KUAIQU SPPS-K305R-4KD 30V 5A 4-Channel DC Power Supply for PCB Testing
KUAIQU SPPS-K305R-4KD 30V 5A 4-Channel DC Power Supply Product Overview The KUAIQU SPPS-K305R-4KD is a professional 30V 5A 4-channel DC power supply designed for PCB testing, electronics prototyping, circuit debugging, and laboratory R&D. Each of the four independent channels provides 0–30V and 0–5A adjustable output, allowing engineers to power multiple circuits, boards, or voltage rails simultaneously. Featuring a modular 4U chassis, the power supply units can be pulled out and removed for standalone operation, providing a flexible solution for both centralized multi-channel testing and individual bench testing. With precise regulation, low ripple and noise, independent output control, preset data storage, and multiple communication interfaces, the SPPS-K305 is a versatile multi-channel DC power supply for electronics R&D. Key Features 4-Channel Independent Output: Each channel provides 0–30V/0–5A adjustable output, making this 30V 5A 4-channel DC power supply suitable for powering multiple PCBs, modules, sensors, and electronic circuits at the same time. Modular 4U Pull-Out Design: The modular 4U power supply chassis allows individual power supply units to be pulled out and used independently. This 4U modular DC power supply can therefore adapt to centralized multi-channel testing or separate test benches. Independent Output ON/OFF Control: Each channel has a dedicated output switch, allowing users to activate or disconnect individual outputs without affecting the other channels. Simultaneous Multi-Channel Display: The LED display provides simultaneous monitoring of voltage, current, and power across the four channels for convenient multi-output testing. Precise CV/CC Regulation: Continuous voltage and current adjustment with automatic switching between constant voltage and constant current modes provides stable power for PCB testing and circuit debugging. Low Ripple & Low Noise: Clean and stable DC output helps provide reliable operating conditions for sensitive circuits, sensors, development boards, and precision electronic components. OVP & OCP Protection: Each output features Over Voltage Protection (OVP) and Over Current Protection (OCP) to help protect connected devices and the power supply during abnormal conditions. 3 Groups of Preset Data: Three groups of output settings can be stored and recalled, making repetitive electronics testing and R&D more efficient. USB / RS232 / RS485 Communication: Multiple communication interfaces support external control and integration with automated laboratory or testing systems. USB-A & USB-C Charging: Built-in USB-A and USB-C ports provide convenient auxiliary charging for compatible electronic devices and testing accessories. Intelligent Temperature Control: The temperature-controlled fan automatically adjusts cooling according to operating conditions, helping maintain stable performance while reducing unnecessary fan noise. Application Scenarios The SPPS-K305 is optimized for low-voltage multi-channel applications where 30V/5A output is sufficient and multiple independent power sources are required. PCB Testing & Debugging The SPPS-K305 works as a 4-channel DC power supply for PCB testing, providing independent adjustable outputs for different circuit sections, boards, and voltage rails. It is suitable for PCB development, troubleshooting, and board-level debugging. Electronics R&D & Prototyping As a 30V 5A multi-output power supply, it provides flexible power for electronic prototypes, development boards, sensors, embedded systems, and control circuits. Laboratory Testing The four independent channels make it suitable as a 4-channel bench power supply for electronics testing, allowing multiple devices or experimental circuits to operate simultaneously.
