuration: Three outputs—one fixed at 5V @ 3A, two variable at 0 to 30V @ 0 to 2A each
• Series Tracking Mode: 0 to 60V @ 0 to 2A (master-controlled voltage)
• Parallel Tracking Mode: 0 to 30V @ 0 to 4A (master-controlled voltage and current)
• Voltage Ripple and Noise: 2000 µV
• Current Ripple and Noise: 3 mA
• Load Regulation (Voltage): 10 mV
• Load Regulation (Current): 3 mA
• Line Regulation (Voltage): 5 mV

– Key Features

• Constant voltage/constant current (CV/CC) crossover protects loads and allows flexible operation across resistive, capacitive, and inductive circuits
• Adjustable current limiting on variable outputs enables precise supply behavior customization
• Digital LED output indicators display real-time voltage and current values
• Independent control mode isolates each variable output for multi-rail test configurations
• Compact, lightweight benchtop design supports both fixed lab setups and portable measurement scenarios

– Typical Applications

Ideal for powering and testing analog circuits, digital logic modules, embedded systems development, and educational laboratory work where multiple independent or coordinated supply rails are required.

– Compatibility & Integration

Operates from standard AC mains (≤250 V rms between supply conductors or between either conductor and ground). Protective ground connection via power cord is mandatory for safe operation. Output terminals provide standard red (positive), black (negative), and green (earth/chassis ground) polarity designation.
