High-precision DC regulated power supplies (with output accuracy ≤0.01% and ripple ≤1mVrms) are core equipment in scenarios like precision testing and metrological calibration. However, their output accuracy gradually deviates over time (e.g., capacitor aging, resistor drift) and due to environmental changes (temperature, humidity). Long-term uncalibrated use may lead to distorted test data, such as...

As the "energy core" of electronic devices, the parameter labels of a DC regulated power supply directly determine whether it can match load requirements. However, for beginners, questions like the difference between "rated current" and "adjustable range," and the practical meaning of "0.1% voltage regulation accuracy" are often confusing. This article breaks down the...

As a core tool for electronic experiments and equipment testing, a DC regulated power supply’s lifespan depends on both hardware quality and daily maintenance. Beginners often neglect cleaning or use the device improperly, leading to premature issues like poor heat dissipation, component aging, and contact failures. This article breaks down 6 easy, effective maintenance...

With its flexible voltage and current adjustment, the adjustable DC regulated power supply has become a core tool for electronic DIY enthusiasts to power LED lights and charge batteries. However, accurately matching load parameters is crucial to ensure equipment safety and operational performance. This article takes two common scenarios—"powering LED lights" and "charging mobile...

In electronic experiments, equipment testing, or circuit maintenance, the overvoltage (OVP) and overcurrent (OCP) protection functions of DC regulated power supplies are the core safeguards for equipment safety and reliable operation. These two functions automatically respond to abnormal voltage or load faults, preventing load burnout, power supply damage, and safety accidents. This article explains...
