GPD-3303S/3303D
The GPD-3303S / GPD-3303D series inherits the superior technology and high quality, which GW Instek
has established through its long history of power supply design and manufacturing. The GPD-3303S /
GPD-3303D series provides 195W output power, three isolated output channels, high resolution output
(GPD-3303S ), digital control panel, 4 sets of setup memory, USB remote control, smart cooling fan
control, high reliability, and compact size. The GPD-3303S / GPD-3303D establish a new benchmark for
economic programmable linear D.C. power supply market segment. The most remarkable feature of
this series product with minimum 1mV / 1mA resolution of GPD-3303S, which right fits into the
applications needing accurate control of power source.GPD-3303D, another member of the family, is
considered a digitally-upgraded version of GPS-3303. Besides the same power output features and the
common specifications of GPS-3303, that GPD-3303S / GPD-3303D has a bigger display for Voltage
and Current readings, a digital panel, and a USB port, which lifts up the product to a programmable
device at a little additional cost.
