GPD-3303S/GPD-3303D 195W Triple Output Programmable Linear D.C. Power Supply New Product Announcement Instek America Corp. is announcing to the global market the new triple output programmable DC power supply series, GPD-3303S / GPD-3303D. It 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.
Main Features
High Resolution
With 1mV/1mA high resolution (GPD-3303S only) also coarse and fine volume control, the GPD-3303S / GPD-3303D guarantees clean and stable output. You can easily simulate the device under test's accurate behavior against little changes in voltage or current, which is impossible when user were using lower resolution power supply. Overall, the resolution offered by the GPD-3303S is 10 to 100 times higher than the traditional one. Display ： 1mV / 1mA High Resolution For GPD-3303S Only. GPD-3303S NPI Announcement.doc

Manual or Remote Output on / off Control
To avoid the damage over DUT caused by improper user setting, GPD-3303S / GPD-3303D is equipped with a protective device of output on / off switch. Users can preset the voltage and current as needed, check the DUT connection then turn on the output manually to ensure a safe operation. The GPD-3303S / GPD-3303D also provides a USB device port which allows you to remotely control the power supply based on customer application needs. USB DEVICE PORT
Series or Parallel Function
Other than independent output mode that the GPD-3303S / GPD-3303D can operate under either Series mode or Parallel mode, which enables a broader output coverage of either 60V / 3A (Series Mode) or 60V / 3A (Parallel Mode).
Intelligent Cooling Fan Control
Smart cooling fan control offers a well balanced cooling mechanism, ensuring a quite operation under low power output condition.

Digital Control Panel
GPD-3303S / GPD-3303D come with a digital control panel instead of a traditional control one. With this new feature GPD-3303S / GPD-3303D is capable of providing more innovative functions, such as SAVE / RECALL memory sets, which allow user to restore the oft-repeated settings to save time, and the key-lock function, which prevents the accidental change of voltage / current setting to protect DUT. Besides, all the soft keypads with indication backlights provide user with a clear view of the setting and operation status of the product. The friendly human interface of GPD-3303 series greatly facilitates the ease of operation and increases the efficiency of work.
