SPF-500 Datasheet, PDF (1/2 Pages) SL Power Electronics – 500-1000 Watts Single Output, Forced Current Sharing
SPF-500, SPF-750, SPF-1000 Commercial Series
500-1000 Watts Single Output, Forced Current Sharing
FEATURES:
• 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
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) compen-
sates 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.
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.
OPTIONS:
Consult factory for available options.
