The KUAIQU SPPS-K305 Precision DC Power Supply is designed for engineers working on wearable devices, IoT nodes, battery-powered electronics, and low-power embedded systems.
With 10μA current readback resolution under 20mA, automatic A/mA range switching, and stable low-noise output, the SPPS-K305 helps engineers accurately measure sleep current, standby power consumption, and micro-power changes during product development and debugging.
Whether you are testing an IoT sensor, optimizing battery life, or debugging low-power circuits, SPPS-K305 provides the precision needed for modern electronic development.
Modern battery-powered devices often consume only microamps or milliamps during standby operation. Traditional power supplies may not provide enough resolution to identify small current variations.
SPPS-K305 features:
✅ Automatic A/mA current range switching
✅ Current setting resolution: 1mA
✅ Current readback resolution: 10μA (<20mA range)
This allows engineers to accurately analyze:
Low-power electronics require stable and accurate power sources throughout the development cycle.
SPPS-K305 is ideal for:
Battery life is one of the most important factors for portable electronics.
During development, engineers need to identify:
The SPPS-K305 provides stable output and high-resolution current measurement to help engineers:
✔ Compare different power-saving modes
✔ Optimize firmware power management
✔ Verify low-power design performance
✔ Extend battery operating time
With a maximum output of:
0-30V / 0-5A / 150W
SPPS-K305 supports a wide range of electronics testing applications.

| Parameter | Value |
|---|---|
| Output Voltage | 0-30V |
| Output Current | 0-5A |
| Output Power | 150W |
| Voltage Setting Resolution | 1mV |
| Current Setting Resolution | 1mA |
| Voltage Accuracy | 0.05% + 10mV |
| Current Accuracy | 0.1% + 10mA |
The high-resolution display provides clear monitoring of:
Engineers can quickly identify abnormal conditions and avoid repeated debugging caused by inaccurate measurements.
The SPPS-K305 includes:
✅ 4 groups of stored output settings
Save commonly used parameters and quickly switch between test conditions.
Useful for:
Protect your valuable prototypes with:
Automatically protects the power supply and connected devices during accidental shorts.
Prevents excessive voltage from damaging sensitive circuits.
Limits current output to protect low-power electronics.
Prevent accidental parameter changes during long-term testing.
