QT40.241
Q-Series
24V, 40A, THREE PHASE INPUT
4. INPUT INRUSH CURRENT
The power supply is equipped with an active inrush current limitation circuit, which limits the input inrush current
after turn-on to a negligible low value. The input current is usually smaller than the steady state input current.
