KUAIQU High Current 30V 30A 900W
R-SPS3030S DC Power Supply with OCP
OVP for Power Electronics Testing
The KUAIQU R-SPS3030S is a High Current 30V 30A 900W DC Power Supply designed for High Current Power Electronics Testing, power module evaluation, high-current DC circuit testing, and laboratory power electronics development. With a 0–30V adjustable output, up to 30A current, and 900W maximum power, it provides a high-current DC source for compatible power electronics circuits and equipment operating within the rated range.
High-current power electronics testing often requires more than simply supplying a fixed DC voltage. Engineers may need to adjust the input voltage, control the current limit, observe actual power consumption, and repeat specific supply conditions while evaluating circuits or modules. The R-SPS3030S combines adjustable voltage and current output with real-time voltage, current, and power display, precision encoder adjustment, OCP and OVP, Output ON/OFF control, M1-M3 memory, and panel lock.
The 30A current capability and 900W output power provide additional capacity for power electronics test setups that require higher-current DC input conditions. The power supply can be used during circuit development, module evaluation, prototype testing, and repeated laboratory testing without adding unsupported specialized test functions.
Key Features
30V 30A 900W High Current DC Power Supply
The R-SPS3030S delivers 0–30V adjustable voltage, up to 30A current, and 900W maximum output power. This high-current capability makes it suitable for power electronics test setups where the required DC input current is higher than that of conventional low-current bench supplies.
The 900W capacity also provides additional operating range when testing compatible power circuits and modules within the specified voltage and current limits.
High Current Output for Power Electronics Testing
The core requirement of many high-current power electronics tests is a controllable DC input source. The R-SPS3030S allows users to adjust both voltage and current according to the requirements of the connected test circuit.
This makes it suitable for establishing different DC input conditions during power electronics development, module evaluation, and bench testing.
Real-Time Voltage, Current and Power Display
The four-digit display provides readback of output voltage, current, and power, allowing users to monitor the electrical condition of the test setup while it is operating.
For high-current testing, power monitoring is particularly useful because increasing current can significantly change the total power delivered to the connected circuit. The display provides direct information without requiring a separate basic measurement for these output values.
Precision Encoder Adjustment
The precision encoder provides convenient control when adjusting voltage and current settings.
During power electronics testing, users can change the supply condition directly from the front panel when moving between different test points or evaluating a circuit under different DC input conditions.
OCP Protection for High Current Testing
The built-in Over Current Protection (OCP) provides an additional protection function for high-current test conditions.
When testing power electronics circuits that can draw substantial current, controlling the current condition is important. OCP helps protect the power supply and connected equipment when an over-current condition occurs.
OVP Protection for Controlled DC Testing
The built-in Over Voltage Protection (OVP) provides protection against abnormal voltage conditions.
For power electronics testing, OVP is useful when the connected circuit has a defined voltage operating range and the power supply is being adjusted during development or evaluation.
Output ON/OFF Control
The Output ON/OFF function allows users to control power delivery without repeatedly disconnecting the test wiring.
This is useful when preparing a power electronics test, changing test connections, or repeating an evaluation. The required voltage and current settings can be configured before output is enabled.
M1-M3 Memory for Repeated Test Conditions
The R-SPS3030S provides three memory groups, M1-M3, for storing commonly used settings.
When power electronics testing involves repeated test conditions, saved settings can reduce repeated manual adjustment and make recurring bench tests more convenient.
Panel Lock for Stable Test Settings
The panel lock function helps prevent unintended changes to the configured power supply parameters during testing.
After the required voltage and current settings have been established, users can lock the panel to help maintain the intended test condition while evaluating the connected circuit or module.
USB and RS232 RS485 Communication Interfaces
The R-SPS3030S provides a USB interface, while RS232 and RS485 are available as optional communication interfaces.
These interfaces provide communication options for compatible testing environments and equipment setups where communication with the DC power supply is required. The communication interfaces do not change the primary function of the product as a high-current DC power supply.
Applications
High Current Power Electronics Testing
The R-SPS3030S is designed for High Current Power Electronics Testing where the test setup requires adjustable DC power up to 30V and 30A. The 900W maximum output provides additional power capacity for compatible power electronics circuits and modules.

Power modules may require different DC input conditions during development and evaluation. The R-SPS3030S provides adjustable voltage and current so users can establish appropriate supply conditions within the module's rated operating range.
Power Electronics Prototype Testing
During prototype development, engineers may need to change the DC input condition while evaluating a new power electronics design. The R-SPS3030S provides adjustable output, precision encoder control, and voltage, current, and power readback for this type of bench testing.
High Current DC Input Testing
The R-SPS3030S can be used as a high-current DC source when evaluating compatible equipment that requires a higher-current input. Its 0–30V and up to 30A output range allows users to configure different DC input conditions within the rated specifications.
Power Conversion Circuit Testing
The adjustable DC output can provide input power for compatible power conversion circuits during development and evaluation. The 900W maximum output gives the test setup additional power capacity when higher-current DC input conditions are required.
Power Electronics Circuit Development
During circuit development, engineers can adjust voltage and current to establish different operating conditions for compatible power electronics circuits. The precision encoder and Output ON/OFF control provide convenient front-panel operation during iterative testing.
Repeated Power Electronics Testing
For repeated tests using the same power conditions, the M1-M3 memory function provides three groups of stored settings. This helps reduce repeated parameter adjustment when performing similar power electronics evaluations.
Laboratory High Current DC Testing
The R-SPS3030S can serve as a High Current DC Power Supply for laboratory testing of compatible power electronics circuits, modules, and DC-powered equipment within the 0–30V, 0–30A, and 900W output range.
Power Electronics Equipment Evaluation
The combination of adjustable DC output, high-current capability, OCP, OVP, output control, and real-time power readback makes the R-SPS3030S suitable for evaluating compatible power electronics equipment during development and bench testing.
