| power supply 327w what??
hi - ineed a new power supply for westell 327w
i checkecked the modem is fine, the power supply is crappiy.
now,
the back of westell supply is:
Input: AC 100-240V 50/60Hz 21W
Output: DC 12V 1000mA
--------------
i found at a discount store a discount item;
Input: AC 100-240V 50/60Hz 50W
Output: DC 12V 1000mA
can i get that one - i am worried it will fry something??
thx!!

Clemson, SC | Their output is identical.
It should work as long as the +/- polarity on the barrel connector is the same (and it fits).
The difference between 21W input and 50W in just means the discount store item is much less efficient. |

I would spend a little extra and look for a 'brick' that has a switching power supply vs a old technology transformer that is heavy, runs hotter, less effecient, falls out of the outlet and usually burns out.
At least get a regulated 'brick', not just a xformer w/ a diode in a plastic cube.

I've had a westell 327w for 3 years.The first year it worked fine, no slowdowns. always had a constant speed.The 2nd year it got very erratic, speed went way down. I noticed it was getting hot. (I have a degree in electronics). My specialty was finding ways to cool circuits. I got the original schematic for it. IT WAS DESIGNED FOR A 9 VOLT INPUT **NOT 12 VOLTS**. I put a variable power supply on it, started at
6 volts, tuned it of & on at different voltages. The best voltage WAS 9 volts, 500Mma.If you don't believe me, DO THIS. Take a volt meter (strip the wires on the power supply just enough to touch the meter leads to it & put your 12volt adapter on it, plug it in, measure the voltage. It & will read 9.5 volts. It has a cheep regulator circuit inside, to keep the voltage at 9 volts.Using a 12 volt adapter makes the regulator circuit hot, the heat spreads inside to other critical parts, then all the circuits go out of phase.I CAUGHT IT JUST IN TIME. Bean steady now for almost 2 years.
DO NOT USE A REGULATED POWER SUPPLY. A 12volt regulated power supply tries to keep the voltage at a steady 12 volts which will burn out the modem. Use an 9volt 500 - 1000 ma power supply. |
