KUAIQU 120V DC System Testing DC
Voltage Source DC Power Supply SPPS-
C1203 0-120V 0-3A 360W with Encoder
Adjustment
The KUAIQU SPPS-C1203 is a 0-120V 0-3A 360W DC Voltage Source and DC Power Supply designed for 120V DC System Testing, laboratory evaluation, electronic system development, and troubleshooting. Its wide adjustable voltage range allows users to establish different DC supply conditions for compatible 120V-class systems, circuits, modules, and equipment within the rated output capability.
With Encoder Adjustment, Voltage Current Power Display, CV/CC operation, and independent Output Control, the SPPS-C1203 provides a practical way to configure, apply, monitor, and repeat DC power conditions during system testing. The 120V output range also gives engineers flexibility to evaluate equipment at different DC input levels rather than being limited to a single nominal voltage.
Key Features
0-120V DC Output for 120V System Testing
The SPPS-C1203 provides a 0-120V adjustable DC output for compatible 120V DC systems and electronic equipment. Users can establish the required supply voltage within the rated range for system startup checks, operating-condition evaluation, development testing, and troubleshooting.
0-3A Current and 360W Power Capacity
With adjustable current up to 3A and maximum output power of 360W, the DC Power Supply provides controlled power for compatible DC systems and electronic loads within its rated operating range. The current setting can be adjusted according to the requirements of the equipment or circuit under test.
Encoder Adjustment for Precise Test Settings
The dual-knob Encoder Adjustment provides convenient control of voltage and current settings. It allows users to establish specific test values, make controlled changes between test conditions, and repeat selected settings during system development and verification work.
Different Resolution Above and Below 100V
For the SPPS-C1203, voltage setting and readback resolution are 10mV below 100V and 0.1V at 100V and above. This supports controlled adjustment across the full 0-120V range while allowing users to work with both lower-voltage test conditions and 100V-class system conditions.
Voltage, Current and Power Display
The 4-digit display provides real-time Voltage, Current and Power information during testing. Engineers can observe the electrical operating condition of the connected system while adjusting the DC supply and compare changes between different test settings.
CV/CC Operation for System Loads
The SPPS-C1203 supports CV/CC operation and automatically switches between constant voltage and constant current behavior according to the connected load and configured output conditions. This provides a practical operating mode for different compatible DC system loads.
Output Control for Controlled System Startup
The independent Output Control allows users to prepare voltage and current settings before applying DC power to the system under test. This is useful for controlled startup checks, power interruption tests, and repeated application or removal of DC power during system evaluation.
Adjustable Supply Conditions for System Comparison
The wide 0-120V adjustment range allows users to evaluate compatible equipment under different DC input conditions. Engineers can compare system behavior at selected voltage levels and observe corresponding changes in current and power.
Compact DC Power Supply for Test Workstations
The SPPS-C1203 combines 360W output capability with a compact bench-top design. Its temperature-controlled fan supports quieter operation during laboratory and engineering work, making it suitable for DC system testing workstations where adjustable power is required.
USB 5V/2A Output for Supporting Accessories
The integrated USB 5V/2A output can provide power for compatible USB-powered accessories used alongside the test setup, offering a convenient additional power source for supporting equipment at the workbench.
Applications
120V DC System Testing
The SPPS-C1203 provides adjustable DC power for compatible 120V-class systems and equipment, allowing engineers to establish controlled supply conditions during laboratory and engineering tests.
DC System Startup Verification
Users can preset the required voltage and current before enabling Output Control, then observe voltage, current, and power as the connected system starts operating.
120V DC Operating Condition Testing
The adjustable 0-120V output allows compatible systems to be evaluated at different DC input conditions. This can help engineers observe changes in system operation as the supply voltage is adjusted.
DC Input Voltage Comparison
Different voltage settings can be applied to compatible systems to compare operating behavior, current demand, and power consumption across multiple test conditions.
DC System Current Observation
The current display provides real-time information about the load's DC current during operation. This can help users identify changes in current demand when the system operating condition or supply voltage is changed.
DC Power Consumption Evaluation
The built-in power display allows users to observe the approximate output power being delivered during testing. This is useful when comparing power requirements between different operating conditions of compatible DC systems.
System Development and Prototype Testing
The adjustable DC Voltage Source can provide controlled power conditions for prototype systems, electronic assemblies, and DC-powered equipment during development and laboratory evaluation.
DC System Troubleshooting
The SPPS-C1203 can provide repeatable DC supply conditions while technicians investigate abnormal operating behavior, changes in current demand, or unexpected power consumption in compatible DC systems.
Repeated Power Application Testing
Output Control allows users to repeatedly apply and remove DC output during system evaluation. This supports repeated startup, shutdown, and power cycling checks for compatible equipment.
Laboratory and Engineering Verification
The 0-120V adjustable output, Encoder Adjustment, and real-time Voltage Current Power Display make the SPPS-C1203 suitable for laboratory experiments, engineering verification, prototype evaluation, and general 120V DC system testing within its rated capability.
