• Original GW Instek retail box

The images provided are of the actual item you will receive. Please review them carefully for the cosmetic condition and what is included in the sale.

The GW Instek GPS-3030DD is a single-output, 90W linear DC power supply from the GPS Series, designed for use in R&D, production, and laboratory environments. It features dual 3½-digit 0.39" LED displays showing voltage and current simultaneously, with separate coarse and fine adjustment potentiometers for both output parameters. The unit operates in constant voltage (CV) and constant current (CC) modes, with a Hi/Lo current range switch. Continuous or dynamic internal load selection supports applications including pulsed current. Rear-panel remote control terminals allow programming and operation from an external device. The GPS-3030DD supports series or parallel operation with tracking connection capability and accepts a wide-range AC input.
