GW Instek GPP-7250G Programmable DC Power Supply with GPIB

Overview

The GW Instek GPP-7250G is a 360W programmable DC power supply with a single output channel delivering 72V at 5A. It offers high programming resolution (2mV/0.1mA) and readback resolution (0.1mV/0.1mA) with exceptional low ripple noise characteristics (≤1mVrms, 5Hz–1MHz). This variant includes a built-in GPIB interface for remote programming and monitoring. The unit features a 4.3" TFT LCD display with multiple display modes.
