300V 10A 3000W R-SPS30010S Regulated
DC Voltage Source for Power Conversion
Testing by KUAIQU
The KUAIQU R-SPS30010S is a 300V 10A 3000W Regulated DC Voltage Source developed for Power Conversion Testing. Its 0–300V adjustable DC output provides a controllable input source for evaluating power conversion circuits, DC-DC converters, power modules, and other equipment that requires variable DC input conditions within the rated output range.
The 300V voltage capability makes the R-SPS30010S particularly suitable for test setups where the DC input voltage needs to be adjusted across different conversion operating points. With CC and CV operation, direct voltage, current, and power display, OCP and OVP protection, and four memory groups, users can establish and repeat defined DC input conditions during power conversion evaluation.
Key Features
0-300V Regulated DC Voltage Source for Conversion Testing
The 0–300V adjustable output provides a broad DC voltage range for establishing different input conditions during Power Conversion Testing. This allows compatible conversion equipment to be evaluated at different DC supply voltage settings within the rated range.
3000W Power Capacity for Conversion Equipment
The 3000W output rating provides substantial power capacity for power conversion test setups. It allows the DC Voltage Source to support compatible conversion equipment and power modules operating at higher power levels within the rated voltage and current limits.
10A Output for Controlled Conversion Test Conditions
The adjustable 0–10A current range allows users to establish appropriate current limits for different power conversion test conditions while using the 0–300V voltage range.
CC and CV Operation for Power Conversion Evaluation
CC and CV operation provides two practical output regulation modes. Users can establish constant voltage or controlled current conditions according to the requirements of the connected conversion circuit or equipment.
Adjustable Input Conditions for Conversion Operating Points
The encoder-based voltage and current adjustment allows test operators to change the DC input conditions when evaluating different operating points of compatible power conversion equipment.
OVP for High-Voltage DC Test Conditions
The built-in Over-Voltage Protection provides an additional protection function when working with adjustable DC voltage conditions, particularly during higher-voltage Power Conversion Testing.
OCP for Controlled Current Limits
Over-Current Protection helps manage excessive current conditions during conversion testing and provides additional protection for the power supply and connected test setup.
Direct Voltage, Current, and Power Readback
The four-digit display shows voltage, current, and power values directly, allowing users to observe the electrical conditions supplied to the equipment under test.
M1-M4 Memory for Repeated Conversion Conditions
Four memory groups, M1-M4, provide storage for frequently used voltage and current settings. This is useful when a power conversion test requires the same DC input conditions to be established repeatedly.
Output ON/OFF for Controlled Power Application
The Output ON/OFF function allows users to apply or remove DC output from the connected conversion equipment without changing the stored voltage and current settings.
Panel Lock for Fixed Conversion Test Settings
Once the required voltage and current conditions have been established, the Panel Lock function helps prevent unintended changes to the test parameters during operation.
Rear Output for High-Power Conversion Test Setups
The rear output connection provides a practical connection point for power conversion applications and supports use of the R-SPS30010S in higher-power test configurations.
USB, RS232, and RS485 Communication Interfaces
The R-SPS30010S is equipped with USB, RS232, and RS485 communication interfaces for compatible external communication or control applications. The available control functions depend on the connected system and supported interface configuration.
