Frequent power outages, long power outages, and irregular power outages at base stations result in frequent charging and discharging of batteries, which is the main reason for the rapid decrease in battery capacity and shortened service life.The setting parameters of the switch power supply are unre Read More

We often encounter a core issue in project design: must the main circuit (rectifier) input and bypass (static bypass) input of UPS come from the same power source (i.e. "same source")? This may seem like a simple wiring issue, but it actually involves multiple aspects such as the working principle, Read More

In the fields of communication, data centers, and building power distribution, UPS (uninterruptible power supply) and EPS (emergency power supply) are two crucial types of power supply equipment. They may appear to have similar functions, but in reality, their design concepts, technical principles, Read More

Statement 1: STS adopts the "first break, then close" technology to achieve short-term switching Statement 2: STS adopts the "close before break" technology to achieve uninterrupted switching Statement 3: Why does the STS switching time still take 4-8 milliseconds if it is a "close first, then disc Read More
