A switching power supply's output voltage being too high can be caused by several factors. Here are some common reasons and their explanations:1. Feedback Loop FaultsFaulty Feedback Resistor or Capacitor: Damage to the resistors or capacitors in the feedback loop can cause the feedback signal to be inaccurate, leading to an increase in output voltage.Optocoupler Failure: Optocouplers are commonly used in switching power supplies to transmit feedback signals. If the optocoupler is damaged or aged

Comparison and Analysis of Three-Way Switches and Four-Way SwitchesThe advantages of a three-way switch Simple Installation and Wiring: Compared to four-way switches, three-way switches have relatively simple circuit designs and installations, requiring no complex wiring, thus resulting in lower installation costs. Lower Cost: Due to the relatively simple structure of a three-way switch, its production cost and market price are typically lower than that of a four-way switch. Wide range of applic

A Ground Fault Circuit Interrupter (GFCI) socket is a protective device specifically designed to prevent an electrical shock. It can detect the leakage current in the circuit and quickly cut off the power supply when the leakage current exceeds a predetermined threshold to protect personal safety. There are many ways to determine whether the GFCI socket has electricity, and the following are some commonly used methods:Viewing lightMany GFCI outlets have an indicator light (usually red or green)

A bipolar circuit breaker is an electrical protection device used to provide overload and short circuit protection in a circuit. The main difference between it and the single-pole circuit breaker is that the bipolar circuit breaker can control two electrical routes at the same time (usually the live line and the neutral line), while the single-pole circuit breaker can only control one electrical route.Characteristics of bipolar circuit breakers Control two lines at the same time: bipolar circuit
