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 output range provides flexibility when supplying compatible electrical equipment and electronic circuits that require different DC voltage and current conditions during testing.
For Electrical Equipment Testing, different devices and test procedures may require different DC supply settings. The Adjustable DC Power Supply allows users to adjust voltage and current within its rated operating range, making it possible to establish appropriate supply conditions for compatible equipment during development, inspection, and verification.
Precision Encoder Adjustment for Convenient Test Setup
The SPPS1203D features precision encoder adjustment for setting the output voltage and current. The encoder provides a convenient front-panel method for changing the supply parameters when preparing or modifying a test condition.
During Electrical Equipment Testing, technicians may need to change the DC supply settings between different test steps or when evaluating different compatible devices. The precision encoder makes these adjustments accessible directly from the front panel and supports a practical bench testing workflow.
M1-M4 Four-Group Memory Function
The SPPS1203D includes an M1-M4 four-group memory function for storing commonly used voltage and current settings. Electrical equipment testing can involve recurring test procedures in which the same or similar DC supply parameters need to be established multiple times.
The four memory groups provide a convenient way to retain frequently used settings for later recall. This can reduce repetitive manual adjustment when returning to established test conditions and make recurring Electrical Equipment Testing procedures more convenient.
Full-Color LCD with Four-Digit Voltage and Current Display
The full-color LCD provides four-digit voltage and current display together with power display, giving users visible information about the main DC output during operation.
For Electrical Equipment Testing, monitoring the displayed voltage, current, and power can help users observe the supply condition applied to a compatible test device. The LCD also provides direct feedback while adjusting the output or checking the operating status of the DC Test Supply during a test.
Output Switch for Controlled Test Operation
The output switch button provides direct control of the DC output. Users can prepare the required voltage and current settings before applying DC power to the compatible electrical equipment under test.
This is useful when connecting equipment, changing a test setup, or moving between different testing steps. The output switch allows users to control the application of DC power without repeatedly changing the established voltage and current settings.
Panel Lock for Maintaining Established Settings
The panel lock button helps reduce unintended changes to front-panel settings after the required voltage and current parameters have been established.
During Electrical Equipment Testing, consistent supply conditions can be useful when repeating a test or comparing results under the same settings. The panel lock provides a practical way to help maintain the established front-panel parameters during bench operation.
5V 2A USB Output for Compatible Accessories
The SPPS1203D provides a fixed 5V 2A USB output for compatible USB-powered accessories. This provides an additional power option when suitable USB accessories are used together with an electrical equipment test setup.
The USB output is separate from the main adjustable 0-120V DC output. It provides a 5V 2A source for compatible accessories while the main output can be used as the adjustable DC supply for the equipment under test within the rated specifications of the DC Test Supply.
Applications
Electrical Equipment Testing
The SPPS1203D can be used as a DC Test Supply for testing compatible electrical equipment within its 0-120V, 0-3A, and 360W rated output capability.
Users can adjust the DC voltage and current according to the requirements of the test procedure and monitor voltage, current, and power through the full-color LCD. The output switch also provides convenient control when DC power needs to be applied or removed during different stages of equipment testing.
Electrical Equipment Development
During electrical equipment development, engineers may need to evaluate compatible electronic circuits and DC-powered components under different supply conditions. The SPPS1203D provides adjustable voltage and current settings that can be changed through the precision encoder.
The M1-M4 memory function can be used to retain frequently used settings for recurring development tests. This makes it easier to return to established supply conditions when comparing different test configurations or repeating a development procedure.
Electronic Equipment Verification
The SPPS1203D can provide adjustable DC power for compatible electronic equipment, control boards, and related components during laboratory or bench verification.
Its 0-120V voltage range, 0-3A current range, and 360W rated output define the available operating range for compatible test circuits. The full-color LCD provides visible voltage, current, and power information while the output switch allows convenient control of the applied DC power.
Repeated Electrical Equipment Test Conditions
Electrical equipment verification may require the same voltage and current settings to be established repeatedly. The M1-M4 four-group memory function provides a convenient way to retain commonly used settings for recurring test procedures.
The stored settings can reduce repetitive manual adjustment when returning to familiar test conditions. Combined with precision encoder adjustment, the LCD display, output switch, and panel lock, the SPPS1203D provides practical controls for organized and repeatable bench testing.
DC Supply Condition Verification
The SPPS1203D can be used to verify DC supply conditions for compatible electrical equipment, electronic circuits, and related DC-powered components.
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 when DC power is applied to the test setup. This makes the SPPS1203D suitable for Electrical Equipment Testing within its rated specifications.
