The KUAIQU SPPS-H305 is a 30V 5A 150W DC Bench Power Supply designed for embedded system testing, circuit debugging, prototype development, and engineering verification. With precise voltage/current adjustment, stable DC output, Output ON/OFF control, and built-in OCP/OVP protection, it provides reliable power support for engineers working with microcontrollers, development boards, embedded modules, and electronic prototypes.
The SPPS-H305 adjustable DC bench power supply uses a precision encoder knob for smooth voltage and current adjustment. Engineers can easily set suitable power conditions when testing embedded boards, control modules, sensors, and prototype circuits, helping verify system performance under different operating requirements.
Designed as a regulated DC bench power supply, the SPPS-H305 provides stable and clean DC output with low ripple performance. This helps reduce power interference during embedded system testing and supports reliable evaluation of microcontrollers, development boards, communication modules, and other sensitive electronic components.
The dedicated Output ON/OFF function allows users to control power delivery without changing the preset voltage and current settings. This is useful for repeated embedded system testing, prototype debugging, and quick power cycling during development processes.
The SPPS-H305 features built-in Over Current Protection (OCP) and Over Voltage Protection (OVP). These protection functions help protect connected embedded systems, test circuits, and electronic components from unexpected over-current or over-voltage conditions during testing.
The integrated USB 5V/2A output provides convenient power support for compatible USB devices during development and testing, such as development accessories, cooling fans, and other low-power auxiliary equipment.
The clear LED display provides real-time monitoring of:
Output Voltage (V)
Output Current (A)
Output Power (W)
Engineers can quickly check operating conditions while debugging embedded systems and verifying circuit behavior.
The SPPS-H305 30V 5A 150W DC Bench Power Supply is suitable for embedded system engineers working on hardware development, prototype verification, and functional testing. Its adjustable output and stable performance support testing of embedded controllers, development boards, and electronic modules.
With precise voltage and current adjustment, the power supply helps engineers evaluate microcontroller-based systems, embedded platforms, and prototype circuits under different power conditions.
The adjustable DC output and Output ON/OFF control make it convenient for repeated testing during circuit debugging, allowing engineers to quickly switch power states while maintaining preset parameters.
The SPPS-H305 provides reliable power for testing embedded modules, communication units, sensors, and low-power control systems where stable DC power is required.
