The KUAIQU SPPS-Q305 is a 30V 5A 150W PCB Repair Power Supply designed for PCB repair, embedded hardware development, circuit debugging, electronic component testing, and small electronic devices. As a high precision adjustable DC power supply, it provides accurate voltage and current control with real-time monitoring through a color LCD display. With OVP, OCP, OPP protection, USB-A and USB-C fast charging, and fine current monitoring, this 30V 5A DC power supply is well suited to technicians, engineers, makers, and electronics repair professionals.
30V 5A 150W High Precision DC Output
Provides adjustable 0–30V and 0–5A output with up to 150W power, making this 30V 5A power supply suitable for PCB repair, circuit debugging, embedded hardware, and electronic component testing.
PCB Repair Power Supply
Designed specifically for PCB repair and circuit debugging, providing controlled DC power for circuit boards, ICs, electronic components, development boards, and small electronic devices.
High Precision Voltage & Current Monitoring
The high-resolution color LCD displays voltage, current, and power in real time. Below 10V, the display provides 0.001V resolution, making it useful for low-voltage PCB testing and embedded system development.
Automatic A/mA and W/mW Display
The display automatically switches between A/mA and W/mW according to the measured output, making small-current measurements easier to read during electronic component testing and circuit troubleshooting.
OVP / OCP / OPP Triple Protection
Over-voltage protection, over-current protection, and over-power protection help protect connected PCBs, ICs, circuit boards, and electronic components during repair and development.
USB-A & USB-C Fast Charging
Built-in USB-A and USB-C outputs support up to 18W fast charging with automatic charging protocol recognition, providing additional power convenience for compatible devices and development equipment.
Precise Encoder Control
The encoder knob allows convenient voltage and current adjustment, providing efficient control during PCB repair, circuit debugging, and embedded hardware development.
Independent Output Switch
The output switch allows users to turn DC output on or off without repeatedly changing the preset voltage and current values.
PCB Repair: Controlled DC power for PCB troubleshooting, board repair, and circuit diagnosis.
Circuit Debugging: Adjustable power for circuit debugging and electronic system development.
Embedded Hardware: Suitable for embedded hardware, development boards, microcontroller projects, and control boards.
Electronic Component Testing: Useful for testing ICs, electronic components, and low-voltage circuits.
DIY Electronics: Suitable for makers and electronics enthusiasts working on prototypes and small electronic projects.
Repair Workshops: Practical bench power supply for electronics repair technicians.
Prototype Development: Adjustable DC power for early-stage electronic product development.
Small Electronic Devices: Stable power source for low-voltage electronic equipment.
