Hewlett-Packard 6632A Laboratory DC Power Supply

The Hewlett-Packard 6632A is an adjustable laboratory DC power supply that delivers a 0–20 V output with a maximum current of 5 A. The output range and current limit let you set precise load conditions for testing and debugging electronic circuits, making it suitable for bench-top work in research and development environments. This model is designed for general-purpose lab use, providing a stable, configurable source to power voltage regulators, op-amp circuits, microcontroller projects, motor drivers, and other DC-powered test setups. Its 0–20 V capability supports both low- and medium-voltage applications without needing multiple supplies, while the 5 A ceiling covers a wide range of small-load needs. Manufactured by Hewlett-Packard (HP), the 6632A represents a dependable option in a historic line of laboratory power supplies used for experimentation and evaluation. Users benefit from straightforward voltage adjustment and current limiting to protect sensitive devices during testing.
