The KUAIQU SPS305C 30V 5A DC power supply is a compact 150W bench DC power supply designed for electronics technicians, PCB repair professionals, engineers, hobbyists, and DIY users. With 0–30V adjustable output and up to 5A current, this 30V 5A power supply provides stable and precise power for PCB repair, circuit debugging, electronic component testing, and prototype development.
The SPS305C is particularly useful in electronics repair workshops, engineering benches, educational laboratories, and DIY electronics workstations, where technicians need a reliable 30V adjustable power supply for electronics testing. It can be used to power circuit boards during troubleshooting, verify component behavior, and monitor abnormal current consumption.
Adjustable DC Output for PCB Testing:
The SPS305C provides 0–30V and 0–5A adjustable output, delivering controlled power for circuit boards, sensors, modules, and electronic components. As a 30V 5A DC power supply for PCB repair, it allows technicians to gradually apply voltage while observing current consumption.
Smart Battery Charging:
Reverse polarity protection helps prevent accidental damage caused by incorrect battery connections. Overcharge protection automatically stops charging when the battery reaches full capacity, while real-time Ah monitoring provides useful information for battery charging and electronics testing.
Multi-Protocol USB Fast Charging:
USB-A supports PE1.1/2.0, Apple BC1.2, AFC, FCP, and QC2.0/QC3.0, while USB-C supports PE1.1/2.0, Apple BC1.2, AFC, FCP, QC2.0/QC3.0, PD3.0, and PPS, making it convenient for charging and testing modern portable electronics.
Protection for Electronics Repair:
Integrated OCP (Over Current Protection) helps protect connected circuits when excessive current occurs during PCB troubleshooting, circuit debugging, and electronic component testing.
Precision Bench Control:
The encoder knob enables accurate voltage and current adjustment, while optional audio feedback makes repeated parameter changes easier during electronics repair and laboratory testing.
PCB Repair & Circuit Troubleshooting
Use the SPS305C as a PCB repair power supply to safely power circuit boards during fault diagnosis, short-circuit detection, and component replacement.
Electronic Component Testing
Engineers can use this electronics testing power supply to evaluate sensors, IC modules, small motors, LEDs, and other low-voltage components under controlled DC conditions.
DIY & Prototype Development
For makers and hobbyists, the SPS305C works as a 30V power supply for electronics hobbyists, providing adjustable power for Arduino projects, DIY circuits, development boards, and prototypes.
Educational Electronics Labs
Its adjustable output and real-time monitoring make it suitable for students learning circuit behavior, voltage regulation, current consumption, and basic electronics testing.
