AC Adapter Item Inrush current Efficiency Output Ratings DC output voltage Noise + Ripple Output current Input rated voltage Input current Dynamic Output Characteristics Turn-on delay time Hold up time Over Voltage Protection (OVP) Short circuit protection Electrostatic discharge (ESD) Dielectric Withstand Voltage Primary to secondary Leakage current Regulatory Requirements Specification The maximum inrush current will be less than 150Ap-p when the adapter is connected to 115Vac(60Hz) and 230Vac(50Hz) respectively. It should provide an efficiency of 83% minimum, when measured at maximum load under 115V(60Hz). +18.0V ~ 20.0V including the effects of line voltage variation, load current, ripple and noise 400mVp-p (20MHz bandwidth) for resistor load 0 ~ 4.74A 100 / 240V 1.5A @ 90Vac, 1.15A @ 180Vac 5 sec. (Max) 10ms min. (115 Vac, input full load) 29 V Output can be shorted without damage 15kV (at air discharge) 8kV (at contact discharge) 3000Vac (4242Vdc) 10mA for 1 second 100uA max (240Vac, 60Hz) Internal filter meets; 1. FCC class B requirements. 2. VDE 243/1991 class B requirements. 3. CISPR 22 Class B requirements. 3. VCCI class II requirements. Power Management Power Saving Mode Standby Mode Waiting time specified by the System Standby value or the operating system elapses without any system activity. Or When the computer is about to enter Hibernation mode (e.g. during a battery-low condition), but the Hibernation file is invalid or not present. Hibernation Mode When customized functions for power management are set to Hibernation and the corresponding action is taken. Display Standby Mode Keyboard, built-in touchpad, and an external PS/2 pointing device are idle for a specified period. Hard Disk Standby Mode Hard disk is idle within a specified period of time Phenomenon The Sleep indicator lights up All power shuts off The display shuts off Hard disk drive is in standby mode.
