• About this item.
• Linear power supply unit provides a constant source of DC voltage and current for powering and testing electronic devices One output provides adjustable voltage or current Internal memory stores up to 16 operating states for future recall Vacuum fluorescent display is readable in low light Includes RS-232 communication cable to connect the PSU to a computer for remote control.

This B&K Precision single-output, programmable linear DC power supply unit provides a constant source of DC voltage and current for powering and testing electronic devices in research and development, production, and laboratory applications. The power supply unit (PSU) has one output that provides DC voltage and current. The voltage and current output can be adjusted, and the PSU's internal memory can store up to 16 operating states for future recall. The unit's vacuum fluorescent display (VFD) is readable in low light. The PSU has an RS-232 interface for connecting to a computer (cable included) so that it can be controlled remotely. Software is included for remote control and testing applications. An output on/off switch enables or disables the output, helping to prevent damage to the device under test. A lock feature disables the front-panel keypad to help prevent accidental input. The PSU can sit on a workbench or be ed in a rack (ing hardware sold separately), and it has a removable handle for carrying or for propping up the meter during use. A power cord with a three-prong plug is included for connecting the PSU to a grounded outlet. The PSU's cooling fan helps prevent overheating, and built-in overload protection helps 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, and weight ( https://images-na.ssl-images-.com/images/G/01/BISS/SpecSheets/BKPrecision/B00B03XF7Q.pdf ).

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 a 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 sw-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.
