How advanced control strategies and system architectures contribute to sustainability
Doing something the same way as in the past rarely produces improved results. Technology is constantly evolving and improving, and new technologies can require new approaches. In the case of the power electronic systems discussed below, artificial intelligence (AI) and machine learning (ML) are common themes in these advanced control strategies and system architectures. Another […]

All models are voltage and current-programmable. In addition, these units are constant current […]
Generating really high voltages without a Tesla coil
There are many ways to create high-voltages and pulses; the Marx generator is a simple one in concept and practice. Low-voltage designs with rails in the single digits get a lot of attention these days for reasons I don’t need to detail to this audience. Still, there are many situations where rails at hundreds of […]
What to look for in surge protection for power supplies
By Ron Stull, CUI, Inc. Any mains-powered electrical device is vulnerable to voltage surge. These completely unpredictable events can take many forms: from modest power spikes during normal operation to massive power surges caused by an external lightning strike. To prevent damage and downtime, electrical equipment and circuits need to be provided with adequate surge […]
DIN-rail mount power supplies incorporate diagnostic and protection functions
Carlo Gavazzi announced compact, DIN-rail mount power supplies, the UL61010, and UL62368. Integrated diagnostic and protection functions such as output short circuit, over current, over-voltage, and over temperature provide the user with maximum output protection. Main technical features include: Universal input voltage range: 90 VAC to 264 VAC; 120 VDC to 370 VDC Output voltage […]
