Linear power supply unit provides a constant source of DC voltage and current for powering and testing electronic devices Two outputs supply adjustable voltage up to 30VDC and current up to 3 amp Third output supplies fixed voltage of 2.5V, 3.3V, or 5VDC and current of 3 amp Digitally controlled knobs for fine and coarse adjustment of voltage and current output Four LED screens show voltage and current readings for all outputs simultaneously The Instek GPD-3303D triple-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 adjustable outputs that each provide DC voltage up to 30V and current up to 3 amp. A third fixed output provides 2.5V, 3.3V, or 5VDC voltage and 3 amp current. Digitally controlled knobs on the unit's front panel allow for fine and coarse adjustment of the voltage and current output of the two 0 to 30V outputs. Four LED screens show voltage and current readings for all outputs simultaneously. The outputs can operate independently, and the two 0 to 30V outputs 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.
