KUAIQU SPPS-Q305 30V 5A 150W Precision DC Power Supply for PCB Repair &Electronics Testing

KUAIQU SPPS-Q305 30V 5A 150W Precision Bench DC Power Supply Product Overview The KUAIQU SPPS-Q305 30V 5A DC Power Supply is a precision bench power supply designed for PCB repair, electronics testing, circuit debugging, and small electronic devices. With an adjustable 0–30V output, up to 5A current, and 150W maximum power, it provides stable and controllable DC power for development boards, sensors, electronic modules, routers, and other low-to-medium power equipment. The SPPS-Q305 combines a color LCD display, USB-A and USB-C fast charging, real-time USB monitoring, and OCP, OVP, and OPP protection in a compact bench power supply. When working with low-voltage circuits, the display provides three decimal places below 10V, allowing users to observe small voltage changes more precisely. Key Features 0–30V Adjustable DC Output: Provides up to 5A and 150W for PCB repair, circuit debugging, development board testing, sensor testing, and small electronic devices. Color LCD Display: Clearly displays output voltage, current, and power, making it convenient to monitor circuit conditions during electronics testing and repair. High-Resolution Low-Voltage Display: When the output voltage is below 10V, voltage is displayed to three decimal places for more detailed low-voltage circuit testing. OCP, OVP & OPP Protection: Built-in over-current, over-voltage, and over-power protection helps protect the power supply and connected electronics against abnormal operating conditions. USB-A & USB-C Fast Charging: Dual USB-A and USB-C ports provide up to 18W USB output and automatically adapt to supported charging protocols. Real-Time USB Monitoring: USB voltage and current are displayed in real time, making it convenient to monitor USB charging and test USB-powered devices. Automatic A/mA & W/mW Conversion: Current automatically switches between A and mA, while power switches between W and mW according to the measured value for easier reading. Output ON/OFF & Panel LOCK: The dedicated output button allows quick power control, while the LOCK function helps prevent accidental panel operation during testing. Buzzer Alarm with Mute: Audible alerts provide operating and protection notifications, while the buzzer can be muted when silent operation is preferred. Applications PCB Repair & Troubleshooting: Provides adjustable DC power for PCB repair, circuit troubleshooting, and electronic maintenance. Development Board Testing: Suitable for Arduino, Raspberry Pi, MCU boards, and other low-voltage development platforms. Sensor & Module Testing: Suitable for sensors, relay modules, control modules, and other electronic components requiring adjustable DC power. Small Electronic Devices: Suitable for routers, small networking devices, consumer electronics, and other low-to-medium power DC equipment. Electronic Component Testing: Useful for testing electronic components and circuit modules under controlled voltage and current conditions. DIY Electronics Projects: Suitable for circuit prototyping, hobby electronics, and small DC projects. The SPPS-Q305 is a practical 30V 5A bench power supply for electronics testing, particularly when detailed low-voltage adjustment, convenient USB connectivity, and clear real-time monitoring are important.
