Adjustable DC Power Supply and Bench
Supply with Encoder for DC-DC Converter
Testing
The KUAIQU R-SPS3020S is a 0–30V 0–20A 600W adjustable DC power supply and bench supply designed for DC-DC converter testing, power conversion circuit development, prototype evaluation, and laboratory testing. Its adjustable DC output allows users to establish different input voltage and current conditions for compatible DC-DC converter test setups within the rated output range.
For DC-DC converter testing, controlled input conditions and clear electrical parameter monitoring are important when evaluating converter behavior under different supply settings. The R-SPS3020S combines adjustable voltage and current output with a precision encoder, four-digit voltage/current/power display, OVP and OCP protection, output ON/OFF control, M1-M3 memory, and panel lock. These functions provide practical control and monitoring for repeated bench testing without adding unsupported automated test or waveform-generation functions.
Key Features
0-30V 0-20A 600W Adjustable DC Power Supply
The R-SPS3020S provides an adjustable 0–30V DC output, up to 20A current, and 600W maximum power. This output range provides flexible DC input conditions for compatible DC-DC converters and power conversion circuits during laboratory and bench testing.
The available voltage and current range allows users to configure different test conditions according to the input requirements of the converter under test, while remaining within the rated output capability of the power supply.
Bench Supply for DC-DC Converter Testing
As an adjustable bench supply, the R-SPS3020S can provide the DC input source required by compatible DC-DC converter test circuits.
Users can adjust the supply voltage and current according to the intended test condition and observe the resulting voltage, current, and power readings while the converter is connected.
Precision Encoder for Voltage and Current Adjustment
The precision encoder provides convenient adjustment of the voltage and current settings. The voltage setting resolution is 10mV and the current setting resolution is 10mA.
This allows users to make controlled changes to the DC input condition when comparing a converter's operation at different supply settings.
Four-Digit Display for Voltage, Current, and Power
The four-digit display provides voltage, current, and power readings during operation.
For DC-DC converter testing, these readings allow users to observe the electrical conditions at the power supply output while adjusting the input parameters for the converter test setup.
OVP and OCP Protection
The R-SPS3020S provides Over Voltage Protection and Over Current Protection.
These protection functions can help provide an additional level of protection when abnormal voltage or current conditions occur during testing. This is useful when different converter prototypes or test circuits are connected to the same adjustable DC power supply.
Output ON/OFF Control
The output ON/OFF function allows users to enable or disable the DC output without changing the configured voltage and current settings.
This provides a convenient way to prepare the required input parameters before applying power to a DC-DC converter and to remove output power when changing the test connection.
M1-M3 Memory for Repeated Converter Tests
The R-SPS3020S provides three memory groups, M1-M3, for storing commonly used settings.
When DC-DC converter testing requires repeated use of the same input voltage and current conditions, stored settings can be recalled for more convenient configuration and more consistent repeated test setups.
Panel Lock for Stable Test Settings
The panel lock function helps prevent accidental changes to the configured voltage and current settings during operation.
This can be useful when testing several converter samples under the same input conditions and helps maintain the selected power supply settings during a test.
Front and Rear Output Connections
The R-SPS3020S provides front and rear output ports for different bench and test-system arrangements.
The front panel output is intended for currents below 5A, while the rear output can be used when operating at the full rated power. Users can select the appropriate output connection according to the current requirement and physical layout of the DC-DC converter test setup.
USB and Optional RS232/RS485 Communication Interfaces
The R-SPS3020S provides a standard USB interface, with RS232/RS485 available as applicable options.
These communication interfaces provide additional connection possibilities for compatible external systems. The actual interface configuration should be selected according to the product version and requirements of the connected system.
Applications
DC-DC Converter Testing
The R-SPS3020S can provide adjustable DC input power for compatible DC-DC converters. Users can change the input voltage and current settings within the 0–30V and 0–20A output range while monitoring the power supply readings during testing.
DC-DC Converter Prototype Evaluation
During converter development, engineers may need to evaluate a prototype under different DC input conditions.
The adjustable DC power supply allows users to establish different input voltage and current settings and observe the corresponding output conditions of the converter through their test instruments.
Power Conversion Circuit Testing
The R-SPS3020S can be used as an adjustable DC source for compatible power conversion circuits.
Its 600W maximum output provides a practical power range for bench testing of low-voltage power conversion circuits that fall within the supply's rated specifications.
Converter Input Condition Testing
Different converter designs can require different input voltage conditions. The adjustable 0–30V output allows users to configure the DC input condition according to the requirements of the converter test.
The precision encoder and four-digit display make it convenient to adjust and monitor the selected supply parameters.
DC-DC Converter Development
During circuit development, the R-SPS3020S can provide adjustable bench power for compatible converter prototypes and development boards.
The user can modify voltage and current settings as the circuit design and test requirements change.
Power Module Testing
The 0–30V, 0–20A, 600W output capability can be used to provide DC input power for compatible power modules and conversion modules during development and evaluation.
The actual test conditions should remain within the voltage, current, and power specifications of both the power supply and the device under test.
Converter PCB Testing
The R-SPS3020S can provide adjustable DC power for compatible PCB-based DC-DC converter test setups.
Output ON/OFF control allows users to control when DC power is applied, while the display provides voltage, current, and power readings during operation.
Repeated DC-DC Converter Testing
M1-M3 memory provides three groups for commonly used power supply settings.
For repeated converter tests using the same input conditions, stored settings can reduce repeated manual adjustment and help users maintain consistent power supply configurations between test runs.
Laboratory Power Conversion Experiments
The R-SPS3020S can serve as a bench supply for laboratory experiments involving compatible DC-DC converters, power conversion circuits, and electronic prototypes.
The adjustable output and real-time voltage, current, and power display provide practical control and monitoring during bench testing.
DC Input Testing for Electronic Modules
The adjustable DC output can provide the input power for compatible electronic modules that require a controlled DC source within the R-SPS3020S rated range.
The OVP, OCP, output ON/OFF control, and panel lock functions provide additional practical controls when configuring and operating the test setup.
