DC Motor Testing with High Power
KUAIQU 0-30V 0-30A 900W R-SPS3030S
Bench Power Supply with CC CV
The KUAIQU R-SPS3030S is a 0-30V 0-30A 900W High Power Bench Power Supply designed for DC Motor Testing, motor development, motor drive circuit evaluation, and laboratory bench testing. Its adjustable 0-30V output and up to 30A current capability provide a flexible DC power source for compatible DC motors, motor circuits, and related test equipment operating within the rated specifications.
DC motor testing often requires controlled changes to the motor's DC supply conditions while observing the resulting voltage, current, and power. The R-SPS3030S provides adjustable voltage and current control, allowing users to establish different supply conditions during motor testing. Its four-digit display provides voltage, current, and power readback, while the precision encoder, OCP, OVP, Output ON/OFF control, M1-M3 memory, and panel lock provide practical functions for repeated motor test work.
With up to 30A current and 900W output power, the R-SPS3030S provides additional power capacity for compatible DC motor test setups that require higher current during startup, operating-condition evaluation, or repeated bench testing.
Key Features
0-30V 0-30A 900W High Power Bench Power Supply
The R-SPS3030S provides 0-30V adjustable output, up to 30A current, and 900W maximum power for compatible DC motor testing applications.
The high-current output provides greater capacity for motor test setups that require higher DC input current, while the adjustable voltage allows users to establish different supply conditions according to the motor or test circuit requirements.
Adjustable DC Output for DC Motor Testing
DC motors can be evaluated under different supply voltage and current conditions. The R-SPS3030S allows users to adjust the output according to the requirements of the motor and test setup within the rated range.
This makes the power supply suitable for bench testing during motor development, evaluation, and troubleshooting.
CC CV Control for Motor Test Conditions
The CC CV operating characteristics allow the power supply to regulate the output according to the configured voltage and current conditions.
During DC motor testing, this provides a controllable DC source for establishing test conditions and observing changes in the motor's electrical operating parameters.
Voltage, Current and Power Display
The four-digit display provides readback of voltage, current, and power during operation.
When testing a DC motor, these values allow users to monitor the electrical input condition while changing the supply settings or evaluating the motor under different operating conditions.
Precision Encoder Adjustment
The precision encoder provides convenient adjustment of voltage and current settings.
For DC motor testing, users can adjust the supply parameters directly from the front panel when moving between different test conditions or evaluating how the motor responds to changes in its DC supply.
OCP Protection for Motor Testing
The built-in Over Current Protection (OCP) provides an additional protection function when testing DC motors and related circuits.
Because motor test conditions can involve changes in current, OCP helps provide protection when an over-current condition occurs during testing.
OVP Protection for Controlled DC Output
The built-in Over Voltage Protection (OVP) helps protect the test setup against abnormal voltage conditions.
This is useful when the DC output is being adjusted during motor development or testing and the connected motor or circuit has a defined voltage operating range.
Output ON/OFF Control
The Output ON/OFF function allows users to control power delivery to the motor test setup without repeatedly disconnecting the output wiring.
Users can prepare the required voltage and current settings before enabling the output, providing a convenient way to start or stop the DC motor test.
M1-M3 Memory for Repeated Motor Tests
The R-SPS3030S provides three memory groups, M1-M3, for storing commonly used power supply settings.
When the same DC motor or test circuit is evaluated repeatedly, saved settings can reduce repeated manual adjustment and make recurring test conditions more convenient to reproduce.
Panel Lock and Front Rear Output Connections
The panel lock function helps prevent unintended changes to the configured settings during testing. The R-SPS3030S also provides front and rear output connections, allowing users to select a suitable connection arrangement for different DC motor test bench layouts.
