DC Test Power Supply with Memory
Presets KUAIQU R-SPS3030S 30V 30A
900W for Power Module Testing
Power module testing often requires a stable and adjustable DC input source to evaluate modules under different operating conditions. The KUAIQU R-SPS3030S provides 0–30V adjustable voltage, up to 30A current, and 900W output power, giving engineers a high-current DC source for power module development, input condition testing, prototype evaluation, and repeated laboratory testing.
For repeated tests, the M1-M3 memory presets can store frequently used output settings, while the four-digit display provides real-time voltage, current, and power readings during testing. OCP, OVP, output ON/OFF control, and panel lock further support controlled and repeatable power module test setups.
Key Features
30V 30A 900W DC Test Power Supply
The R-SPS3030S provides a 0–30V adjustable output with up to 30A current and 900W maximum power. This output range provides the DC input conditions needed for a wide range of power module testing tasks within the rated operating range.
Adjustable DC Input Conditions for Power Modules
Power modules may need to be evaluated under different DC input conditions during development and verification. Adjustable voltage and current settings allow the R-SPS3030S to provide different test conditions without changing the DC power source.
High Current Output for Module Testing
With up to 30A output current and 900W power, the R-SPS3030S is designed for power module tests that require more current than typical low-power laboratory supplies. The available output capacity supports higher-current module evaluation within the rated specifications.
Real-Time Voltage, Current, and Power Display
The four-digit display shows voltage, current, and power during operation. This allows users to observe the actual electrical conditions of the module input while adjusting or repeating a test setup.
Memory Presets for Repeated Module Tests
M1-M3 memory presets provide three groups of stored settings. Frequently used voltage and current conditions can be recalled when repeating power module tests, reducing repeated manual adjustment between test conditions.
Precision Encoder Adjustment
The precision encoder provides controlled adjustment of voltage and current settings. This is useful when test conditions need to be changed gradually during power module evaluation.
OCP and OVP Protection
Over Current Protection and Over Voltage Protection help protect the power supply and connected test setup when abnormal current or voltage conditions occur. These protection functions provide an additional layer of control during power module testing.
Output ON/OFF Control
The independent output ON/OFF control allows users to start or stop DC output without repeatedly changing the configured voltage and current settings. This is useful when connecting, adjusting, or repeating power module test conditions.
Panel Lock for Consistent Test Settings
The panel lock function helps prevent unintended changes to the configured parameters during testing. This is particularly useful when a power module is being evaluated under a fixed test condition.
Front and Rear Output Connections
The R-SPS3030S provides front and rear output connections for different laboratory setups. The front panel is limited to applications below 5A, while the rear output can be used for the unit's full rated output.
USB and Optional RS232/RS485 Communication Interfaces
The power supply includes a standard USB port, with RS232/RS485 available as optional communication interfaces. These interfaces provide connectivity options for compatible test environments and equipment setups.
Applications
Power Module Input Testing
Provide adjustable DC input conditions for evaluating how a power module operates under different voltage and current settings within the rated output range.
Power Module Operating Condition Testing
Use different voltage and current settings to examine module operation under multiple defined DC input conditions during development and laboratory testing.
Power Module Prototype Evaluation
Provide a controllable DC source for early-stage power module prototypes, allowing engineers to adjust input conditions while monitoring voltage, current, and power.
Power Converter Module Testing
The 30V 30A 900W output capacity can be used as a DC input source for testing power converter modules that require higher current during evaluation.
High Current Power Module Testing
The up to 30A output capability provides a suitable DC source for power module tests that require higher current within the power supply's rated operating range.
Power Module Performance Verification
Monitor voltage, current, and power during testing to verify module behavior under selected DC input conditions.
Power Module Protection Testing
Use adjustable output settings together with OCP and OVP functions when evaluating module test setups that require controlled voltage and current conditions.
Power Module Design Validation
Support repeated laboratory tests during power module development by providing adjustable DC output and stored test settings through M1-M3 memory presets.
Repeated Power Module Testing
Store frequently used test conditions in M1-M3 memory presets and recall them when repeating the same power module evaluation procedure.
Laboratory Power Module Testing
The adjustable output, four-digit monitoring display, protection functions, output control, and panel lock make the R-SPS3030S suitable for laboratory and engineering bench setups focused on power module testing.

Why Choose KUAIQU R-SPS3030S?
The KUAIQU R-SPS3030S is designed around the practical requirements of higher-current power module testing rather than simply providing a high-power DC output. Its 0–30V, 0–30A, 900W capability allows engineers to establish different DC input conditions for module evaluation, while the four-digit display provides direct visibility of voltage, current, and power during testing.
For repeated development and verification work, M1-M3 memory presets help retain frequently used test settings. Precision encoder adjustment provides controlled parameter changes, while OCP, OVP, output ON/OFF control, and panel lock help maintain a more controlled test setup.
With front and rear output connections, standard USB connectivity, optional RS232/RS485 communication interfaces, and a high-current 900W output capacity, the R-SPS3030S can serve as a flexible DC test power source for power module development, evaluation, verification, and repeated laboratory testing.
