4.9 Power supply of the controller
4.9.1 Sizing of the power supply
Choose a power supply unit that is suitable for the currents in your application. The selection
depends on the maximum currents arising, as well as the type of supply (separate supply of
U
L
, U
M
, and U
S
or supply via a power supply unit).
Some electronically controlled power supplies have a fallback characteristic curve (see
Figure 4 - 8 ). They are not suitable for operation with capacitive loads.
We recommend using a primary-switched power supply (without fallback characteristic
curve) from the QUINT POWER range to operate the controller (see the latest Phoenix Con -
tact catalog).
A power supply without a fallback characteristic curve must be used for correct operation
of the controller (see Figure 4 - 9 ).
When you switch on the controller, an increased inrush current will occur briefly. The con -
troller behaves like a capacitive load when it is switched on.
