Adjustable DC Power Supply 120V 3A
360W SPPS1203D for Inverter Control
Testing
The KUAIQU SPPS1203D is a 360W Adjustable DC Power Supply with a 0-120V adjustable voltage range and 0-3A adjustable current range, designed for bench testing of compatible inverter control circuits, control boards, and related electronic components. For Inverter Control Testing, engineers and technicians can adjust the DC output to establish different test conditions within the rated operating range of the power supply. The full-color LCD provides four-digit voltage and current display together with power display, while the precision encoder, M1-M4 four-group memory function, output switch, and panel lock provide practical controls for repeated bench testing and verification work.
Key Features
0-120V 0-3A Adjustable DC Output
The SPPS1203D provides an adjustable DC output from 0-120V and 0-3A with a rated output power of 360W. This wide voltage range gives users flexibility when establishing different DC supply conditions for compatible inverter control circuits and electronic components.
For Inverter Control Testing, different test procedures may require different DC supply settings. The adjustable output allows users to establish the required voltage and current settings within the rated capability of the Adjustable DC Power Supply, making it suitable for development, verification, and repeated bench testing.
Precision Encoder Adjustment for Controlled Parameter Setting
The SPPS1203D uses a precision encoder for voltage and current adjustment. The encoder provides a convenient way to change the output settings when preparing different test conditions.
During Inverter Control Testing, users can adjust the DC supply according to the requirements of the test circuit and change the settings between different verification steps. This is particularly useful when several DC operating conditions need to be checked during circuit development or evaluation.
M1-M4 Four-Group Memory Function
The SPPS1203D provides an M1-M4 four-group memory function for storing commonly used settings. Repeated inverter control testing can involve recurring voltage and current parameters, and the memory function provides a convenient way to retain frequently used settings for later recall.
This can simplify test preparation when users repeatedly work with the same or similar DC supply conditions. Instead of manually entering every commonly used setting again, users can use the available memory groups as part of their recurring bench test workflow.
Full-Color LCD with Voltage, Current and Power Display
The full-color LCD provides four-digit voltage and current display along with power display, allowing users to observe the main DC output information during operation.
For Inverter Control Testing, clear visibility of voltage, current, and power values is useful when checking the actual supply condition of a compatible test circuit. The display also makes it easier to observe changes while adjusting the DC output for different test procedures.
Output Switch for Convenient Test Control
The output switch button allows users to control the DC output during bench testing. Users can prepare the required voltage and current settings and then control when the output is applied to the compatible inverter control test circuit.
This function is useful when changing test connections, preparing a new test condition, or repeating a verification procedure. It also allows the user to control the output without repeatedly changing the previously established voltage and current settings.
Panel Lock for Stable Test Settings
The panel lock button helps reduce unintended changes to the front-panel settings after the required voltage and current parameters have been established.
During repeated Inverter Control Testing, maintaining consistent test conditions can be important when comparing results from different test procedures. The panel lock provides a practical way to help keep established front-panel settings from being changed unintentionally during operation.
5V 2A USB Output
The SPPS1203D includes a 5V 2A USB output for compatible USB-powered accessories. This provides an additional fixed-voltage power option when suitable USB accessories are used together with a compatible inverter control test setup.
The USB output is separate from the main adjustable 0-120V DC output and does not replace the main Adjustable DC Power Supply output. It provides an additional 5V 2A source for compatible accessories that require this type of power input.
Applications
Inverter Control Testing
The SPPS1203D can be used as an Adjustable DC Power Supply for testing compatible inverter control circuits within its 0-120V, 0-3A, and 360W rated output capability.
Users can establish different DC supply conditions by adjusting the output voltage and current, then observe the displayed voltage, current, and power values through the full-color LCD. The output switch provides convenient control when applying or removing DC power during different stages of a test.
Inverter Control Circuit Development
During inverter control circuit development, engineers may need to evaluate circuit behavior under different DC supply conditions. The SPPS1203D provides adjustable voltage and current settings that can be changed using the precision encoder.
The M1-M4 memory function can be used for frequently repeated settings, helping users organize recurring bench test conditions during development and verification work. The panel lock can also help reduce unintended changes after a desired test setting has been established.
Inverter Control Board Verification
The SPPS1203D is suitable for providing adjustable DC power to compatible inverter control boards and related electronic control components during bench verification.
The 0-120V voltage range and 0-3A current range allow users to establish different supply conditions within the rated capability of the 360W power supply. The four-digit voltage and current display and power display provide visible output information while the test is being performed.
Repeated Inverter Test Procedures
Repeated testing may require the same or similar voltage and current settings to be established multiple times. The M1-M4 four-group memory function provides a practical way to retain commonly used settings for recurring test procedures.
The output switch can be used to control the DC output during repeated tests, while the panel lock can help reduce accidental changes to established settings. Together with the precision encoder and full-color LCD, these functions support a more organized bench testing workflow.
DC Supply Condition Verification
The SPPS1203D can provide adjustable DC power when verifying the supply conditions of compatible inverter control electronics and related circuits.
Users can adjust the output within the 0-120V and 0-3A range, observe voltage, current, and power information on the full-color LCD, and use the output switch to control the application of DC power to the test setup. These functions make the SPPS1203D suitable for laboratory and bench-level Inverter Control Testing within its rated specifications.
