These days, homeowners are clamoring for pendants that hang from the ceiling, moody undercabinet lighting, recessed lighting and outdoor path lights that illuminate the edge of the front walk. Of ...

Rosslyn, Va.-based National Electrical Manufacturers Association (NEMA) recently announced the initiation of the NEMA Premium Efficiency Transformer program, which will help utilities, commercial ...

Each of the three basic types of light sources — incandescent, fluorescent, and HID — has its own particular applications and advantages. The proper selection of a lamp type will ultimately depend on ...

The circuit diagram was designed to create a power supply without utilizing any transformer circuit. This circuit illustrates the advantages as well as the safety precautions to keep in mind. Power ...

Among regulators, the simplest regulator circuit is for a low-dropout (LDO) voltage regulator whose topology is shown in Fig. 1. As a linear voltage regulator, its ...

When you design a transformer for any power converter, you face several compromises. You must trade off core size against the number of primary turns and flux density. Another trade-off is the number ...

step-down transformers decrease the voltage. The transformer in the diagram above is a step-down transformer – there are fewer turns on the secondary coil than on the primary coil. Type of transformer ...

The low-voltage motors from Wolong Electric America are engineered for horizontal pumping and compression duties, delivering up to 1,500 horsepower at 460 V, a power level traditionally achieved using ...
