SPECIFICATIONS
Ac Input Inrush Current
90-264 Vac, 47-63 Hz single phase.
Inrush is limited by internal thermistor. The inrush at 230 Vac, averaged over the
first ac half-cycle under cold start conditions will not exceed 32 A.
Input Current
Maximum input current at minimum 120 Vac, 60 Hz with full rated output Temperature Coefficient
load is 0.6 A.
