Hi friends,

I need a lead acid battery charger to charge a 200ah battery, the charger should be non-switch mode type, and the charger transformer is controlled by the primary side.

What you mean by and the charger transformer is controlled by the pimary side ?

Aslo we know it is 200AH but what voltage how quick to you want to charge the batteries 12hr/14hr ,

Hi max,
 
         I think you can do that by using SCR circuit controlled a primary or secondary side of transformer, but you said "the charger should be non-switch mode type" (SCR is a switch too). If the circuit is out of swithed mode component, how you can controlled the system eg current and voltage that charging your lead-acid battery. Or you can controlled it by hand?

please tell me more,
thanks

There are old chargers that use transformers with multiple taps in the secundary side, then you can select the most appropriate voltage for the moment. Another way is transformers with mobile core, but it is very difficult to find. Some electric welder use it.
