servomate Heavy Duty Mainline Automatic Voltage Stabilizer (Blue, 5KVA, 90v-300v)

Can it be used to connect to ups (2.2kva) and then ups to desktop?

Will it work for 1.5 ton ac.If I install it at main point. Then will give full voltage to my dedicated stabelizer(only work from 170v) for inverter ac

Can i use this for my durfit tread mill. is this a servo stabilizer

The input is 240v and i get output of 216v, it is less for 230v appliances. will it damage my appliances because output is only 216v??
