Inrush Current 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 load is 0.6 A. Temperature Coefficient 0.03%/°C typical on all outputs. Hold-up Time 15 ms minimum from loss of ac input at full load, nominal line (120 Vac). Environmental 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. See Environmental and Packaging Specifications on next page. Output Power Normal continuous output power is 25 W, 28 W peak for 60 sec. maximum duration, 10% duty cycle. Factory set to begin power limiting at approximately 30 W. EMI/EMC Compliance All models include built-in EMI filtering to meet the following emissions requirements: Output Regulation Regulation from initial setpoint measured by changing load from 5% load to 50% load or 50% load to full load in either direction. Initial setpoint tolerance is measured at 50% load. A minimum load of 5% of the output current on the +5.1 V output (125 mA) is required to maintain proper regulation. Overload Protection Fully protected against short circuit and output overload. Short circuit protection is cycling type power limit Overvoltage Protection Built in with firing point set per ratings table. OVP firing reduces voltage to less than 50% of nominal voltage in 50 ms. Voltage Adjustment Factory set with fixed resistors to maximize reliability. Efficiency 70% minimum at full rated load, nominal input voltage.
