The KUAIQU R-SPS3030C 30V 30A 900W DC Supply is a high-current adjustable power supply designed for High Current DC Motor Testing, motor evaluation, actuator testing, and other high-current DC applications.
With an adjustable output range of 0–30V and up to 30A, together with a maximum output power of 900W, this DC Supply provides adjustable DC power for evaluating compatible DC motors under different voltage and current conditions.
The R-SPS3030C features OCP (Over Current Protection), precision encoder adjustment, M1–M3 memory presets, a 4-digit voltage/current/power display, and front and rear dual output ports. These functions provide practical control and monitoring when testing motors that require higher current during operation.
The R-SPS3030C provides adjustable 0–30V voltage and up to 30A current, with a maximum output power of 900W.
For High Current DC Motor Testing, different motors and operating conditions may require different supply parameters. The adjustable output allows users to configure voltage and current according to the requirements of the compatible motor under test.
The 30A high-current capability and 900W maximum output make the R-SPS3030C suitable for testing compatible DC motors and other high-current DC loads within its rated specifications.
DC motors can require different amounts of current under different operating conditions. The R-SPS3030C provides up to 30A output current, allowing users to configure a suitable current level for compatible motor testing applications.
The adjustable voltage output also allows users to change the supplied voltage within the 0–30V range when evaluating motor operation under different power conditions.
This provides a controllable DC source for observing motor behavior during development, evaluation, and testing.
The R-SPS3030C includes OCP (Over Current Protection) to provide an additional protection function when excessive current conditions occur.
During High Current DC Motor Testing, current conditions may change as the motor operates under different test conditions. OCP helps provide protection for the power supply and connected equipment when excessive output current occurs.
This function provides additional support when performing controlled high-current motor testing within the rated output range.
The R-SPS3030C uses a precision encoder for voltage and current adjustment.
During motor testing, users may need to change the supplied voltage or current to evaluate motor response under different operating conditions. The encoder allows controlled adjustment of these parameters within the rated 0–30V and 0–30A output range.
This makes it easier to configure different test points during motor development and evaluation.
The R-SPS3030C features a 4-digit display for monitoring voltage, current, and power during operation.
When performing DC Motor Testing, users can observe the supplied voltage, output current, and power while the motor is operating.
Real-time parameter visibility helps users compare operating conditions and monitor changes in power consumption during different motor test procedures.
The R-SPS3030C provides M1–M3, 3 groups of memory function, allowing users to save frequently used voltage and current settings.
Motor testing may involve repeatedly checking a motor at several predefined power conditions. The memory function allows commonly used settings to be stored and recalled, reducing repeated manual adjustment between test conditions.
This can make repeated motor evaluation and comparison more convenient.
The R-SPS3030C provides both front-panel and rear-panel output ports for different testing setups.
The front-panel output supports loads below 5A, making it suitable for convenient lower-current testing and setup work. The rear output can be used at full rated power, providing access to the complete 900W output capability when higher-current motor testing is required.
For High Current DC Motor Testing, the rear output provides a suitable connection option for applications requiring higher current within the rated specifications.
The Panel Lock Button helps prevent unintended changes to voltage and current settings after the required motor test parameters have been configured.
This can be useful when the power supply is used for repeated or extended motor testing where stable parameter settings are required.
The control knob also includes a buzzer, which can be set to mute according to user preference during testing operations.
The R-SPS3030C is designed to provide adjustable DC power for High Current DC Motor Testing.
Its 0–30V voltage range, up to 30A current output, and 900W maximum power provide the output capability needed for compatible motors requiring higher current during testing.
The precision encoder, 4-digit display, OCP, and adjustable output allow users to configure and monitor motor test conditions within the rated output range.
The DC Supply can be used to evaluate compatible DC motors under different supply voltage and current conditions.
Users can adjust the output voltage and current and monitor the corresponding voltage, current, and power information through the 4-digit display while the motor is operating.
This allows different operating points to be compared during motor evaluation.
The R-SPS3030C provides adjustable DC power for testing compatible motors under different starting and operating conditions.
The high-current 30A output capability provides suitable output capacity for compatible motor applications that require higher current, while OCP provides an additional protection function during testing.
The adjustable output allows users to configure different supply conditions within the rated specifications.
In addition to DC Motor Testing, the R-SPS3030C can provide adjustable power for compatible DC-powered fans, actuators, and other high-current DC equipment.
The 0–30V / 0–30A / 900W output capability provides flexible power adjustment for compatible applications, while the 4-digit display allows users to monitor voltage, current, and power during operation.
Package includes: DC Power Supply ×1, Output Power Cord ×1, Input Power Cord ×1, User Manual ×1, Warranty Card ×1.
Has passed CE & FCC Certification.
All DC power supplies and accessories are inspected before shipment to ensure good quality.
