The KUAIQU SPPS-Q305 30V 5A adjustable DC power supply is designed for electronic equipment testing, electrical maintenance, and general-purpose DC power applications. With an adjustable output of 0–30V, up to 5A current, and 150W power capacity, it provides a versatile power source for evaluating electronic devices, checking electrical performance, and maintaining low-voltage equipment.
The color LCD display provides clear voltage, current, and power readings, making it easier to monitor output conditions during equipment testing and maintenance. Built-in overcurrent protection (OCP), overvoltage protection (OVP), and overpower protection (OPP) help protect connected equipment against abnormal output conditions.
Equipped with USB-A and USB-C fast-charging ports, the SPPS-Q305 supports compatible charging protocols with up to 18W USB output. Real-time USB voltage and current monitoring helps users observe charging performance, while automatic A/mA and W/mW conversion makes electrical readings easier to interpret. The output switch, panel lock, and mute function provide additional convenience for daily bench work.
Combining adjustable DC output, multiple protection functions, detailed measurement display, and integrated USB charging, the KUAIQU SPPS-Q305 is a practical bench power supply for electronic equipment evaluation, electrical troubleshooting, and routine maintenance tasks.
Adjustable 0–30V DC Output: Provides flexible voltage adjustment for electronic equipment testing and low-voltage electrical applications.
5A Output Current and 150W Power: Supports a wide range of compatible electronic devices and equipment maintenance tasks within its rated output capacity.
Color LCD Display: Shows voltage, current, and power for convenient monitoring during operation.
OCP, OVP, and OPP Protection: Helps protect connected devices against overcurrent, overvoltage, and overpower conditions.
