The KUAIQU SPS1203S 120V 3A DC power supply provides an adjustable 0–120V output with up to 3A current for applications requiring a wider DC voltage range. Designed for industrial electronics, power modules, electronic components, control equipment, and equipment maintenance, this 120V 3A adjustable DC power supply gives engineers greater flexibility when testing circuits above the common 30V and 60V ranges.
0–120V Adjustable Output: The wide output range makes the SPS1203S a practical 120V DC power supply for electronics testing, allowing engineers to test and power electronic circuits across a broad range of operating voltages.
Extended-Voltage Testing: The 0–120V range is suitable for 120V adjustable power supply for laboratory testing, prototype development, circuit debugging, and equipment verification where a wider voltage range is required.
Industrial Electronics Testing: This 120V power supply for industrial electronics can provide controlled DC power for industrial control circuits, electronic modules, power boards, and equipment maintenance.
Power Component Evaluation: The adjustable output is useful for 120V power supply for electronic component testing, allowing engineers to apply controlled voltage and monitor circuit behavior during evaluation.
USB-A & USB-C Fast Charging: Integrated USB-A and USB-C outputs support Apple BC1.2, AFC, FCP, QC2.0/QC3.0, PD3.0, and PPS protocols for convenient charging of compatible electronic devices at the workbench.
Precise Adjustment & Protection: The encoder knob provides smooth voltage and current adjustment, while OCP and OVP protection help safeguard the power supply and connected equipment during testing.
Industrial Equipment Testing: Suitable for industrial control equipment, electronic modules, control boards, and equipment maintenance.
Power Module & Circuit Testing: Useful for testing power modules, converters, control circuits, and electronic assemblies that require an adjustable voltage source up to 120V.
Electronic Component Evaluation: Suitable for controlled testing and evaluation of components and circuits operating within the 120V output range.
R&D and Laboratory Testing: A versatile 120V bench power supply for circuit testing, prototype development, engineering verification, and laboratory applications.
