Use a power supply unit suitable for the currents in your application. The selection depends
on the bus configuration, the resulting maximum currents and the type of supply (separate

A power supply without a fall-back characteristic curve must be used for correct
operation of the Inline Controller (see Figure 2-22).
When the Inline Controller is switched on, an increased inrush current is temporarily
triggered. The Inline Controller behaves like a capacitive load when it is switched on.
Some electronically controlled power supplies have a fall-back characteristic curve (see
Figure 2-21). They are not suitable for operation with capacitive loads.
A primary switched-mode power supply unit (without fall-back characteristic curve) from
the QUINT POWER range (see INTERFACE catalog from Phoenix Contact) is
recommended for Inline Controller operation.
