A load bank is a piece of electrical test equipment used to simulate an electrical load, to test an electric power source without connecting it to its normal operating load. [ 1 ] [ 2 ] During testing, adjustment, calibration, or verification procedures, a load bank is connected to the output of a power source, such as an electric generator ...
12 V and 24 V powered USB sockets, on an NCR cash register. PoweredUSB, also known as Retail USB, USB PlusPower, USB +Power, and USB Power Plus, [1] is an addition to the Universal Serial Bus standard that allows for higher-power devices to obtain power through their USB host instead of requiring an independent power supply or external AC adapter.
A programmable load is a type of test equipment or instrument which emulates DC or AC resistance loads normally required to perform functional tests of batteries, power supplies or solar cells.

Reactive power: The circulating current can differ from the current consumed when capacitive or inductive loads are used. Harmonic distortion: Non-linear loads may create distortion of the inverter waveform. Mismatch between load and inverter size: When a higher rated inverter is used for a lower capacity load, overall efficiency is reduced. [9]

The throughput of each USB port is determined by the slower speed of either the USB port or the USB device connected to the port. High-speed USB 2.0 hubs contain devices called transaction translators that convert between high-speed USB 2.0 buses and full and low speed buses. There may be one translator per hub or per port.
This kind of power electronics include gate turn-off thyristor, commonly used in high-voltage direct current (HVDC) transmission. Various accumulator systems may be used depending on the power-to-energy ratio, the expected lifetime and the costs. In the 1980s, lead-acid batteries were used for the first battery-storage power plants.
