POWER SPS-F305 30V 5A 150W 4-Digit DC

Bench Power Supply

The NICE-POWER SPS-F305 is a compact 4-Digit DC Bench Power Supply designed to provide adjustable DC power for embedded system development, board-level testing, prototype verification, and laboratory evaluation. With a 0-30V adjustable voltage range, 0-5A adjustable current range, and 150W maximum output power, it provides a flexible bench power source for embedded hardware operating within its rated electrical range.

Embedded system development often involves repeated testing of development boards, controller circuits, interface circuits, sensors, and other electronic hardware under different supply conditions. The SPS-F305 allows engineers and technicians to adjust voltage and current settings directly at the bench while using the 4-Digit Display to reference the selected output conditions.

Its Encoder Precision Adjustment, 10mV voltage setting resolution, and 1mA current setting resolution are particularly useful when developers need to make controlled changes during prototype testing, circuit debugging, or repeated verification. The compact Mini design also makes the SPS-F305 practical for engineering workstations where several test instruments are used together.

Key Features

0-30V Adjustable DC Output

The SPS-F305 provides an adjustable DC output from 0 to 30V, allowing engineers to establish different supply voltage conditions for compatible embedded hardware and electronic circuits.

During embedded system development, different prototypes or circuit sections may require different supply levels. The adjustable voltage range allows the same DC Bench Power Supply to be used across multiple low-voltage test setups without changing to a fixed-voltage source.

0-5A Adjustable Current Range

The adjustable current range extends from 0 to 5A, providing flexible current settings for compatible embedded boards, controller circuits, and electronic prototypes.

The available current range allows users to establish different test conditions while evaluating embedded hardware. The 5A maximum current rating should be considered together with the 150W maximum output power when selecting the operating point.

150W Maximum Output Power

With up to 150W of rated output power, the SPS-F305 can support a variety of bench-level embedded system testing applications within its specified voltage and current limits.

The 150W rating gives engineers room to work with different voltage and current combinations rather than restricting testing to a single fixed operating condition.

4-Digit Display for Test Condition Reference

The 4-Digit Display provides a clear numerical reference during embedded system testing.

For development and debugging work, engineers can observe the displayed electrical values while changing test conditions, recording experimental results, or reproducing previously established supply settings.

This is useful when the DC Bench Power Supply is being used alongside an oscilloscope, multimeter, logic analyzer, development board, or other laboratory instruments.

Encoder Precision Adjustment

The Encoder Precision Adjustment provides convenient control over voltage and current settings.

Embedded system development often requires repeated changes to the power supply during prototype testing. The encoder-based adjustment allows users to change the test conditions directly from the front panel without repeatedly changing the external power source.

10mV Voltage Setting Resolution

The voltage setting resolution is 10mV.

This allows engineers to make relatively fine adjustments when investigating how an embedded circuit or development board behaves at different supply voltage conditions. It is especially useful during bench testing where small changes in the DC supply are part of the evaluation process.

1mA Current Setting Resolution

The current setting resolution is 1mA.

Fine current adjustment can be useful when establishing repeatable test conditions for embedded hardware and comparing circuit behavior at different current settings.

The resolution specification refers to the power supply setting capability and should not be interpreted as a measurement specification for the connected embedded system.

Defined Voltage and Current Accuracy

The SPS-F305 provides specified voltage and current setting accuracy as well as readback accuracy.

These specifications give engineers quantitative information when using the DC Bench Power Supply as part of a documented embedded system test setup.

For development work that requires repeated experiments, defined accuracy specifications can also help users establish consistent test conditions.

Low-Ripple DC Output Characteristics

The SPS-F305 specifies voltage ripple of ≤60 mVp-p / ≤10 mVrms and current ripple of ≤10 mArms.

For embedded system testing, the quality of the DC supply can be an important consideration when evaluating electronic circuits and prototypes. The specified ripple values provide measurable electrical information for engineers when selecting the power source for a particular test setup.

Defined Load and Line Regulation

The SPS-F305 has specified load regulation and line regulation characteristics for voltage and current.

These specifications provide additional information about the DC Bench Power Supply's output performance under defined operating conditions and can be considered when establishing repeatable embedded system test procedures.

Fast Response for Bench Test Adjustments

The specified dynamic response is ≤200ms.

This provides a measurable reference for situations where the power supply operating condition is changed during an embedded system experiment and the connected circuit is subsequently observed.

Compact Mini Bench Design

The SPS-F305 measures approximately 18.7 × 9.8 × 8.3 cm and weighs approximately 0.7kg.

Its compact size helps conserve valuable bench space when an embedded system development workstation already includes a computer, oscilloscope, logic analyzer, multimeter, development boards, cables, and other equipment.

The small footprint also makes it convenient to move between different engineering workstations when needed.

AC100-240V Input

The SPS-F305 supports AC100-240V input, making it suitable for laboratory, workshop, engineering, and educational environments using different mains voltage conditions.

The specified input voltage and current are 110V/5A and 220V/3.15A.
