CPS20.241, CPS20.241-A1
C-Series
24V, 20A, SINGLE PHASE INPUT
4. DC-INPUT
Do not operate this power supply with DC-input voltage. Use the CPS20.241-D1 unit instead.
5. INPUT INRUSH CURRENT
An active inrush limitation circuit limits the input inrush current after turn-on of the input voltage and after short
input voltage interruptions.
The charging current into EMI suppression capacitors is disregarded in the first microseconds after switch-on.
