Fonte de alimentação DC programável Fnirsi DPS150 DC Mini, modelo DPS150, saída DC ajustável com visor digital

Fnirsi DPS150 DC Mini is a compact programmable DC power supply with an adjustable DC output and a clear digital display. Designed for bench testing, prototyping and small repair tasks, the unit delivers controlled voltage and current with the ability to set limits and monitor output parameters on-screen. Its small footprint and straightforward controls make it suitable for hobby electronics, technician work and basic laboratory use.

Advantages

The device offers precise voltage and current adjustment combined with digital readout for accurate monitoring. Its programmable settings allow users to set output limits, protecting devices under test and enabling repeatable workflows. The compact design and intuitive front-panel interface reduce bench clutter and simplify routine measurements.

Suitable for

• Electronics hobbyists building or testing circuits
• Technicians performing repairs and component testing
• Small laboratories or benches requiring a compact DC source
• Prototyping and product development for low-voltage projects

When it may not be suitable

This unit is intended for low-power bench use; it may not provide the higher voltage or current ranges required for industrial equipment or high-power applications. It is also not a substitute for laboratory-grade supplies with multiple isolated outputs or extensive safety certifications when such features are required.

Key specifications

• Adjustable DC output (voltage and current control)
• Digital display for voltage and current readings
• Programmable output limits for voltage and current
• Compact form factor suitable for small workspaces

How to use

Connect the supply to a stable AC source and attach the load using appropriate leads and polarity. Use the front-panel controls to set the desired output voltage and current; enable programming or limit functions as needed to protect the device under test. Monitor the digital display while adjusting values, and switch outputs off before connecting or disconnecting sensitive circuits.

What to consider before purchase

• Required voltage and current ranges for your projects
• Need for programmable features and output limiting
• Physical size and available bench space
• Compatibility of output connectors and test leads

Recommendations

For reliable results, verify the required voltage and current for each device under test before applying power, use properly rated leads and clamps, and take advantage of the programmable limit functions to prevent overcurrent or overvoltage conditions.
