The SPS-F305 combines Encoder Precision Adjustment, a 4-Digit Display, 10mV voltage setting resolution, 1mA current setting resolution, and defined voltage and current performance specifications in a small bench-top format.

Rather than taking up the space of a larger laboratory power system, the SPS-F305 provides a practical Adjustable DC Test Supply for everyday semiconductor laboratory work, electronics development, device-level circuit evaluation, and engineering education.

Key Features

0-30V Adjustable DC Supply for Flexible Test Conditions

The 0-30V adjustable output allows users to establish different DC supply conditions without changing to another power source for each test point. Engineers can adjust the supply voltage to evaluate how a compatible semiconductor circuit behaves across multiple operating conditions within the rated range.

This makes the SPS-F305 useful when a test procedure requires several voltage points rather than a single fixed supply value.

0-5A Adjustable Current Range

The SPS-F305 provides an adjustable current range from 0 to 5A. This gives users control over the current setting when working with compatible semiconductor circuits, evaluation boards, and other low-voltage electronic test setups.

The 5A rating should be considered together with the 150W maximum output power when determining the appropriate voltage and current combination for a particular test.

150W Output for Bench-Level Semiconductor Work

With a maximum output power of 150W, the SPS-F305 is suited to a broad range of low-voltage laboratory and bench testing tasks.

For example, a test may operate at a higher voltage with a lower current or at a lower voltage with a higher current, provided the operating point remains within the power supply's rated output capability.

This makes the 150W specification more useful for engineers than simply treating voltage and current as independent maximum values.

4-Digit Display for Clear Test Reference

The 4-Digit Display provides a clear numerical reference while setting and monitoring the power supply output.

For semiconductor-related testing, this is useful when an engineer needs to document test conditions, reproduce an earlier experiment, or compare circuit behavior at several supply settings.

A clear digital readout can also make bench work more convenient when the power supply is positioned alongside oscilloscopes, multimeters, electronic loads, development boards, and other laboratory equipment.

Encoder Precision Adjustment for Repeatable Setup

The Encoder Precision Adjustment provides a practical way to change voltage and current settings during laboratory testing.

For semiconductor circuit evaluation, users may need to move through multiple supply conditions during characterization or troubleshooting. An encoder-based adjustment method makes repeated changes more controlled and convenient than constantly changing external connections or using separate fixed-voltage sources.

10mV Voltage Setting Resolution

The 10mV voltage setting resolution allows users to establish fine voltage changes within the 0-30V output range.

This can be useful when an engineer is comparing circuit behavior around different DC supply levels or needs to reproduce a previously recorded test condition with greater precision.

The resolution specification should be understood as the setting resolution of the power supply, rather than a claim about semiconductor measurement accuracy.

1mA Current Setting Resolution

The current setting resolution is 1mA within the 0-5A adjustable current range.

This provides fine control when establishing different current settings for compatible semiconductor circuits and electronic test setups. It can also make repeated test procedures easier to reproduce when a defined current setting is part of the experimental procedure.

Defined Voltage Setting and Readback Accuracy

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

For laboratory users, these specifications provide quantitative information for evaluating the power supply as part of a test setup. They can also be recorded alongside other test parameters when documenting semiconductor-related experiments.

Defined Current Setting and Readback Accuracy

Current setting and readback accuracy are also specified for the SPS-F305.

This gives engineers measurable electrical specifications to consider when establishing and recording current conditions during compatible semiconductor circuit testing.

Low-Ripple Output Characteristics

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

For semiconductor-related bench testing, ripple can be one of the electrical characteristics engineers consider when selecting a DC test source. The specified ripple values provide concrete performance information rather than relying on general claims such as "clean power" or "ultra-low noise."

Defined Load Regulation and Line Regulation

The SPS-F305 provides specified load regulation and line regulation values for both voltage and current.

These specifications describe measurable output characteristics and give engineers additional information when evaluating how the DC Power Supply performs as part of a laboratory test setup.

Defined Dynamic Response

The specified dynamic response is ≤200ms.

This provides a measurable reference for test setups where the power supply operating condition is changed and the response of the connected circuit is subsequently observed.

Compact Mini Bench Format

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

The compact form factor is useful for engineering benches where multiple instruments may already be occupying the available workspace. It can be positioned alongside test instruments without requiring the footprint of a larger laboratory power supply.

AC100-240V Input

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

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

Applications

Semiconductor Device Bench Testing

The SPS-F305 can be used as an Adjustable DC Test Supply for compatible semiconductor device test setups that operate within its 0-30V, 0-5A, and 150W rated output range.

The adjustable voltage and current settings allow users to compare circuit behavior at multiple operating points.

For example, an engineer can establish one supply condition, record the circuit response, then change the supply setting and repeat the observation using the same test setup.

Low-Voltage Semiconductor Circuit Development

The 0-30V output range makes the SPS-F305 suitable for compatible low-voltage semiconductor circuits under development.

It can serve as a general-purpose DC source during early-stage circuit development before a dedicated test system or production test fixture is introduced.

Semiconductor Test Circuit Development

The SPS-F305 can be used while developing test circuits that require an adjustable DC source.

The 4-Digit Display and Encoder Precision Adjustment allow the engineer to change and reference test conditions while developing the surrounding circuit.

Supply Voltage Variation Testing

The adjustable 0-30V output allows users to establish multiple supply voltage conditions when evaluating compatible semiconductor circuits.

This can help engineers observe whether circuit behavior changes as the supply voltage is adjusted within the intended operating range.

Current Condition Evaluation

The 0-5A adjustable current range and 1mA current setting resolution allow users to establish different current settings for compatible semiconductor-related test circuits.

This provides a controllable bench source for experiments where current is one of the variables being evaluated.
