Hi Guy's,
I have a very old machine and wondering if anyone has upgraded the control for short duration impulse heater bars? The tranny is a 3phase 415VAC - 42VAC 4kW and currently it is a single SCR by the looks of it to give only half wave.
Operating voltage is around 20-30V @ up to 60-80A.
Wondering if changing to an SSR and control via a AB L3 plc would be the way to go as there are a lot of old cards that are no longer available that control the existing. I might even look at the new wire compounds as I am sure that these days the 400mm long wire would not need 4kW to seal meat bags.
