Power Supply - 24V, 5 A, 120 W, Single-phase Input Reference Manual
DC Input
The device is suitable to be supplied from a DC input voltage. Use a battery or a
similar DC source. A supply from the intermediate DC-bus of a frequency
converter is not recommended and can cause a malfunction or damage the
unit.
Connect the +pole to the L, the –pole to N, and the PE terminal to an earth wire
or to the machine ground.
Figure 5 - Wiring for DC Input
Input Inrush Current
An active inrush limitation circuit (NTCs, are bypassed by a relay contact)
limits the input inrush current after turn-on of the input voltage.
The charging current into EMI suppression capacitors is disregarded in the
first microseconds after switch-on
.
