1 In AC powered mode: LM types: 47...440 Hz; LMZ types: 47...65 Hz. See: AC-DC Converters
≤100 W: M-Series.
2 With multiple output modules, the same condition for each output applies.
3 RS = source resistance.
4 Value for initial switch-on cycle.
5 1 s max., duty cycle 1% max.
6 Iinr p = Ui/(Rs + Ri). See also: Inrush Current.
