GSM28 Medical 28 Watt Global Performance Switchers GLOBAL PERFORMANCE SWITCHERS FEATURES: DC Power Supplies • Industry’s smallest 28 W medically approved switcher • Compact size (4.00” x 2.59” x 0.92”) • Wide-range ac input: 85-264 Vac • Less than 25 μA leakage current @ 120 Vac • Approved to UL2601-1, EN60601-1 • EMI to FCC, CISPR 11 Class B/IEC601-1-2 • Overvoltage protection standard • RoHS Compliant Models Available (G suffix) • marked to LVD SPECIFICATIONS Ac Input 85-264 Vac, 47-63 Hz single phase. Temperature Coefficient 0.03%/°C typical on all outputs. Input Current Maximum input current at 120 Vac, 60 Hz with full rated output load is 0.85 A. 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 above 50°C. Hold-up Time 15 ms minimum from loss of ac input at full load, nominal line (120 Vac). Medical EMI/EMC Compliance All models include built-in EMI filtering to meet the following emissions requirements: Output Power Normal continuous output power is 28 W, 32 W peak for 60 s maximum duration, 10% duty cycle. Factory set to begin power limiting at approximately 35 W. Overload Protection Fully protected against short circuit and output overload. Short circuit protection is cycling type power limit. Output Noise 0.5% rms, 1% pk-pk, 20 MHz bandwidth, differential mode. Measured with scope probe directly across output terminals of the power supply with load terminated with 0.1 μF capacitor. 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 for the 5.1 V model at full rated load, nominal input voltage. Efficiency increases as output voltage increases. Input Protection Internal ac fuse provided on all units. Designed to open only if a catastrophic failure occurs in the unit.
