2 / 9 page  MINT1275 275W Single Output Medical Series www.slpower.com MINT1275 REV 1.2, 15-JAN-13 2 General Specifications (continued) Inrush Current 264Vac, cold start: will not exceed 50A Signals AC Power Fail, DC OK, Inhibit, Current Share Input Fuses F1, F2: 5A, 275VAC fuses provided on all models Overload Protection 120%-150% of rating, Hiccup Mode Earth Leakage Current <275μA@264Vac, 60Hz, NC; <400µA SFC Short Circuit Protection Provided - no damage will occur if the output is shorted. Hiccup Mode. Efficiency 92% typical Overvoltage Protection OVP latch at 110%-130% of rated output voltage. Output Power 275W continuous, with 200 lfm airflow, 180W convection cooled – See chart for specific voltage model ratings. Switching Frequency PFC: Variable, 30kHz - 400kHz Main Converter: Variable 30-250kHz, 65-70kHz at full load. Transient Response 500μS typ. for return to within 0.5% of nominal, 50% load step. i/t <0.2A/µS. Max Volt Deviation = 3% Isolation Input-Output: 4000Vac, 2 x MOPP Input-Ground: 1800Vac, 1 x MOPP Output-Ground: 1500Vac Ripple and Noise See chart Operating Temperature -10°C to +70°C Start Up at -40°C, full load Output Voltage See chart Temperature Derating Derate output power linearly above 50°C to 50% at 70°C Voltage Adjustability +/-5% from nominal Storage Temperature -40°C to +85°C Minimum Load Not required Altitude Operating: -500 to 10,000 ft. Non-operating: -500 to 40,000 ft. Total Regulation +/- 3%. See chart Relative Humidity 5% to 95%, non-condensing Vibration Operating: 0.003g ²/Hz, 1.5grms overall, 3 axes, 10 min/axis Non-Operating: 0.026g ²/Hz, 5.0grms overall, 3 axes, 1 hr/axis Shock Operating: Half-sine, 20gpk, 10ms, 3 axes, 6 shocks total Non-Operating: Half-sine, 40 gpk, 10 ms, 3 axes, 6 shocks total Dimensions W: 3.0” x L: 5.0” x H: 1.38” Safety Standards EN/CSA/UL/IEC 60601-1, 3 rd Edition Weight 325g MTBF 465,000 hours, 275W load, 25 °C Ambient, 110Vac input Auxiliary Signals AC Power Fail: Goes LOW with 5mS warning before loss of DC output after loss of AC power. DC OK: Open collector logic signal goes and stays HIGH 100mS to 500mS after main output reaches regulation. Inhibit: Connect to inhibit pin (J201 pin 5) to output common to inhibit the DC output. Fan Output: 12V @ 1A Remote Sense: Compensates for up to 250mV drop in load lines. Current Share: Forced Current Sharing provided for up to 5 units connected in parallel. |
