GPD-3303S: The digitally controlled GPD-3303S DC power supply offers digital panel control, bright LED indicators, large display, high output resolution, 4 sets of setup memory, USB remote control and smart cooling fan control. The GPD-3303S also provides easy operation, a quick selection of panel settings and most importantly, a reasonable price. Combining all of this makes the GPD-3303S the most promising new comer in the power supply market. With 1mV/1mA high resolution, the GPD-3303S, guarantees clean and stable output. You can easily simulate the device under test''''s accurate behavior against small changes in voltage or current, which is impossible when using a low-resolution power supply. Overall, the resolution offered by the GPD-3303S is 10 to 100 times higher than that of traditional power supply. The GPD-3303S can save and recall panel settings, a feature which is usually not offered by general power supplies. You can quickly select a panel setting from 4 memory sets without manual configuration. The USB device port in the GPD-3303S allows you to remotely control the power supply according to your application needs.
