AC Adapter Item Vendor & model name Input Requirements Maximum input current (A, @90Vac, full load) Nominal frequency (Hz) Frequency variation range (Hz) Input voltage range (Vrms) Inrush current Efficiency Output Ratings (CV mode) DC output voltage Noise + Ripple Load Output Ratings (CC mode) DC output voltage Constant current mode 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 Delta ADP-65DB Specification 1.5 A @ 110Vac 1.0 A @ 240Vac 50-60 47-63 90-270 The maximum inrush current will be less than 50A and 100A when the adapter is connected to 115Vac and 230Vac respectively. It should provide an efficiency of 80% minimum, when measured at maximum load under 115Vac. 19V 300mVp-pmax (20 MHz bandwidth) 0(min) 3.16A(max) 19V +/-1.0V for CV mode 3.6 +/- 0.3A 3 sec (@ 115Vac) 5ms (@115Vac, Full load) 24V 3.9A max can be protected and output can be shorted without damage 15KV (at air discharge) 8KV (at contact discharge) 3000Vac 0.25 mA max. (@ 254Vac, 60Hz) Safety Requirements: 1.The subject product rated 100-120V 60Hz must be listed under UL 1950 and certified with SCA Standard C22.2 No.950. 2.The subject product rated 200-240V 50Hz must comply with low voltage directive 73/23EEC. EMI Requirements: 1.The subject product rated 100-120V 60Hz must meet the EMI requirements of FCC part 15, Subpart B for Class B Digital Device and get FCC Certification before marketing into USA and Canada. 2.The subject product rated 200-240V 50Hz must meet the EMC Directive 89/ 336/EEC. 3.The subject product rated 100-120V must meet the VCCI-2 EMI requirements.
