Key Features
0–30V Adjustable DC Output
The SPS-E305 provides an adjustable DC output from 0 to 30V, allowing students and laboratory users to select an appropriate voltage for different circuit experiments, electronic projects, and low-voltage test setups.
Up to 5A Output Current
With output current adjustable up to 5A, the Laboratory DC Power Supply can provide controlled DC power for a range of classroom experiments, circuit verification tasks, and laboratory projects within its rated operating range.
150W Laboratory DC Power Supply
The 150W output rating provides practical power capacity for university laboratory experiments without requiring a larger bench power supply for basic electronics and electrical testing tasks.
Encoder Precision Adjustment
The encoder adjustment design provides a convenient way to adjust voltage and current settings during experiments. This is useful when students need to change output conditions while observing how a circuit responds.
3-Digit Display for Experiment Monitoring
The SPS-E305 uses a 3-digit display to provide a direct view of the power supply's output readings, helping students monitor operating conditions while performing laboratory experiments and circuit tests. The SPS-E305 product information identifies its three-digit display as part of the product configuration.
Compact Mini Design
Its compact form factor helps save valuable laboratory bench space. The mini Laboratory DC Power Supply can be placed alongside breadboards, electronic components, test leads, meters, and other equipment used during university experiments.
Adjustable Power for Circuit Experiments
The adjustable DC output allows one power supply to support different experiment conditions rather than requiring a separate fixed-voltage source for every laboratory exercise. This makes it suitable for teaching environments where students perform different experiments on the same workbench.
Constant Voltage and Constant Current Operation
The SPS-E305 supports constant voltage and constant current operation, allowing the power supply to respond according to the connected load and configured output conditions. This makes CV and CC operation relevant to laboratory exercises involving different circuit loads. The official product information identifies automatic constant voltage and constant current switching.
Suitable for Teaching and Research
The SPS-E305 is designed for practical DC power requirements in laboratory, research, and teaching environments. Its combination of adjustable output, encoder control, compact size, and display makes it suitable for repeated use across different university experiment setups.
Applications
University Electronics Laboratory Experiments
Use the SPS-E305 as an adjustable Laboratory DC Power Supply for undergraduate and graduate electronics experiments that require controlled DC voltage and current.
Circuit Theory Experiments
The adjustable output can support classroom experiments involving basic DC circuits, voltage changes, current behavior, and circuit response within the 30V and 5A operating range.
Electronics Teaching Labs
The compact DC Power Supply can be integrated into teaching benches where students need an adjustable power source for practical electronics exercises.
Student Circuit Projects
The SPS-E305 provides adjustable DC power for student-built circuits, prototypes, and educational electronics projects that operate within its rated output range.
Breadboard Experiment Setups
Its compact size makes it suitable for breadboard-based laboratory experiments where the power supply needs to fit alongside measurement instruments and electronic components.
Electronic Component Experiments
The adjustable DC output can be used when students need a controlled power source while studying the operating behavior of electronic components and circuits.
DC Voltage and Current Experiments
Students can adjust the voltage and current settings to create different operating conditions for laboratory demonstrations and practical circuit experiments.
Research and Prototype Work
The SPS-E305 can provide adjustable DC power for university research projects and early-stage electronic prototypes that fall within its 0–30V, 0–5A output range.
Engineering Student Training
The simple control method and direct display make the power supply suitable for practical training where students learn how to configure and monitor a laboratory DC power source.
Repeated Laboratory Testing
Its compact design and adjustable output make it practical for repeated experiment setups where students or researchers need to configure DC power for different tests throughout the laboratory session.
