GSC25 GLOBAL PERFORMANCE SWITCHERS FEATURES: • Industry’s smallest 25W switcher • 2.50 x 4.00 x 0.86” • Approved to UL1950, IEC950 and CSA22.2-234 Level 3, EN60950 • EMI FCC Class B, CISPR22B • Overvoltage protection standard • For medical version, see p. 80 • marked to LVD Input Protection SPECIFICATIONS: Internal AC fuse provided on all units. AC Input Inrush Current 90-264Vac, 47-63Hz single phase. Inrush is limited by internal thermistor. The inrush at 230Vac, averaged over the first AC half-cycle under cold start conditions will not exceed Input Current 32A. Maximum input current at minimum 120Vac, 60Hz with full rated output load is 0.6A. Temperature Coefficient 0.03%/ºC typical on all outputs. Hold-up Time 15 mSec minimum from loss of AC input at full load, nominal line Environmental (115Vac). Designed for 0 to 50°C operation at full rated output power; derate output current and total output power by 2.5% per °C above 50°C. See Output Power Environmental and Packaging Specifications (p. 11) for additional Normal continuous output power is 25W, 28W peak for 60 sec. maximum information. duration, 10% duty cycle. Factory set to begin power limiting at approximately 30W. EMI/EMC Compliance All models include built-in EMI filtering to meet the following emissions Output Regulation requirements: 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 EMI SPECIFICATIONS COMPLIANCE LEVEL tolerance is measured at 50% load. A minimum load of 5% of the output Conducted Emissions EN55022 Class B; FCC Class B current is required to maintain proper regulation.

Reverse Voltage Protection Safety All outputs protected against inadvertent application of reverse voltage up Condor D.C. Power Supplies, Inc. declares under our sole responsibility to 1 times rated current of the reversed output. that all GSC models are in conformity with the applicable requirements of Overvoltage Protection EN60950 following the provisions of the Low Voltage Directive 73/23/ Built in with firing point set per ratings table. OVP firing reduces voltage to EEC. All GSC models are approved to UL1950, CSA22.2 No. 234 Level less than 50% of nominal voltage in 50mSec. 3, IEC950 and EN60950. Voltage Adjustment Factory set with fixed resistors to maximize reliability. Efficiency 70% minimum at full rated load, nominal input voltage. Turn-on Time Less than 1 second at 115Vac, 25ºC (inversely proportionate to input voltage and thermistor temperature). Condor D.C.
