ups modem in Hindi हिन्दी

It is a very low-cost UPS for the modem. Getting a commercial 500VA UPS only for the purpose is an expensive proposition Modems / WiFi routers are often powered by an adaptor. During utility power fail internet connectivity is disrupted even if the power interruption is for less than a second. This device using a cheap Dc to Dc converter for mini battery charging can take care of small duration power interruption with zero change over time as it does not use any relays.
