2 Functional description
This unit works as a constant voltage source or a constant current source depending on the load. The
output voltage is constant until the nominal current is reached. If more current is needed by the load
the device reduces the output voltage to ensure the nominal current is not exceeded. The U/I
behavior of the output is shown on Figure 2, nominal voltage (Unom) and nominal current (Inom) are
user settable and, depending on the operating mode (explained below), can be altered by the
ENABLE input.
