## What is Suvastika PSW ATC?

Smart UPS with ATC 
This UPS app operates on BLE only, and it has been designed in India specially for the users who use inverter UPS and Home UPS for the home and offices for the power backup functions. This is a specially designed app where the UPS, when operated, can show all the features on the app as the protocol written in the UPS sends the commands to the BLE chip and BLE through the app, offers all those features. This is a two-way app where the UPS with ATC gets the base from the app and can change the settings without touching any UPS button.
This app shows to the customer the voltage and frequency coming to his place through visual and readable parameters. So in case of voltage goes beyond a settable limit, then it switches the connected load to the battery mode, which is shown as UPS mode, and it keeps giving an alert message of low voltage or high voltage to the user. On the Mains mode, only in case of overload through the UPS wiring, the MCB trips, and the alert is shown to the user as it has the double protection for the home and offices. 
In case of a power cut, it shows that it's working on battery mode, as it will give the tone of the message. Also, in case of overload on the battery mode, it provides an alert with style, and in case of a short circuit, it shows the sign and gives directions to the user what in case of any warning on what to do. In this UPS, the best feature is that one can select the type of battery and size of the battery as the user can install a tubular smf or Lithium battery at his site and can make the settings through the app. Another essential feature is that there is an ATC feature which is Automatic Temperature Compensation which is very important for Tubular Lead acid battery which shows how the temperature change changes the boost voltage, which keeps the battery life and water intact and also saves the power in charging as well improve the backup time in winters. Another critical feature is Input output connections done wrongly by the user also get an alert in the app. This app is full of features, and we will keep updating the app from time to time with the feedback of the users
