ABSTRACT:
Disclosed are various circuits which assure safe connection of battery chargers or other electrical apparatus, wherever two sets or pairs of terminals are to be connected safely. Additionally, overload protection modules and On-time delay modules prevent overloads from being transmitted to the receiving side and delay the connection to the end terminals. Further, a minimum charger-voltage-detector version prevents use when not safe. Various embodiments of circuit modules, including using a micro processor, are presented in accordance with the invention.
