As the demand for electrical power increases, distribution systems are expanded to accommodate the increased demand. Stiffened transmission systems, increased substation capacity, and added on-site and distributed generation all contribute to increases in available fault currents.

Variable frequency drives (VFDs) save energy, increase the life of mechanical systems, and offer valuable control features in a wide range of building management applications.

Danfoss has launched new models for its Turbocor® TG series for low global warming potential refrigerants. The compressors enable chiller manufacturers to build climate friendly and sustainable solutions that support refrigerant regulations for reducing the direct and indirect CO2 emissions such as the European F-Gas Regulation and the US Environmental Protection Agency’s SNAP regulations.

B&K Precision is offering three new models of its high power programmable DC power supplies, models PVS10005, PVS60085, and PVS60085MR. The new PVS Series delivers output power up to 5.1 kW. The company says they deliver excellent regulation, low noise, and fast transient response times. All models provide a built-in solar array simulator (SAS) function to generate photovoltaic I-V curves. Offering high-power density in a compact 2U form factor, these DC power supplies are suitable for high voltage testing up to 1000 V, motor inverter testing, and solar array testing applications.

The AMS5105 pressure sensor is available with two switching outputs.
