its a sticking point with them better u wear safety glasses if you spell it the other way

Hey steve-o!

i picked up a phase angle speed controller today..............wanna give it a go on that monster pump of yours some time over the weekend??

... so that's J O'k then Jaymie???

Steve ... what's a "a phase angle speed controller" and what exactly does it do... advantages??

U busted me rupe! i just wanted to sound all intelligent and shit It was a pre-fab'ed module from jaycar, mean as a dimmer for resistive and inductive loads (sorry for the jargon). Can be used well on universal motors (drills hair dryers and basically anything GMC

NOT really meant for start capacitor motors, but instructions said that it MAY work. Most of the motorrs i deal with a permanent split pahse (240V) with a run capacitor, and almost evey ducted heater has a spped control on the control board for this motor.

Steve-o's motor is of the same type so i'll give it a go and report back.

i'm fairly sure it just chops the sine wave to give reduced power. Versus other means................

Chop the sine wave at the peak and i guess you have 50% RMS voltage.

Straight reduction in voltage DEFINATLY won't work with most AC motors i think even a 20% voltage drop causes them to over heat.

Steve

yep, in a past life there are a few of us here too

Leave it for the expert(s) mate.... ya just don't cut it

Yeah, you've got to get the spelling right! Double "ff" if you don't mind. Jaymie, I am Ange and Reetz's sister.

rupe:

gosh Julie, how many of there are you?

Starting to look like an invasion

Cool system by the way, real good use of space

Ask steve-o

Julie, your mans name isn't Steve as well is it?? LOL

Oh, i forgot....................i did some testing is s&a's tank

Their perch will happily eat;

serlion steak
silverbeet
chocolate cake

They tried the poached eggwhite but didn't like it. Harry and Victor (two two convict chiclids in there) did like the poached eggwhites though.

Good idea Steve.... do your trails and tests in someone elses system LOL

That's what I call "taking one for the team" LOL
