The Instek GPC-6030D triple-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 two outputs that each provide adjustable DC voltage up to 60V and current up to 3 amp. A third output supplies fixed DC voltage of 5V and current of 3 amp. The outputs are independent from one another, and the unit has continuous or dynamic internal load selection. The PSU's 3-1/2 digit LED screen shows voltage and current output. The outputs can be connected in series to supply more voltage, or they can be connected in parallel to supply more current. When in tracking mode, one output can be set to supply a percentage of the voltage of the second output. The PSU can sit on a workbench or be mounted in a rack (mounting hardware sold separately). 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. The PSU meet European Conformity (CE) standards. For regulation and ripple and noise characteristics, see the unit's
