Professional Review of the Programmable FNIRSI DPS-150 Standard Power Supply
The FNIRSI DPS-150 power supply is a DC-to-DC step-down (Buck) module designed with modern features to meet the needs of electronics professionals, repair technicians, and enthusiasts. Its standout feature is flexibility in input source; it can be powered by the latest PD and QC fast chargers, robust power banks, or standard DC adapters. This makes the DPS-150 a truly portable power supply usable anywhere.
With 150 watts output power and precise voltage and current adjustment capabilities, it is ideal for powering and testing various electronic circuits, from microcontrollers and sensitive sensors to small DC motors and LED modules. Its large color display not only shows numerical values with 4-digit precision but also plots voltage and current graphs, useful for load behavior monitoring. The presence of 8 layers of protection ensures device and circuit safety under unexpected conditions.
Strengths:
Input flexibility: Compatible with modern (Type-C) and traditional (DC Jack) power sources.
High accuracy and stability: Precise voltage and current setting with output ripple less than 20mV.
Complete protection: Multiple safety mechanisms provide peace of mind against device and circuit damage.
Excellent user interface: Large, clear color display with curve visualization.
Computer connectivity: Control and monitoring possible via desktop software.
Limitations:
Step-down operation: This device is a Buck converter, meaning the input voltage must always be higher than the desired output voltage.
No included adapter: The standard package lacks an input power adapter; users must obtain it separately as needed.
Buying Guide for the FNIRSI DPS-150 Handheld Power Supply Standard
Specify your input power source: Before purchase, ensure you have an appropriate power source (DC adapter, PD/QC charger) with sufficient voltage and current to supply your maximum power requirements.
Note step-down nature: The device cannot increase voltage. For example, to output 30 volts, you need an input voltage above 30 volts (up to 32 volts).
Usage: Ideal for circuit testing, electronic repairs, student projects, and powering sensitive equipment.
