Test equipment is everywhere. Every trade show has it regardless of the focus. Power is no exception. At APEC 2024, EE World visited several booths displaying test equipment: meters, oscilloscopes, source-measure units (SMUs), bench power supplies, and electronic loads. The photos and videos below highlight what we saw, presented in alphabetical order by company. In […]

How to use remote sensing for DC programmable power supplies
In this FAQ, you’ll learn how to know if your test application needs sensing and how to properly wire a power supply to a load. Calibrating certain sensing circuits, such as those used in electric vehicles (EVs), is critical to get right. An inaccurate calibration of an automotive battery monitoring circuit could, for example, allow […]
Power units provides distribution and safety to automated test racks
nVent Electric plc announced the addition of common North American voltages to the Rack Safety Plus line of modular safety and power distribution units designed to protect and connect electronics enclosed within 19″ cabinets. Designed in collaboration with Test and Measurement customers, these 19” slide-in units provide power entry, power distribution, and safety features that […]
Automate double-pulse testing in WBG devices
By automating double-pulse testing of wide bandgap devices such as SiC and GaN power devices, you can cut setup and analysis time. The need to reduce carbon emissions drives investments in electrical technologies, particularly in data centers and electric vehicles. In its most recent Elective Vehicle Outlook report, Bloomberg estimates a 27% increase in global […]
Functional tester covers bench, production, and service applications
The midUTS from Bloomy contains a multimeter, data-acquisition, switching, and power supplies for testing boards and systems. Automating tests — whether for bench testing new designs, in production, or for service — increases productivity but comes at a price. If you’re going to build an automated test system all yourself, expect to specify the instrumentation, […]
Linear dc power supply excels with low current measurements
The DP2000 is a completely new benchtop power supply that features three fully isolated channels with automatic internal series and parallel connections and an intuitive 4.3-in touch screen. The DP2000 delivers high resolution for measuring low-range currents down to 1 µA, a high-speed sampling mode, an arbitrary output mode with a 1-msec dwell time, and […]
Selecting and applying programmable power supplies
A system-level view of testing is helpful when specifying power requirements. Jeff Brakley • Ametek Programmable Power Inc. There are numerous options available for programmable dc power supplies. Users can select from a wide range of voltage, current, and power ratings. Other specifications include input voltage, output voltage regulation, output ripple and noise, and transient […]
