Automotive Electronics Testing KUAIQU
30V 20A 600W R-SPS3020S with OCP
The KUAIQU R-SPS3020S is a 30V 20A 600W regulated DC power supply designed for automotive electronics testing, electronic module evaluation, circuit development, and laboratory bench testing. With an adjustable 0–30V DC output and up to 20A current, it provides a flexible DC power source for compatible automotive electronic devices, modules, development boards, and test circuits within the rated operating range.
Automotive electronics testing often requires controlled DC supply conditions, clear electrical parameter monitoring, and repeatable test settings. The R-SPS3020S combines adjustable voltage and current output with a four-digit display for voltage, current, and power readings. OCP, OVP, output ON/OFF control, precision encoder adjustment, M1-M3 memory, and panel lock provide practical functions for configuring and repeating automotive electronics test conditions without adding unsupported automotive-specific test functions.
Key Features
30V 20A 600W Regulated 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 power for compatible automotive electronic components, modules, development circuits, and other test devices that operate within the supply's rated specifications.
The adjustable output allows users to establish different DC supply conditions for different automotive electronics testing tasks rather than relying on a fixed-voltage source.
Adjustable Voltage and Current for Automotive Electronics Testing
The voltage and current settings can be adjusted according to the requirements of the connected automotive electronics test circuit.
With a voltage setting resolution of 10mV and current setting resolution of 10mA, the R-SPS3020S allows users to make controlled adjustments when establishing different test conditions for compatible automotive electronic devices and circuits.
Four-Digit Display for Voltage, Current, and Power Monitoring
The four-digit display provides voltage, current, and power readings during operation.
For automotive electronics testing, these readings allow users to monitor the electrical conditions at the power supply output while adjusting the supply parameters for a connected test circuit or electronic module.
Precision Encoder Adjustment
The precision encoder provides convenient adjustment of voltage and current settings.
During automotive electronics testing, users can make gradual changes to the DC output while observing the corresponding voltage, current, and power readings on the display. This can be useful when comparing a test circuit under different supply conditions.
OCP and OVP Protection
The R-SPS3020S provides Over Current Protection and Over Voltage Protection.
These protection functions provide additional protection when abnormal current or voltage conditions occur during testing. They are useful when different automotive electronic devices, modules, or prototype 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 allows users to prepare the required test parameters before applying power to an automotive electronics test circuit. The output can also be disabled when changing connections or preparing another test condition.
M1-M3 Memory for Repeated Automotive Electronics Tests
The R-SPS3020S provides three memory groups, M1-M3, for storing commonly used voltage and current settings.
When testing multiple automotive electronic modules or repeating the same test condition, users can recall stored settings instead of manually entering the same parameters each time. This can make repeated bench testing more convenient and help maintain consistent power supply settings.
Panel Lock for Stable Test Parameters
The panel lock function helps prevent accidental changes to the configured voltage and current settings during operation.
This is useful when several automotive electronic samples need to be tested under the same power supply conditions, helping keep the selected parameters stable during repeated testing.
Front and Rear Output Connections
The R-SPS3020S provides front and rear output ports for different test bench configurations.
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 arrangement of the automotive electronics 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 the requirements of the connected test system.
