The KUAIQU SPPS-H305 is a 0–30V, 0–5A continuously adjustable DC bench power supply, designed for precision electronics work, repair, and laboratory testing.Built for engineers and technicians who require accurate voltage and current control, it features a dual coarse & fine adjustment knob system, allowing ultra-precise tuning for both voltage and current settings.
This regulated DC power supply provides a wide and stable output range, making it suitable for electronics repair, laboratory testing, R&D development, and industrial electronic applications requiring precise voltage and current control.
As a professional adjustable bench power supply, it features independent coarse and fine tuning for both voltage and current, allowing fast setup as well as highly accurate micro-adjustments for sensitive electronic circuits and lab testing environments.
This digital lab power supply is equipped with a high-resolution 4-digit display that shows voltage and current in real time, ensuring precise monitoring during electronics repair, PCB debugging, and engineering development work.
Designed as a low noise regulated DC power supply, it delivers clean and stable output with minimal ripple, making it safe for ICs, microcontrollers, sensors, and other sensitive electronic components used in R&D and prototype testing.
This bench DC power supply includes over-current, over-voltage, and over-temperature protection, ensuring reliable and safe operation in laboratory testing, electronics repair stations, and industrial maintenance environments.
The regulated power supply automatically shuts down and triggers an alarm under abnormal conditions such as overload or short circuit, effectively protecting both the power supply unit and connected devices.
This laboratory power supply includes a USB 5V output port, providing convenient power for development boards, embedded systems, and small electronic devices commonly used in engineering and prototyping work.
Designed as a compact bench power supply, it fits perfectly on workbenches in repair shops, laboratories, and engineering desks, making it ideal for continuous daily use in professional environments.
Perfectly suited for low to medium power applications, especially where precise voltage and current limiting are critical.
Widely used in:
Electronics repair workshops
PCB debugging and prototyping
Laboratory testing and education
R&D engineering development
Small-scale production testing
Its compact bench-top design makes it ideal for desktop use in professional and educational environments.
