hi I found that Proline 3000 also same as ba2000. but i don't know how the protection circuit works without any power supply.
pls see the attached pdf schematic. protection circuit stars only from sp out and then goes to GND.
Can any expert explain this or is there any mistake on the schematic ?
also can someone design the input board pcb layout ?
