Anyone had any issues running modified sine wave inverters? I know that I have to modify Fluro fittings (Removal of the PF Correction Cap) for them to be happy but has anyone else had issues with running equipment off an inverter? Looking at a 1000Watt modified sine wave unit. $280 New.

(1000 Continuous 2000peak) As you realise some things wont like the square wave.. personally I just use a modified unit with a kinda lumpy curve which behaves much better . : > Anyone had any issues running modified sine wave inverters? : > [quoted text clipped - 5 lines] : As you realise some things wont like the square wave.. personally I just : use a modified unit with a kinda lumpy curve which behaves much better . I was trying to think of a way to filter the wave a bit better (smoother) with caps etc but its been a LOONG time since I did that sort of stuff at Tafe. > : > Anyone had any issues running modified sine wave inverters? > : > [quoted text clipped - 9 lines] > I was trying to think of a way to filter the wave a bit better (smoother) with caps etc but its been > a LOONG time since I did that sort of stuff at Tafe. shove it into a cheap ups.. > I was trying to think of a way to filter the wave a bit better > (smoother) with caps etc but its been a LOONG time since I did that sort > of stuff at Tafe. buy a better quality inverter. > Anyone had any issues running modified sine wave inverters? Equipment and inverter are? It really depends on the combo. : > Anyone had any issues running modified sine wave inverters? : : Equipment and inverter are? : It really depends on the combo. Its a Projecta brand, made in China of course. Low Bat alarm, thermal OL. Im going to run a Laptop, battery chargers, a printer and some power tools from it. I think it will be fine but Im wondering about the variable speed drills etc and any equipment that I shouldnt use on it. Im sure for $280 it will be fine for basic use but I was wondering if anyone had issues whenusing inverters. Im not going to spend $1000 on a pure sine wave unit as I dont think that I will have the need (Yet). > : > Anyone had any issues running modified sine wave inverters? > : [quoted text clipped - 12 lines] > Im not going to spend $1000 on a pure sine wave unit as I dont think that I will have the need > (Yet). I expect you can buy a dc/dc supply for the lappy , variable stuff can be substituted by battery tools as the charger should be fine being switch mode .. not sure about the printer but once again depending a dc/dc might be in order . : > : > Anyone had any issues running modified sine wave inverters? : > : [quoted text clipped - 17 lines] : switch mode .. not sure about the printer but once again depending a : dc/dc might be in order . As both the laptop and Printer use Power pack converters Im 80% certain that they will be okay filtering out the ripples themselves with the caps and filters in place. > : > : > Anyone had any issues running modified sine wave inverters? > : > : [quoted text clipped - 22 lines] > As both the laptop and Printer use Power pack converters Im 80% certain that they will be okay > filtering out the ripples themselves with the caps and filters in place. My Toshi lappy wont run well on a square wave , a 100$ ups from msy sorted it : > : > : > Anyone had any issues running modified sine wave inverters? : > : > : [quoted text clipped - 25 lines] : My Toshi lappy wont run well on a square wave , a 100$ ups from msy : sorted it Whats the UPS output and input voltages anc current capabilities though?? > : > "atec 7 7" <"atec 77 "@hotmail.com> wrote in message > news:h0ulqp$u5p$1@news.eternal-september.org...

Happy with it and picked it up for $250. 1000Watt continuous and 2000 Peak so I can run a 900 watt drill no worries. > : > "atec 7 7" <"atec 77 "@hotmail.com> wrote in message > news:h0uom9$p0g$1@news.eternal-september.org...

I have done the same thing but found a small Honda genny a better deal , 1200 watts is damned cheap for what they are.. If I blow the big Hitachi drill thats quite a lot of money . > Nah, not enough.

Be quick off the trigger if you stall the drill and do not try to start it under load. > Jun 2009 19:36:34 +1000, Scotty wrote: : > : > Anyone had any issues running modified sine wave inverters? : [quoted text clipped - 5 lines] > > Im going to run a Laptop, If the inverter or the lappie power suppliers get hot, then stop using it. Experiene says there is a mistmatch. IMO, all lappies really only need a 12V supply, but the extra voltage is for internal ectivifcation and controls. > battery chargers, Long term, look for something that runs directly off your battery. Why waste power jacking the voltage up, then regulating it back down. > a printer > and some power tools from it. > I think it will be fine but Im wondering about the > variable speed drills etc and any equipment that I shouldnt use on it. The devil is in the controll circuitry of the tool. The problem with some inverters is that the zero crossing is slimmer than the control circuitry expects and the control circuitry ends up switching bigger currents than it is designed for. > Im sure for $280 it will be fine for basic use but I was wondering if > anyone had issues whenusing inverters. I probably have two of the same ilk. I've blow a 50W version running a lappie that required 60watts, but that is currently my only bad experience. > Im not going to spend $1000 on a pure sine wave unit as I dont think > that I will have the need (Yet). Frankly, a genny would be the way to go, unless noise is the factor.  SignatureOnce again, our prime minister Kevin Rudd brings stability to the nation by reassurring the nation that one law still exists for the rich and another for the poor.

Space and expense are the main factors, mainly space. Also we are not supposed to carry more than 2litres of flammible goods, with CRC, Conduit Glue, Butane etc etc a gennie would take me well over the allowable mark. The fumes and noise are the other down sides for me. Ill see how it goes and if theres a drama Ill let ya know ;o) |
