KUAIQU SPPS-H305 30V 5A 150W Precision DC Power Supply
Product Description
The KUAIQU SPPS-H305 30V 5A 150W Precision DC Power Supply is designed for PCB repair, electronics troubleshooting, component testing, and circuit development. With an adjustable 0–30V voltage range and 0–5A current output, this precision DC bench power supply provides controlled power for low-voltage electronic circuits, development boards, sensors, modules, and individual components.
The 150W output capacity makes the SPPS-H305 suitable for everyday electronics service work where users need to adjust voltage and current according to different test requirements. The encoder-based control allows convenient parameter adjustment, while OCP and OVP protection provide additional safeguards during PCB testing and repair.
Key Features
- 0–30V / 0–5A Adjustable Output: Provides up to 150W of DC output power for PCB testing, electronic component evaluation, circuit debugging, and low-voltage electronics development.
- Encoder Knob with Adjustable Feedback: The rotary encoder provides convenient voltage and current adjustment during electronics repair, while the built-in beep can be muted when silent operation is preferred.
- Independent Output Switch: The dedicated output switch allows technicians to turn the DC output on or off without changing the preset parameters, which is convenient when replacing components or connecting a PCB.
- 5V 2A USB Auxiliary Output: The integrated USB port provides 5V/2A power for compatible USB-powered accessories used around an electronics repair workstation.
- OCP Current Protection: Over-current protection helps limit excessive current caused by short circuits, overloaded boards, or abnormal component conditions.
- OVP Voltage Protection: Over-voltage protection provides additional protection for sensitive electronic components and low-voltage circuits during testing.
- Bench-Oriented Operation: The straightforward control layout makes the unit suitable for repeated voltage and current adjustments during repair and laboratory electronics work.
Applications
The SPPS-H305 is particularly suitable for precision-oriented low-voltage electronics work, including:
- PCB repair and troubleshooting
- Mobile and consumer electronics board testing
- Electronic component testing
- Circuit debugging
- Development board testing
- Sensor and module evaluation
- Arduino and embedded electronics development
- DIY circuit prototyping
- Electronics repair workshops
- Laboratory electronics experiments
For technicians who need a 30V 5A power supply for PCB repair, the SPPS-H305 provides a practical 150W output range for daily electronics service and testing.
