Overview
The P3000 Series 3CH DC Power Supply provides two independently adjustable output channels and one fixed 5V / 3A output channel. It supports precise voltage and current adjustment with up to 10mV / 1mA resolution, making it suitable for circuit testing, electronic development, maintenance, and production environments. The series includes configurable OVP/OCP protection, soft-start circuitry for low inrush current, adjustable voltage/current range limits, buzzer control, and one-touch restoration to default settings. With series and parallel configuration support, users can combine outputs and directly view the combined voltage and current, improving flexibility for different testing requirements.
