Yes - many AC power sources can produce DC power, either alone or as a DC offset to an AC waveform. Can you use an AC power supply to produce DC power? Size is a crucial factor ATE power supplies with greater power density take up less rack space and reduce the factory floor space required for test equipment. What is an ATE system power supply?Īutomated test equipment (ATE) system power supplies are programmable power supplies designed for use in ATE systems. If you have a project that needs a specific voltage or haven’t designed the power section yet, a bench power supply can be a lifesaver. Variable bench power supplies are handy tools for testing circuits, as they allow you to adjust the voltage on the fly. In addition, the output terminals are easily accessible from the front. Users can also control modern bench power supplies via software. It will typically have a large, legible display and a user interface so engineers can easily control all aspects of the power supply from the front panel. What is a bench DC power supply?Ī bench DC power supply is designed to sit on an engineer’s bench. Linear power supplies can achieve lower noise, but modern switching supplies have minimized or eliminated this advantage. A switching power supply has higher efficiency, reduced weight, and smaller size. How does a DC power source work?Ī DC power source converts alternating current (AC) power into DC power using either a linear or switching methodology. Engineers can set voltages or current levels to power the device for testing purposes. How do you use a DC power source?Ī programmable DC power source connects to a DUT via leads that connect to the DC power supply panel. Why is a DC power source needed?Ī DC power source provides a constant biasing voltage or current to electrical devices, components, or circuits and ensures that the DUT operates as expected. Keysight variable DC power supplies allow you to change the voltage and the current to the DUT. It is a power source with an output voltage that the user can vary.
