Product description

Size:2 Channels, 1mV/1mA Minimum Resolution

The Instek GPD-2303S dual-output programmable 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 two outputs that each provide DC voltage up to 30V and current up to 3 amp. Digitally controlled knobs on the unit's front panel allow for fine and coarse adjustment of the voltage and current output. The PSU has a resolution of 1mV (millivolt) or 1mA (milliamp), which allows the user to observe the device under test's response to small changes in voltage and current. Four LED screens show voltage and current readings for all outputs simultaneously. The outputs can operate independently, or they can be connected in series to supply more voltage or in parallel to supply more current. A lock function disables the unit's front-panel keys to help prevent accidental input. The PSU's internal memory can store up to four sets of front-panel settings for future recall. The PSU has a USB port for connecting to a computer for remote control (USB cable sold separately). Software is included for testing applications and for emulating the PSU's front-panel controls. The unit's LED screens are readable in low light. A power cord with a three-prong plug is included for connecting the PSU to a grounded outlet, and test leads are 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. For regulation and ripple and noise characteristics, see the unit's datasheet.

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.
