SSR´s and PTS motorcontroler

[Jens.J]

Does anybody know if the PTS motorcontroler can control more than one SSR?
The reason i´m asking is that i live i Sweden and our powesystem is a little bit difrent than US,
We have 3phase 230volts whith neutral and i only have 20amps main fuse.
I´m planning to build a 8 motor bench using this layout: Phase1 3motors, Phase2 3motors and phase3 2motors
so i either need 3 SSR´s or if thisone that i found at HBC controls work [urlhttp://www.hbcontrols.com/userfiles/3%20Phase%20K%20series.pdf][/url]
Going up in mainfuse size to 25amp would cost 300 to 350 usd a year so that i not an option.


Thanks Jens J

Jens, welcome to the Forum.
The PTS motor controller outputs a dc control voltage which can easily control multiple SSRs.

Each SSR will requires it's own control circuit board and it's own small 24 volt transformer to synchronize to the phase to which each SSR is connected.

Just treat each SSR as a separate independent single phase controller, connected between each 230v phase and neutral, and parallel all the dc input control voltages together into the PTS pressure controller output.

Ok that is perfekt! Now i have the electrical side under control so it´s time to order some parts
Thanks
