Device for feeding variable loads

摘要

A circuit (E) for supplying variable loads comprises a first condition having two connections to at least one current source and three connections to a second source. Connection (8) is made to two loads (R2,R3), third and fifth connections are to a reference potential and the circuit can be switched to a condition in which fourth and eighth connections are joined. An independent claim is also included for an arrangement to supply current to variable loads as above.
