The GW Instek GPD-3303S is a 3-channel programmable linear DC power supply with USB/serial connectivity.

See GW Instek GPD series for information common to all devices in this series.


There was two hardware revisions (versions) of these units released. Model numbers did not change so it is difficult to determine whether unit is the "old" or "new" hardware revision.

For GPD-3303S there was slight change to unit front panels; older units have slight space in output jacks between "CH1" and "FIXED" channel, while newer units have even spacing.

Known firmware versions:

Firmware Hardware Revision Notes
v1.06 Old Apparently last firmware for "old" HW revision.
v2.09 New
v2.11 New

It would appear that older hardware revision units have firmware version < v2.00, but this has not been confirmed.



See the vendor user manual for details.
