Looking for a low power UPS.

[Swapnil]

I'm looking for a low power UPS that can power my TP-Link router, ISP's ONU and a 23 watt CFL bulb. 100-200VA would be more than enough for that. But all I can find are minimum 600VA. So, if anyone knows anywhere I can find a low power UPS, for cheap of course, please let me know.

u can find custom made 1 SLA battery ( 8A) based small IPS units in patuatuli/nobabpur/stadium or even local hardware store. Local ferywala and shop owner use them during power outage. Look for one that has a potentiometer to set battery charge cut off voltage or float charge( unlikely. they call it cheap charger) that u can tune later.

cost around 1300 to 1500 BDT

u total load is not more than 50 watt =12+12+23

Thanks for the info. But I probably have to first find a similar market in Chittagong. Also, I put minimum 100VA considering the power factors of the CFL, Switch mode adapters and the UPS/IPS's inverter. And I have a tendency of setting design factors to 0.5-0.75.

100va (60watt) should do the job just fine. look for street side frywala who is using similar kind of ips in your area and ask him .
