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.

Key Features

0–30V / 0–3A Adjustable Linear Output: Provides up to 90W for PCB testing, sensors, development boards, electronic components, and other low-power circuits.
Precision 10mV / 1mA Adjustment: Fine voltage and current adjustment provides detailed control for electronics testing and circuit development.
Full-Power Copper Toroidal Transformer: The transformer-based design provides stable output and supports the low-ripple linear DC power supply characteristics required for sensitive electronic circuits.
Ultra-Low Ripple Output: Designed to provide clean and stable DC power for applications where low output ripple is important.
2.8-Inch Full-Color LCD: Clearly displays output voltage and current while providing a visual interface for monitoring test parameters.
Voltage & Current Waveform Display: Real-time voltage and current curves help users observe output changes during circuit testing.
Programmable Ramp & Cycle Testing: Supports controlled voltage/current ramp-up and programmable repeated cycles for repeatable test procedures.
99 Groups of Data Storage: Stores and recalls up to 99 sets of voltage and current parameters for frequently repeated tests.
OCP & OVP Protection: Over-current and over-voltage protection helps protect the power supply and connected equipment.
USB 5V/2A Output: Provides auxiliary USB power with real-time USB voltage and current display.
RS232 / RS485 / USB Communication: Enables computer communication and integration with automated test systems.
Screen Lock & Buzzer: Prevents accidental parameter changes and provides audible operating or protection alerts.

Applications

PCB Testing & Repair: Suitable for powering, troubleshooting, and repairing low-power circuit boards.
Electronics R&D: Suitable for prototype development, circuit debugging, and laboratory electronics research.
