KUAIQU PCB Board Debugging DC Bench
Power Supply DC Source SPPS305-2KD
30V 5A 150W×2 with OCP and OVP
The KUAIQU SPPS305-2KD is a DC Bench Power Supply and DC Source designed for PCB Board Debugging, circuit development, electronic module testing, and laboratory troubleshooting. It provides two independent adjustable output channels, with each channel supporting 0-30V and 0-5A output and 150W power, allowing engineers, technicians, and students to supply different sections of a PCB during debugging and testing.
For PCB Board Debugging, different circuit sections may require separate power conditions during development and troubleshooting. The SPPS305-2KD supports independent dual-channel operation as well as one-key series and parallel output modes, giving users flexible voltage and current configurations from one DC Bench Power Supply. OCP and OVP protection, dedicated Output ON/OFF control, precision encoder adjustment, and memory functions provide practical control for repeated PCB testing and debugging work.
Key Features
Dual Independent Outputs for PCB Board Debugging
The SPPS305-2KD provides two independent DC output channels, with each channel supporting 0-30V, 0-5A, and 150W output.
During PCB Board Debugging, CH1 and CH2 can be adjusted independently to provide separate DC power conditions for different parts of a test setup. This is useful when a PCB debugging task requires separate power sources for different circuit sections or connected electronic modules.
One-Key Series and Parallel Output
The SPPS305-2KD supports independent, series, and parallel output configurations, allowing the DC Source to adapt to different PCB testing requirements.
In series mode, the two channels can provide up to 0-60V and 0-5A. In parallel mode, they can provide up to 0-30V and 0-10A. The dedicated series and parallel output port avoids complicated wiring when changing the output configuration, making it easier to adjust the power setup during PCB Board Debugging.
OCP and OVP Protection for PCB Testing
The SPPS305-2KD provides Over Current Protection and Over Voltage Protection for the dual channels, series mode, and parallel mode.
During PCB Board Debugging, incorrect voltage or current settings can damage sensitive electronic circuits. OCP and OVP help protect the DC Bench Power Supply and connected loads by turning off the output when the corresponding protection condition is triggered.
Precision Encoder Adjustment
The SPPS305-2KD uses encoder adjustment for voltage and current control, allowing users to make controlled output adjustments during PCB Board Debugging.
The 10mV voltage setting resolution and 1mA current setting resolution provide fine adjustment within the specified output range. This is useful when debugging a PCB where the supply voltage or current limit needs to be adjusted according to the circuit under test.
Output ON/OFF Control and 8-Group Memory
The SPPS305-2KD provides dedicated Output ON/OFF control and 8 groups of memory for independent, series, and parallel operating modes.
During repeated PCB Board Debugging tasks, commonly used voltage and current settings can be stored and recalled. The Output ON/OFF function also allows users to control the DC output without repeatedly changing the configured voltage and current settings.
Panel Lock and Negative-0-Positive Voltage Output
The SPPS305-2KD includes a Panel Lock function with buzzer and supports negative voltage-0-positive voltage output mode.
The panel lock can help prevent unintended changes to settings during PCB testing, while the negative voltage-0-positive voltage output mode provides an additional power configuration for circuit boards and electronic circuits that require bipolar supply conditions.
Applications
PCB Board Debugging
The SPPS305-2KD is designed to provide adjustable DC power during PCB Board Debugging, allowing users to establish controlled voltage and current conditions while checking circuit operation.
The two independent output channels can be used to supply different sections of a PCB or related electronic modules, while OCP and OVP provide protection during debugging work.
Circuit Section Power Testing
Different sections of a PCB may require different supply conditions during development and troubleshooting.
With two independent adjustable channels, the SPPS305-2KD can provide separate output settings for different circuit sections. Series and parallel modes can also be selected when a debugging task requires a different voltage or current configuration.
Electronic Module Debugging
The SPPS305-2KD can be used as a DC Source for debugging electronic modules connected to a PCB.
The adjustable 0-30V and 0-5A output of each independent channel allows users to set the required supply conditions within the product's specified range. Precision encoder adjustment helps users make controlled changes during module testing.
Repeated PCB Testing
For repeated PCB Board Debugging tasks, the 8-group memory function can store commonly used output settings for independent, series, and parallel modes.
Combined with Output ON/OFF control and Panel Lock, the stored settings can help users maintain consistent power configurations when performing repeated debugging and testing work.
