DC Test Power Supply KUAIQU 15V 30A
450W R-SPS1530S with 4-Digit Display
for Electronic Component Testing
The KUAIQU R-SPS1530S is a high-power DC test power supply designed for electronic component testing, circuit development, prototype verification, and laboratory bench work. With adjustable 0–15V output, up to 30A current, and 450W power capacity, it provides flexible DC power for testing electronic components and low-voltage circuits under different operating conditions. The 4-digit display provides clear real-time voltage, current, and power readings, while OCP, OVP, output ON/OFF control, and panel lock help support controlled and repeatable testing workflows.
Key Features
15V 30A 450W DC Test Power Supply
The R-SPS1530S provides an adjustable 0–15V DC output with up to 30A current and 450W maximum power. This high-current output gives electronic component testing setups sufficient power flexibility for different low-voltage devices, components, and test circuits.
4-Digit Display for Real-Time Test Monitoring
The 4-digit display shows voltage, current, and power readings clearly during operation. This allows users to monitor the electrical conditions of the connected test circuit without relying on external displays.
Precision Encoder Adjustment
The precision encoder provides controlled adjustment of voltage and current settings. The 10mV voltage setting resolution and 10mA current setting resolution support detailed parameter adjustment during electronic component testing.
OCP and OVP Protection
Built-in Over Current Protection and Over Voltage Protection help protect the power supply and connected test equipment when abnormal current or voltage conditions occur. These protection functions are useful when working with sensitive electronic components and experimental circuits.
Output ON/OFF Control
The dedicated output control allows users to enable or disable DC output separately from the main power operation. This makes it easier to prepare voltage and current settings before applying power to the test circuit.
M1-M3 Memory for Repeated Testing
Three memory groups, M1-M3, can store commonly used power supply settings for quick recall. This can simplify repeated electronic component testing when the same voltage and current conditions are used across multiple test samples.
Panel Lock for Stable Test Settings
The panel lock function helps prevent accidental changes to voltage or current settings during operation. It is useful when a test requires stable parameters across multiple components or repeated test cycles.
Front and Rear Output Connections
The R-SPS1530S provides front and rear output ports for flexible connection arrangements. The front panel output is intended for currents below 5A, while the rear output can be used when operating at the full rated output.
USB and Optional RS232/RS485 Communication Interfaces
The series provides a standard USB interface, with RS232/RS485 available as applicable options. These interfaces can support connection with external control systems where the corresponding interface configuration is provided.
Applications
Electronic Component Testing
Provides adjustable DC power for electronic component testing setups where controlled voltage and current conditions are required for component evaluation.
Resistor and Passive Component Testing
Supports DC power requirements for test circuits involving resistors and other passive components, allowing users to apply adjustable operating conditions within the 0–15V and 0–30A output range.
Diode and Semiconductor Component Testing
Can provide controlled DC input power for test circuits containing diodes and other semiconductor components, with voltage and current monitoring available through the built-in display.
Transistor and Electronic Device Testing
Provides adjustable DC power for transistor-related test circuits and low-voltage electronic devices where controlled power input and real-time electrical readings are required.
IC and Chip Circuit Testing
Suitable as a DC power source for IC evaluation boards, chip-related test circuits, and other low-voltage electronic development setups within the power supply's output range.
PCB and Circuit Testing
Provides adjustable DC power for PCB prototypes and electronic circuits during development, troubleshooting, and functional verification.
Electronic Prototype Evaluation
The adjustable output and memory settings support repeated power conditions during electronic prototype development and early-stage testing.
Laboratory Electronic Testing
The R-SPS1530S can serve as a bench DC test power supply for laboratory experiments involving electronic components, circuits, and low-voltage devices.
Repeated Component Test Conditions
M1-M3 memory settings can help users quickly recall frequently used voltage and current parameters when testing multiple components under similar conditions.
