Yeah, but the whole idea is to have every device with dual inputs.... Gino A. Villarini [EMAIL PROTECTED] Aeronet Wireless Broadband Corp. tel 787.273.4143 fax 787.273.4145

Just a quick follow up. A quick search of the internet shows up a lot of devices. (APC makes a few different types). These are either called Dual AC Automatic Transfer Switch. Or depending on your voltage needs, you could modify an Dual AC power supply module for Computer Or find a AC to DC rack mount powersupplies used in Telco's . They are typically modular but big and heavy. Many options.

Depending on how your sites are designed, APC makes a Dual Feed AC swtich for this purpose.

We have a reason for this, we design our sites with dual power work ease of work ...Side A and Side B. Side A is connected to the UPS Plant, Side B to Utility. In Case Of UPS failure, we are not out.

Yes, you could do this.... You will need to pick the right diode for the job. But what brings this on? I've had almost no PS failures that were not part of some major damage. (lightning, power co. problem... 480V on 110V line) If you are having many PS failures, you might look at the load vs the PS rating. Don't forget the radio cards... CHUCK PROFITO wrote: OK guys, don't LOL, I'm just a farm boy, but... Why couldn't you put two power supplies together into one plug, then if one failed the other would do full duty. Would a diode inline on both stop a possible transformer shorting the other out or draining the power from the good one? Can that work?
