Its standout feature is the flexibility in input sources; you can power it using the latest fast chargers based on PD and QC protocols, powerful power banks, or standard DC adapters. This capability makes the DPS-150 a truly portable power supply usable anywhere. With a 150W output power and precise voltage and current adjustment, this device is ideal for powering and testing various electronic circuits—from sensitive microcontrollers and sensors to small DC motors and LED modules. Its large color display not only shows numerical values with 4-digit accuracy but also displays voltage and current curves, which is very useful for monitoring load behavior. The presence of 8 protective layers ensures device and connected circuit safety under unexpected conditions. Strengths: Input Flexibility: Compatibility with various modern (Type-C) and traditional (DC Jack) power sources. High Accuracy and Stability: Precise voltage and current adjustment with output ripple under 20mV. Comprehensive Protection: Multiple safety mechanisms offer peace of mind against damage to the device and circuits. Excellent User Interface: Large, clear color display with curve visualization. Computer Connectivity: Ability to control and monitor through 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 Power Adapter Included: In the standard package, no input power adapter is provided; users need to procure a suitable adapter separately as per their needs. Buying Guide for the FNIRSI DPS-150 Standard Handheld Power Supply Specify Your Input Power Source: Before purchase, ensure you have a suitable power source (DC adapter, PD/QC charger) with adequate voltage and current to supply your maximum required power. Pay Attention to Buck Nature: This device cannot increase voltage. For example, to obtain 30V output, you need an input above 30V (up to 32V). Application: This device is very suitable for circuit testing, electronic repairs, student projects, and powering sensitive equipment.
