Has anybody come across one of these in their travels? It appears to be controlling a 18Kw Quartz(halogen)IR heater bank, by full wave semi controlled SCR bridge rectifier giving 0-240Vdc to the heating elements conrolled by 0-20mA input from a PLC.
I can't find any manufacturers name or part no. except the MAP133, extensive goole searches have not been able to locate such a beastie.
Just to add the machine this is on was manufactured circa 1984.
I'm hoping someone recognises it.
