Thread: ADSL Modem :Need 2 hours power backup

Hello,

I have laptop and ADSL Modem to stay connected. But, I have a regular 2 hours power failure at my work place.

Since , I use Laptop , the battery backup for the Laptop is more than 4 hours.

I need power backup for the ADSL modem so that I can stay online when there is no Power.

The typical 500VA UPS provides backup for only 10 minutes. What I need is 2 hours powerbackup.

I know there are certain ADSL modem which comes with builtin Power backup for long hours. But, I need one for my existing ADSL modem.

Please suggest!

Thanks
GIGA

WELCOME TO IBF!!!!!
connect ur modem to inverter it only consumes 9-10V so no problem.

Try suggestion above, the time UPS works may increase.
Internet connection may be lost during change over.

Mention your modem/model/make/number.
Also power output say 12 V D.C = 1 Amp etc
The modem can
be connected DIRECT to UPS 12 V
battery * conditions apply

Thanks for the reply.

My modem is 220BX beetal. Power supply spec is 5v @ 1A. what I am looking for is a STANDALONE batterybackup for this modem ONLY. Can we get something for less than Rs2000?

Thanks

@giga
1.1.Try 6V Motor cycle battery.
Direct connection from the battery
to Modem possible Observe
polarity .
1.2
Giving 6V = to beetel may not affect ,as it is
again reduced to 3 .2 V or so. inside .
1.3
to be on the safe side add in SERIES
a resistance of 1 Ohm
( to pass max 1 Amp current and drop 1 V)
1.4
SETUP
6V battery +ve ==>1 Ohm== modemplug
...................-ve =========modemplug
1.5
See para 2 item 2 about bulb instead of resistance.

Para two
2.1. An emergency light if available its battery can be also tried.
(Current rating not known modem LED's glow will
be dim I think )
2.2
A 6V torch bulb can be used in SERIES
battery +ve to bulb holder ( Insert BULB)
from bulb holder other point to modem plug +ve
Battery -ve direct to Modem plug -ve
2.3
OBSERVE POLARITY in Modem PLUG
Bulb will glow faintly or blow out !.( acts as a fuse also )
at your own risk *conditions apply !!
