Due to cost, market, volume, weight and other reasons, UPS power supply design has many forms, each of which has different characteristics. Some use working frequency, some use high frequency, some are online, and some are standby. When these forms are combined with strength and delay, they become colorful. Some of these UPS power supplies have switching gaps of 5 milliseconds and 10 milliseconds. Others have no transition gap, that is, the transition gap is 0 milliseconds.

When purchasing UPS, you should understand the performance characteristics of various models and choose the UPS that suits you according to the requirements of your own application. Different design structures have different costs. Just to solve the problem of lighting UPS, we can ignore the switch gap, and even turn on the power supply after the power failure in lighting occasions with low requirements. This form of cost is relatively low.

But for some important places, UPS power supply is not allowed to have gaps, so I still have to buy online. The simple description is that the DC rectified by the mains voltage is connected to the inverter at the same time with the battery, and the rectified voltage is slightly higher than the battery voltage, and the battery remains in a floating state (single section 13.8V). At this time, if the commercial power is interrupted, the battery will take over the rectification power supply without gap, and the UPS output terminal will hardly feel the change.

If you want to switch the UPS power supply to 0 gap, buy this UPS power supply.
