High Resolution

With 1mV/1mA high resolution and coarse/fine volume control, the GPD-4303S guarantees clean and stable output. Using the GPD-4303S you can easily simulate the device under test, comparing accurate behavior against small changes in voltage or current, which is impossible when using a low resolution power supply.

Tracking Series and Parallel Function

Tracking series and parallel function allows you to use the GPD-4303S in a wide range of applications. The tracking series mode guarantees higher output voltage, while the tracking parallel mode guarantees higher output current.

Convenience Functions

The GPD4303S knobs are digitally controlled, allowing for fine or coarse volume settings. The key lock feature locks panel operations, preventing accidental settings changes, which might damage the equipment.

4 Sets of Save/Recall

The GPD-4303S can save and recall panel settings; quickly select a panel setting from the four memory sets without the need for manual configuration.

USB Remote Control

The USB device port in the GPD4303S allows you to remotely control the power supply according to your application needs.
