Efficiency increases as output voltage increases. Input Current Maximum input current at minimum 120 Vac, 60 Hz with full rated output Input Protection load is 0.6 A. Internal ac fuse provided on all units. Inrush Current Hold-up Time Inrush is limited by internal thermistor. The inrush at 230 Vac, averaged over the 15 ms minimum from loss of ac input at full load, nominal line (115 Vac). first ac half-cycle under cold start conditions will not exceed 32 A.
