Overvoltage protection of AC power lines is a common practice, which encompasses a variety of protection circuit solutions. Most designs are cost-driven and tend to use only the bare minimum of ...

Since the earliest versions of indoor LED light bulbs were developed, their designers have faced a variety of technical challenges. These include AC-to-DC power conversion, thermal design/heat-sinking ...

Article 440 applies to electrically driven air-conditioning (A/C) and refrigeration equipment. Each equipment manufacturer has the compressor motor built to its own specifications. The motors are ...

Common methods used to measure current. A new approach to current sensing: GaNSense technology. For any electrical control system, input signals of both voltage and current are critical for the system ...

Motors used for refrigeration equipment (including air conditioning systems) are hermetic. When we say “hermetic,” what do we mean? It’s a motor that’s sealed from the outside. In the case of ...

Power protection is like insurance: You pay for it, yet hope you don’t need it. But it’s not a simple “purchase.” The first protection question is, “What am I seeking to protect and against what event ...
