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. 0.03%/°C typical on all outputs. Hold-up Time Environmental 15 ms minimum from loss of ac input at full load, nominal line (120 Vac). Designed for 0 to 50°C operation at full rated output power; derate output current and total output power by 2.5% per °C between 50 - 70°C.
