This B&K Precision triple-output programmable linear DC power supply unit provides a constant source of DC voltage for powering and testing electronic devices. The power supply unit (PSU) has two outputs that each provide adjustable DC voltage and current. A third output supplies fixed DC voltage up to 5V and current up to 3 amp, for applications such as supplying power to logic circuits. The PSU has separate knobs on the front panel for independently adjusting the output voltage and current of the variable outputs. The unit's four LED screens show voltage and current readings for the variable outputs simultaneously and are readable in low light. The variable outputs can be connected in series to supply more voltage, or they can be connected in parallel to supply more current. Multiple PSUs can be connected in series and parallel, as well. A power cord with a three-prong plug is included for connecting the PSU to a grounded outlet, and two pairs of test leads are included for testing applications. A built-in cooling fan helps prevent overheating, and a fuse turns off the unit in case of overload, helping to prevent damage to the PSU and the device under test. This B&K Precision power supply unit is offered with a choice of rating voltage and current for the variable outputs, accuracy, line and load regulation, ripple and noise characteristics, and weight.

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.
