Single Output DC Supplies
Single Output DC Supplies
Single output DC power supplies provide one isolated, regulated DC output and represent the most widely used power supply configuration in electronics engineering. They are available across a broad spectrum of output ratings — from low-voltage, high-current supplies for digital circuit development to high-voltage units for insulation testing and particle physics research. Autoranging models maximize output power utilization across the full voltage-current operating plane, while precision models offer sub-millivolt programming resolution and microampere-level current measurement for sensitive device characterization.
Many single output supplies feature remote sensing to compensate for voltage drops in test leads, programmable overvoltage and overcurrent protection, and standard communication interfaces (GPIB, USB, LAN/LXI) for integration into automated test systems. Battery simulator models add fast transient response and bidirectional operation to replicate the dynamic behavior of lithium-ion and other battery chemistries during charge and discharge cycles.
Typical Applications
- Powering and characterizing semiconductor devices, ICs, and RF components in R&D labs
- Battery simulation for mobile device, wearable, and IoT product development and testing
- High-voltage sourcing for dielectric testing of transformers, cables, and insulating materials
- Automated production test of power electronics and DC-DC converters
- Bias supply for amplifiers, mixers, and microwave components in communications and radar systems
- Precision current sourcing in electrochemistry, electroplating, and medical device R&D
