<p>The current supply unit has several load circuits and it has a safety system which comprises an overcurrent indicator (7) in each load circuit. There is a logic circuit (5) which is connected with the overcurrent indicator (7) and which is also connected with closed switch indicators, each of which is allocated to a load circuit. There is a switch (3) which is controlled by thelogic circuit in each load circuit. The logic circuit opens a corresponding switch (3) when it receives a signal that excessive current flows in this load circuit.</p> |
