Although variable dc power supplies might appear to be relatively simple instruments, engineers rely on them to deliver stable, precise, and clean voltages and currents, regardless of the load. To ...

Read an introduction to this series in Part 1, and Part 2, which covers noise. This is the third and final part in a series which discusses how to properly test a power supply to ensure it will work ...

Fnirsi is one of those brands that seem to pop up more and more often, usually for portable oscilloscopes and kin. Their IPS3608 bench power supply is a bit of a departure from that, offering a ...

This is a bench power supply with adjustable voltage and current limiting. [Sylvain’s] creation can regulate 0-25 volts while sourcing 0-5 amps. Current limiting is a nice feature as it will allow you ...

This three-part series describes how to properly test a DC/DC power supply, and ensure that it works reliably over various operating conditions. This series is intended to provide the designer with a ...

I'm looking for a power supply to do benchtop testing of automotive components. Ideally I'm looking for 110/120V input and 12-13.8V @ 15-20A output. This is going to be mounted inside a hutch on a ...
