· Will connecting a DC switching power supply to AC power by mistake cause damage?

Whether a DC switching power supply will be damaged if AC power is mistakenly connected depends on the design and protection mechanism of the switching power supply. Modern switching power supplies are usually designed with multiple protection functions, including overvoltage protection, overcurrent protection, short circuit protection, and input voltage protection. However, these protective measures are mainly aimed at preventing issues on the output side, rather than incorrect input power supply types.Switching power supplies are typically designed to convert AC input into DC output, so their input portion is designed to handle AC power. If you are referring to mistakenly connecting a switching power supply designed for DC input (such as car power, battery, etc.) to an AC power supply, in this case:There is a dedicated AC input design: If the switching power supply has a wide input range and is clearly marked as capable of accepting AC inputs (for example, some devices can accept a...

· What is the difference between three-stage charging and five-stage charging with smart chargers?

The three-stage and five stage charging of smart chargers are both charging management technologies that adopt different control strategies during the charging process to ensure charging efficiency and battery life. The following are their main differences:90W Battery Charger1. Three Stage Charging:● Constant Current Charging Stage: During this stage, the charger provides a constant current to quickly charge the battery to its rated voltage. This stage is mainly used for fast charging batteries.● Constant Voltage Charging Stage: Once the battery voltage reaches the preset value, the charger will maintain a constant voltage while gradually reducing the charging current. This helps to prevent overcharging and maintain the safety of the battery.● Float Charging: When the battery is fully charged, the charger will maintain a lower charging voltage to maintain the battery's charging state. This can prevent overcharging and allow the battery to remain charged when needed, such as a backup b...
