AutomationDirect has added new phase and voltage monitoring relays from ProSense. The PMRU-2C series true RMS phase monitor relays protect 3-phase equipment from damage that can occur when there is a ...

Knowing the correct phase connectivity information plays a significant role in maintaining high-quality power and reliable electricity supply to end-consumers. However, managing the consumer-phase ...

In the original version of this article, the second figure contained an error. The image has been updated. It’s important for engineers to have a good, working ...

It’s impossible to balance line-to-line voltages perfectly in three-phase circuits, so they typically differ by a few volts or more. However, if voltage unbalance exceeds 1%, it can markedly decrease ...

Flex Power Modules has introduced its first two-phase voltage regulator module (VRM), the BMR510, with a continuous total output current of 80 A (40 A per phase continuous current). It can deliver a ...

The phase-shifted full bridge (PSFB) shown in Figure 1 is popular in applications >500 W because it can achieve soft switching on its input switches for high converter efficiency. Although switching ...

As utility-scale solar projects accelerate the transition to 2kV system architectures, the industry is increasingly focused ...

My company is putting together a server room. We've got a massive Eaton/Powerware 9xxx-series UPS for the entire room. It's capable of running higher voltage (looks like 240V instead of 120). What's ...

Applying computer models and phase detection, SCE seeks to protect fire-prone areas by cutting power to falling lines before they touch the ground, Southern California Edison work crews install radio ...

The 100 V Gen 2 TMBS rectifier modules from Vishay Intertechnology are fully insulated devices in a compact SOT-227 package ...
