This Instek GPR-H series single-output linear DC power supply unit provides a constant source of DC voltage and current for powering and testing electronic devices. The power supply unit (PSU) has one output that provides adjustable DC voltage up to the rating voltage and current up to the rating current. Potentiometer knobs on the unit's front panel allow for fine and coarse adjustment of the voltage and current output. A digital LED screen shows voltage and current readings and is readable in low light. The PSU features continuous or dynamic internal load selection for applications such as pulsed current. Two units can be connected in series to provide more voltage. A power cord with a three-prong plug is included for connecting the PSU to a grounded outlet, and a test lead is included for testing applications. A built-in cooling fan helps prevent overheating, and overload protection and reverse polarity protection help prevent damage to the PSU and the device under test. This Instek GPR-H series power supply is offered with a choice of

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.
