Hi Tom, Looking around the inverters have come a long way since I had an old Lafayette inverter. On the site http://www.topsalesdepot.com/poinwinchfu.html they have inverters that have an output 2200, 3,000 and 5,000 output. They give a fantastic description of the units except that don't state how long a 12v deep cycle battery would last. The old inverter that I had had a 300W output and would kill a battery in about 4 hours just powering a 75W light bulb. I have no idea what the efficiency rating was but probably not very good. On the input side it had a 30A fuse and it had one very large transformer. I originally pade close to $200 for that unit. That was in the early 1970s. Years later I sold it at a yard sale for about $20. ----- Original Message ----- From: "Tom Fowle" <[EMAIL PROTECTED]> To: <[email protected]> Cc: <[EMAIL PROTECTED]> Sent: Sunday, November 11, 2007 11:35 AM Subject: Re: [BlindHandyMan] battery aC
spiro, they're called inverters for weird historical reasons. They turn 12 volts D.C. into 120 volts A.C. Some come as complete packages with battery and charger built in. You have to consider the actual power required by your intended load device, if it's electronics will probably wor fine. Some less expensive inverters don't produce clean enough A.C. wave forms to work well with devices that contain transformers, as often you get what you pay for. You don't want to use inverters with anything that needs lots of power I.E. heaters or appliances that produce heat etc. or heavy power tools. tom Net-Tamer V 1.13 Beta - Registered To listen to the show archives go to link http://acbradio.org/handyman.html or ftp://ftp.acbradio.org/acbradio-archives/handyman/ The Pod Cast address for the Blind Handy Man Show is. http://www.acbradio.org/news/xml/podcast.php?pgm=saturday Visit The Blind Handy Man Files Page To Review Contributions From Various List Members At The Following address: http://www.jaws-users.com/handyman/ Visit the archives page at the following address http://www.mail-archive.com/[email protected]/ If you would like to join the Blind Computing list, then visit the following address for more information: http://jaws-users.com/mailman/listinfo/blind-computing_jaws-users.com For a complete list of email commands pertaining to the Blind Handy Man list just send a blank message to: [EMAIL PROTECTED] Yahoo!
