The SPPS-K305 precision DC power supply is designed for sensor calibration, signal testing, embedded system debugging, and precision electronic development. With 1mV voltage setting resolution, 0.01mA current measurement resolution, and stable low-noise output, it provides accurate and reliable power for sensitive sensors, modules, and measurement circuits.
Whether you are calibrating industrial sensors, testing IoT devices, debugging embedded hardware, or verifying electronic prototypes, the SPPS-K305 helps engineers achieve repeatable test results and improve debugging efficiency.
For low-power sensors and precision circuits, small current variations can indicate important operating changes. The SPPS-K305 supports automatic A/mA range switching with 10μA readback resolution (<20mA range), allowing engineers to capture subtle current fluctuations during sensor calibration and fault analysis.
With 1mV voltage setting resolution and excellent regulation performance, the SPPS-K305 provides stable power output to reduce measurement errors caused by voltage fluctuations.
Ideal for powering:
The high-resolution 5-digit display provides clear and stable readings, helping engineers monitor real-time voltage and current changes during calibration procedures and avoid inaccurate test results.
The built-in 4 groups of memory storage allow users to save frequently used test parameters and quickly switch between different sensor test conditions, improving efficiency in production testing and laboratory development.
The SPPS-K305 integrates multiple protection functions to protect both the power supply and connected devices:
These protections help prevent damage during sensor wiring, prototype testing, and debugging operations.
Users can preset voltage and current values before enabling output, eliminating the need for temporary short-circuit adjustments and providing a safer workflow during sensor testing.
The precision encoder provides finer and smoother parameter adjustment compared with traditional knobs. The panel lock function prevents accidental changes during long-term testing or calibration processes.
Equipped with 5V/2A USB and Type-C outputs, the SPPS-K305 can directly power or charge small electronic devices, development boards, and portable test equipment.
The adjustable key sound with mute function makes the power supply suitable for both quiet laboratories and industrial workshops.
Provides stable and adjustable DC power for testing sensor output accuracy, current consumption, and operating stability.
Ideal for powering microcontrollers, development boards, communication modules, and sensor interfaces during firmware development.
Suitable for maintenance and testing of control systems, measurement equipment, and low-power industrial devices.
A compact precision power source for engineers working on prototypes, electronic circuits, and experimental setups.
