I own three little (I think they are 250 watt inverters,I haven't used
them in a long while,I have them put up somewhere around here) modern
inverters and I own a big heavy sine wave 800 watt inverter (I gave it
to my brother in law about six years ago,I bought it for $100.00 from a
company that was going out of business) and I own a small old ATR
D.C.A.C.model RMF inverter.Part of what it says on one of the metal
plates on the inverter is,Type 6 C Input 6/12 volts D.C.Output 110 Volts
Capacity 80 Watts Use 20 Amp Fuse Only ATR Manufacturing.,Inc
St.Paul,Minnesota and I own another smaller old inverter,Terado model
50127 Trav-Electric Super inverter Input 12 Volts D.C.Output 110 Volts
60 Cycle A.C.75 Watts Continuos 100 Watts Intermittent MFG By Terado
Co.,St.Paul 8 Minn.,U.S.A.
The old inverters probally aren't much worth using nowdays and I know
the ATR would need rewireing and probally some other repair work,but I
like them anyway because they are old,a piece of History.They are the
old style vibrator invertes.
