- Linear power supply unit provides a constant source of DC voltage and current for powering and testing electronic devices requiring high current
- Unit can be set to supply constant current when no load is present
- Remote sensing feature compensates for degradation in regulation due to voltage drop in the load lead
- LED screen shows voltage and current reading simultaneously and is readable in low light
- RS-232 interface for connecting 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 that require high current. The power supply unit (PSU) has one output that provides adjustable DC voltage. The unit can be set to supply constant current when no load is present, and the remote sensing feature compensates for degradation in regulation due to voltage drop in the load lead. The LED screen shows the voltage and current reading simultaneously, and the display is readable in low light. The PSU stores the most recent operational settings and recalls them at startup. The PSU has an RS-232 interface for connecting to a computer (cable sold separately) so that it can be controlled remotely. Software download is included for remote control and testing applications. The output voltage can be remotely programmed with an external voltage resistor via an external resistance programming selector on the rear panel of the unit. A power cord with a three-prong plug is included for connecting the PSU to a grounded outlet. Overload and reverse polarity protection help 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, ripple and noise characteristics, and maximum power .

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.
