SPF-500, SPF-750, SPF-1000 Commercial Series 500-1000 Watts Single Output, Forced Current Sharing FEATURES: • • • • • • • SPECIFICATIONS: INPUT Ac Input: 90-264 Vac continuous range, 47 to 63 Hz. 750 W units fused for 15 A. 1000 W units fused for 20 A. Power Factor: 0.99 typical at full load. Meets EN61000-3-2 Class A. Inrush: Cold start ac current is less than 50 A at 115 Vac and 100 A at 230 Vac for 500 W and 750 W models; 90 A at 115 Vac and 180 A at 230 Vac for 1000 W models. Limited by thermistor. Brownout Protection: Continuous range units hold regulation to 85 Vac. Holdup Time: 20 ms minimum after removal of power at full load. Efficiency: 75% typical. Ac Power Fail: Provides TTL “0” 5 ms before output voltage goes out of regulation band upon loss of power. OUTPUT Adjustability: User adjustable ±5% minimum. Line & Load Reg: ±1% over ac input range and 0 to 100% load change. Ripple & Noise: Less than 1% p-p or 100 mV, whichever is greater. Remote Sense: Compensates for 250 mV total line drop. Open sense lead protection. (See Redundancy, below.) Temperature Coefficient: 0.02% per degree C. Stability: 0.1% over 8 hours after 30 minutes warm-up. Transient Response: Output voltage returns to within 1% in less than 500 µs for a 50% load change. Peak transient does not exceed 5%. Overload Protection: All outputs are protected against overload and short circuit. Automatic recovery upon removal of fault. Overvoltage Protection: Protects load against power supply induced overvoltage. Trip point is factory set so that output voltage cannot exceed 136% of nominal. Remote Inhibit: Contact closure to the negative sense line or a TTL level “0” turns off dc output. Dc Power Good (5 V Outputs): Provides a TTL “1” open collector when output is above 4.6 V nominal. Redundancy: External OR-ing diodes and forced current sharing provide “N+1” capability. Remote sense (+S) compensates for additional 0.6 V diode voltage drop. When the current sharing terminal is connected between units, current sharing remains within 10% of the unit’s full output current rating. Reverse Voltage: Protected against reverse voltage up to supply current rating. ENVIRONMENTAL Thermal Protection: Shuts down power supply if overheated. Automatic recovery. Forced current sharing for N +1 redundancy Universal ac input 0.99 typical power factor Low ripple and noise Dc power good and ac power fail signals True remote inhibit Monotonic turn-on and turn-off Temperature Range: 0° to 50°C at full ratings. Safety Agencies: Most models are approved to UL1950; CSA 22.2 #234; IEC 950 and TÜV EN60950, Class 1 SELV., CE 72/23/ EEC/93/68EEC (low voltage directive). Conducted RFI: Meets FCC Part 15, Class A; EN55022 Class B. Output Isolation: Isolated from ground 50 Vdc. Cooling: Self cooled by internal ball-bearing fans.
