KUAIQU SPPS-D303XR 30V 3A 90W Precision Linear DC Regulated Power Supply 

Product Overview

The KUAIQU SPPS-D303XR 30V 3A 90W Precision Linear DC Regulated Power Supply is designed for PCB testing, electronics R&D, sensor testing, and low-power circuit development. With a 0–30V adjustable output, up to 3A current, and 90W output power, it provides stable and precise DC power for electronic circuits and modules.

Built around a full-power copper toroidal transformer, the SPPS-D303XR delivers an ultra-low ripple linear power supply output that is well suited to sensitive electronic testing. The 10mV voltage and 1mA current adjustment resolution allows fine output adjustment, while the 2.8-inch full-color LCD displays voltage, current, and voltage/current waveform curves during testing.

The SPPS-D303XR also combines programmable ramp-up, cycle testing, 99 groups of data storage, and RS232/RS485/USB communication, making it more than a conventional bench supply for repeatable laboratory testing.
