switch-off characteristic
of the excess currentswitch-off characteristic selectable: Ia = 1.0 ... 1.25 x set value, shutdown after typ. 10 s; Ia = 1.0 ... 1.5 x set value, shutdown after typ. 5 s; Ia = 1.0 ... 1.7 x set value, shutdown after typ. 1 s
of the current limitationIa = 1.8 x set value, switch-off after typ. 10-100 ms
of the immediate switch-offIout > set value and Vin < 20 V, switch-off after approx. 0.5 ms
