Instek GPS-3030DD Dual Display, Single Output Power Supply

The Instek GPS-3030DD is a single-output linear DC power supply delivering 90 W across 0–30 VDC at 0–3 ADC. Dual 3½-digit LED displays (0.39" each) provide simultaneous voltage and current readout with ±(0.5% of reading + 2 digits) accuracy. The supply operates in constant voltage (CV) and constant current (CC) modes, each with independently adjustable output via coarse and fine potentiometers.
