Power supplies are devices that produce AC or DC power.  This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters

Impact hammers are used in structural and modal analysis to determine component or system response to impacts of varying amplitude and duration. A hammer with a force transducer in its head is paired with an accelerometer on the component being tested to compare impact and response

DC power supplies accept an input power and output the desired form of DC power. Common types of DC power supplies include linear power supplies, switching power supplies, DC-DC converters, and silicon controlled rectifier (SCR) type power supplies

High voltage power supplies use linear technology to provide one or more DC outputs at voltage levels of hundreds or thousands of volts

Power tools encompasses a wide range of devices, frequently motor-driven, for fabrication, assembly, construction, and repair across all industries and applications

Crushers and mills are used to reduce chemicals, materials or other products to a desired particle or aggregate size range.

Power distribution units (PDUs) have an electrical input and several outputs, often as electrical outlets, for powering multiple devices. 

AC power cords carry alternating current from one area to another. There are many different standard plugs and voltages, depending upon the country

PV and solar power systems convert light into electricity. They are the building blocks of photovoltaic (PV) modules

Power transformers convert power-level voltages from one level or phase configuration to another.  They can include features for electrical isolation, power distribution, and control and instrumentation applications

Power take-offs (PTOs) are extensions of a vehicle's drive train that can be engaged to power auxiliary equipment such as plows, augers, winches, and many other material handling, construction, and agricultural implements

Computer power supplies convert alternating current (AC) line to direct current (DC) line, needed by the computer

Single phase uninterruptible power supplies (UPS) sit between an AC outlet (i.e., a wall outlet or power strip) and an electronic device (e.g., computer, server, or phone equipment) to provide power conditioning, back-up protection and distribution for electronic equipment loads

SCR power supplies use silicon controlled rectifier (SCR) topology to provide well-regulated voltage and current output

DC power systems provide continuous DC power through multiple outputs.  Most DC power systems include a battery backup, temperature compensation, and other features
