The Elenco XP-100 single-output battery eliminator and DC power supply provides a constant source of DC voltage and current for powering and testing electronic devices. It can be used in place of most batteries, including AA, AAA, C, D, and 9-volt types. The power supply unit (PSU) has one output that supplies a fixed voltage of 1.5V, 2.2V, 3V, 4.5V, 5V, 6V, 7.2V, 9V, 10V, 12V, 13.8V, or 15VDC and current up to 1 amp. An integrated circuit (IC) holds output voltage within 0.2V when going from no load to a 1-amp load, and the output voltage will not increase while the output voltage settings are being adjusted. The PSU accepts an input voltage of 120V AC at 60 Hz, and a 2-amp fuse and thermal cutoff circuit help protect against short-circuits and overload.

H is the vertical distance from lowest to highest point, W is the horizontal distance from left to right, and D is the horizontal distance from front to back.

Power supply units (also known as PSUs, AC power supplies, DC power supplies, and battery eliminators) provide AC or DC voltage to power or test devices such as tools, appliances, and electronic components. The PSU draws energy from a line source such as a wall socket and converts it to a constant, specified amount of voltage or current that is then outputted to a connected device. In general, a power supply unit will be classified as either a linear PSU (also known as a linear regulation or line-frequency PSU) or a switched PSU (also known as a switching-mode power supply, SMPS, or switcher). Typically, a linear PSU has a simpler design and provides a faster transient response time and less electrical interference and noise than a switched PSU. A switched PSU is often smaller, lighter, and more efficient than a linear PSU and generates less heat. The transient response time of a PSU indicates how quickly the PSU can resume the desired constant output after a sudden change in input. Ripple voltage or current indicates how much unfiltered noise and AC voltage or current is present at the output of a filtered power supply operated at full load. The temperature coefficient is the percent average change in output voltage per degree centigrade of change in ambient temperature. Fuses, current limiters, and other forms of overload protection can be built into the PSU to help protect against voltage spikes or short-circuiting.
