30V 60A 1800W R-SPS3060S High Current
DC Power Supply for Power Electronics
Testing by KUAIQU
The KUAIQU R-SPS3060S is a 30V 60A 1800W High Current DC Power Supply developed for power electronics test setups that require substantial DC current together with controlled voltage and current adjustment. With a 0–30V adjustable output and up to 60A current capability, it can serve as the DC input source for compatible power modules, power conversion circuits, high-current electronic assemblies, and laboratory development platforms.
In high-current power electronics testing, the power supply is not simply a source of electricity. The test engineer often needs to establish a defined DC input condition, increase or reduce the supplied current, observe actual power consumption, repeat the same operating condition, and prevent accidental changes during a test. The R-SPS3060S combines these requirements through adjustable output, precision encoder adjustment, four-digit voltage/current/power readback, OCP, OVP, Output ON/OFF, M1-M3 memory, and Panel Lock.
The 1800W output rating and 60A current capability also give the R-SPS3060S more room for high-current test arrangements than lower-power bench supplies, while its 0–30V voltage range keeps it suitable for compatible low-voltage and high-current power electronics applications.
Key Features
30V 60A 1800W Output for High Current Testing
The R-SPS3060S provides 0–30V adjustable DC output, up to 60A current, and 1800W maximum output power. This combination is particularly relevant when a power electronics test circuit requires substantial current while remaining within a low-voltage DC operating range.
For engineers evaluating power modules, conversion circuits, and other high-current electronic assemblies, the 60A capacity provides the current capability needed to establish demanding test conditions without moving immediately to a larger industrial DC source.
Adjustable DC Input Conditions
Power electronics devices may need to be evaluated under different supply conditions during development. The R-SPS3060S allows the output voltage and current to be adjusted to establish the required DC input conditions within its rated range.
This makes one power source useful across different stages of circuit development, from initial bench evaluation to repeated operating-condition checks.
High Current Capacity for Power Electronics
The 60A maximum current is one of the defining characteristics of the R-SPS3060S. It allows the supply to support high-current test assemblies where current demand is a more important consideration than simply increasing voltage.
Combined with the 1800W power rating, the supply is suitable for power electronics applications that require a substantial DC power source for development and evaluation.
Four-Digit Readback of Voltage, Current, and Power
The four-digit display provides direct visibility of output voltage, current, and power during testing.
For power electronics evaluation, monitoring these three values together helps the operator understand the actual electrical condition of the connected test circuit while adjusting the DC supply or repeating an established test condition.
Precision Encoder for Controlled Adjustment
The precision encoder provides a practical way to adjust voltage and current settings during bench testing.
Instead of relying on repeated broad adjustments, the encoder allows the operator to establish the desired test parameters more deliberately when evaluating different operating conditions.
OCP and OVP Protection for Test Operation
High-current testing requires attention to abnormal operating conditions. The R-SPS3060S includes Over Current Protection and Over Voltage Protection to help protect the power supply and connected equipment when configured protection conditions are reached.
These protection functions are especially relevant when the supply is connected to development circuits or power electronic assemblies where the test condition may change during evaluation.
Output ON/OFF Control
Output ON/OFF control allows the operator to manage when DC power is applied to the test circuit.
The configured voltage and current settings can remain available while the output is switched off, making the function useful when connecting equipment, preparing a test condition, or repeating a test without unnecessarily resetting the main parameters.
M1-M3 Memory for Repeated Test Conditions
The R-SPS3060S provides three memory groups, M1-M3, for frequently used settings.
For repeated power electronics testing, this can reduce the need to manually recreate the same voltage and current conditions each time. It is particularly useful when a development procedure requires several established test conditions to be revisited.
Panel Lock for Consistent Test Settings
Panel Lock helps prevent unintended adjustment of the configured parameters during testing.
This is useful when a power electronics test needs to continue under a defined voltage and current condition and accidental changes to the front-panel controls should be avoided.
Front and Rear Output Connections
The R-SPS3060S provides front and rear output connections to accommodate different test bench arrangements.
The front connection can be convenient for laboratory bench work, while the rear output provides an alternative connection arrangement for installations where the power supply is integrated into a test setup.
USB/RS232/RS485 Communication Interfaces
The R-SPS-S series supports USB communication, with RS232/RS485 available according to configuration.
These interfaces provide connection options for test environments where the power supply needs to be incorporated into a compatible equipment or communication setup.
Applications

Why Choose KUAIQU R-SPS3060S?
Built Around High Current Power Electronics Requirements
The main value of the R-SPS3060S for this application is not simply that it is a DC power supply. Its 60A current capacity and 1800W power rating are designed for test setups where current demand is an important part of the evaluation.
For compatible power electronics circuits operating within the 0–30V range, the R-SPS3060S provides a substantial DC source without requiring the test engineer to use a separate low-current supply for higher-current development work.
Control the DC Condition, Then Observe the Result
Power electronics testing often requires more than applying a fixed voltage. The operator may need to change the voltage or current condition, observe the resulting current and power, and then establish another test point.
The R-SPS3060S combines adjustable output, precision encoder adjustment, and four-digit voltage/current/power readback to support this workflow directly from the power supply.
Better Suited to Repeated Development Work
Development testing often involves returning to previously established conditions. The M1-M3 memory groups allow three commonly used settings to be stored, while Panel Lock helps keep the selected parameters from being changed accidentally.
This makes the supply practical not only for one-time experiments but also for repeated power electronics evaluation.
Protection for High Current Operation
OCP and OVP provide dedicated protection functions for the DC output. These functions are particularly relevant when the supply is connected to developing power electronic circuits and the operating conditions are being changed during testing.
Flexible for Different Test Bench Arrangements
Front and rear output connections provide flexibility when the power supply is used on a laboratory bench or integrated into a larger test arrangement. USB and optional RS232/RS485 communication interfaces also provide connection options for compatible test environments.
The KUAIQU R-SPS3060S 30V 60A 1800W High Current DC Power Supply therefore fits the role of a high-current DC source for power electronics development, power module evaluation, power conversion circuit testing, and other compatible high-current laboratory test applications.
