KUAIQU SPS-C1203 Power Electronics
Test Supply 0-120V 0-3A 360W with
Voltage and Current Display
The KUAIQU SPS-C1203 is a 0-120V, 0-3A, 360W Power Electronics Test Supply developed for laboratory evaluation of power circuits, DC-powered prototypes, conversion-related circuits, and other compatible electronic systems. Its wide voltage range gives test engineers more room to establish different DC operating points, while the adjustable current setting allows the supply condition to be changed as a test progresses. Voltage, current, and power readings are available directly on the unit, making the SPS-C1203 suitable for hands-on comparison of different test conditions.
In power electronics development, a circuit may need to be checked at several supply levels rather than under one fixed condition. The SPS-C1203 can be used to establish an initial DC test condition, adjust the voltage or current setting, observe the resulting readings, and repeat the procedure at another operating point. This approach is useful for prototype evaluation and laboratory testing where the relationship between the supply condition and the circuit's electrical behavior needs to be observed.
Key Features
0-120V Range for Multiple DC Test Points
The SPS-C1203 provides an adjustable 0-120V DC output with up to 3A and 360W of output power. The wide voltage range allows one Power Electronics Test Supply to cover multiple DC test points instead of limiting the test setup to a single supply level.
Adjustable Current for Changing Test Conditions
The current setting can be adjusted within the 0-3A output range to establish different supply conditions during bench testing. This gives the operator a practical way to change the electrical test setup when evaluating compatible power circuits or prototypes.
Voltage, Current, and Power Readings at the Bench
The SPS-C1203 provides Voltage and Current Display together with Power Display. These readings allow the operator to see the supply condition while making adjustments, providing useful reference values when comparing one test point with another.
CV/CC Operation for Different Evaluation Methods
The SPS-C1203 supports Constant Voltage (CV) and Constant Current (CC) operation. The two operating modes give users flexibility when setting up different laboratory test procedures without requiring a separate type of DC source for each basic test condition.
4-Knob Adjustment for Hands-On Test Changes
The 4-Knob Adjustment is designed for direct operation from the front panel. During a test, the operator can make changes to the voltage and current settings and immediately observe the displayed electrical values, which is useful when working through a series of test points.
Output Switch for Separating Test Stages
The Output Switch provides direct control over the DC output. It can be used when moving from one stage of a bench test to another, such as preparing the circuit, changing the supply setting, and starting the next measurement.
5V/2A USB Output for General Bench Use
The integrated 5V/2A USB Output provides power for compatible USB accessories used at the test bench. It adds an auxiliary power option for general laboratory use alongside the main adjustable DC output.
Applications
Power Electronics Prototype Evaluation
During prototype development, the required DC supply condition may change as the circuit is evaluated. The SPS-C1203 allows the operator to adjust the supply and observe voltage, current, and power readings at different test points.
DC Input Condition Comparison
The SPS-C1203 can be used to provide different DC input conditions to compatible power circuits. Test engineers can change the supply setting and compare the displayed electrical values between different operating points during laboratory evaluation.
Power Conversion Circuit Bench Testing
For compatible power conversion circuits, the SPS-C1203 can serve as the adjustable DC source used to establish the test input condition. Its 0-120V range provides flexibility when the circuit needs to be evaluated at more than one voltage level.
Electrical Operating Point Evaluation
Rather than testing a circuit at only one setting, users can establish a series of DC operating points within the power supply's ratings. The Voltage and Current Display and Power Display provide direct readings that can be referenced when moving between test conditions.
Power Circuit Development and Verification
The SPS-C1203 can support bench work during the development and verification of compatible power circuits. The operator can change voltage and current settings, observe the response of the test setup, and repeat the evaluation at another selected condition.
Higher-Voltage DC Test Applications
With output adjustment up to 120V, the SPS-C1203 can support compatible power electronics applications that require higher DC test voltages than typical low-voltage bench supplies. The available 0-3A current and 360W power ratings define the operating range for these applications.
Repeated Laboratory Testing
For repeated tests, the operator can establish a test condition, control the output, record the displayed voltage, current, and power values, then move to another condition. The direct controls make this workflow practical for laboratory and engineering bench testing.

Why Choose KUAIQU SPS-C1203?
The KUAIQU SPS-C1203 combines a wide 0-120V adjustable output, 0-3A current capability, and 360W output power in a Laboratory DC Power Supply intended for flexible power electronics bench work. Its 120V maximum output gives engineers more room to move between different DC test points, while the adjustable current setting provides additional control over the supply condition.
For laboratory evaluation, the SPS-C1203 can be used as part of a repeatable test workflow: establish a DC condition, enable the output, observe the voltage and current readings, check the displayed power, adjust the test point, and repeat the evaluation. The 4-Knob Adjustment and CV/CC operation provide direct control without introducing functions that are outside the product's actual design.
The SPS-C1203 is a general-purpose Power Electronics Test Supply, not a dedicated programmable power analyzer or semiconductor characterization instrument. Its practical advantage is the combination of a wide 0-120V range, 0-3A output, 360W capacity, direct front-panel adjustment, and voltage, current, and power displays for compatible laboratory testing.
