GSC20 Commercial 20 Watt Single Output Global Performance Switchers FEATURES: Industry’s smallest 20 W switcher Business-card size (2.0 x 3.5 x 0.71”) Approved to UL60950, CSA-C22.2 No. 60950, EN60950, IEC60950 with CB Certificate EMI FCC Class B, CISPR22B Overvoltage protection standard marked to LVD SPECIFICATIONS: Ac Input Efficiency 90-264 Vac, 47-63 Hz single phase. 70% minimum at full rated load, nominal input voltage. Efficiency increases as output voltage increases. Input Current Maximum input current at minimum 120 Vac, 60 Hz with Input Protection full rated output load is 0.6 A. Internal ac fuse provided on all units. Hold-up Time Inrush Current 15 ms minimum from loss of ac input at full load, nominal Inrush is limited by internal thermistor. The inrush at 230 line (115 Vac). Vac, averaged over the first ac half-cycle under cold start conditions will not exceed 32 A. Output Power Normal continuous output power is 20 W, 24 W peak for Temperature Coefficient 60 s maximum duration, 10% duty cycle. Factory set to 0.03%/°C typical on all outputs. begin power limiting at approximately 28 W. Environmental Output Regulation Designed for 0 to 50°C operation at full rated output Regulation from initial setpoint measured by changing power; derate output current and total output power by load from 5% load to 50% load or 50% load to full load in 2.5% per °C above 50°C. See Environmental Specifica- either direction. Initial setpoint tolerance is measured at tions on next page. 50% load. A minimum load of 5% of the output current is required to maintain proper regulation. EMI/EMC Compliance All models include built-in EMI filtering to meet the Overload Protection following emissions requirements: Fully protected against short circuit and output overload.
