SINGLE OUTPUT, HOT SWAP MODEL OUTPUT RATING PWR OUT SPH-1200-24 24V @ 50A 1200 SPH-1200-28 28V @ 42A 1200 SPH-1200-48 48V @ 25A 1200 STANDARD SPH SERIES The SPH-1200 series provides low- cost, highly reliable, N+1 redundant hot swap power for critical applications. These 1200-watt single-output power supplies include an integral fan and are available with a front panel and handle for front access in sub-system racks or without handles for embedded applications. Power factor correction, OR-ing diodes, and current sharing make the SPH series an ideal choice for communi- cations and data processing systems utilizing distributed power or redundant power architecture. SPH-1200 Featuring:

  • Diode isolated output for hot swap
  • “Zero wire” slope program current sharing for redundancy
  • High power density: 5 W/cu. in.
  • Industry standard DIN connector
  • Universal AC input
  • 0.99 typical power factor
  • DC power good and AC power fail signals
  • True remote inhibit
  • Monotonic turn-on and turn-off SEE TRS (RACK SYSTEM)

SPECIFICATIONS: ALL MODELS INPUT AC Input: 105-264 Vac continuous range, 47 to 63 Hz. Internally fused for 20 A. Power Factor: 0.99 typical at full load. Meets EN61000-3-2. Inrush: Cold start ac current is less than 75 A at 115 Vac and 150 A at 230 Vac for 8 ms typical. Limited by thermistor. Holdup Time: 16 ms minimum after removal of power at full load. Efficiency: 80% minimum AC Power Fail: Provides TTL “0” 5 ms before output voltage goes out of regulation band upon loss of AC power. Brownout Protection: Holds regulation to 85 Vac for 30 seconds maximum. OUTPUT Adjustability: User adjustable ±5% minimum. Line Regulation: ±0.2% Load Regulation: ±2% (Slope Program) from 0 to 100% load change. Turn On Delay: 1 second typical Output Rise Time: (from 10% to 90%) 20 ms typical. Ripple & Noise: Less than 1% p-p, measured at 20 MHz bandwidth. 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 3%. Overload Protection: Electronic current limit, 120% maximum. Overvoltage Protection: Protects load against power supply induced overvoltage. Trip point is factory set so that output voltage cannot exceed 136% of nominal. Requires AC input to be cycled to reset. Remote Inhibit: Contact closure or a TTL level “0” turns off DC output. DC Power Good: Provides a TTL “0” open collector when output is above 90% of nominal. Maximum pull-up voltage 30 Vdc; maximum sink current, 10 mA. Redundancy: Built-in OR-ing diode, slope program current sharing, and DIN blade connector provide “hot swap” and “N+1” capabilities. Current sharing remains within 10% of the unit’s full output rating given 0.2% initial accuracy in the output voltage setting. Status Indicators: Green LED on the front panel indicates normal operation (ACPF high and DCPG low) ENVIRONMENTAL Thermal Protection: Shuts down power supply if overheated. Automatic recovery. Temperature Range: 0° to 50°C at full ratings. Safety Agencies: Approved to UL1950; CSA 22.2 #950; IEC 950 and TÜV EN60950, Class 1 SELV, CE 73/23/EEC//93/68/EEC (low voltage directive). Conducted RFI: Meets FCC Part 15, Subpart J, Class A; EN55022 Class B; and CISPR 22 Class B. Cooling: Self-cooled by internal ball-bearing fan. 13.44”x 5”x 4.03” SPH-1200 FUNCTION LOCATION NOTES CONNECTOR Output Z12 D14 Z16 D18 (+) to Polarity Voltage Z4 D6 Z8 D10 (-) to Polarity FUNCTION LOCATION NOTES CONNECTOR DC Power Good Z20 Reference to AC Power Fail D22 to Common Inhibit Z24 LOCATION 115 VAC 230 VAC CONNECTOR Z32 Line Line 1 D30 Neutral Line 2 See Below Z28 Safety Ground Safety Ground AC INPUT (105-264 VAC Continuous Range) DC OUTPUT Eurocard Connector - Male DIN 41 612 Level 1- Type H STATUS AND CONTROL See above OPTIONS Option “R”, Rack Mount Panel: Special panel is required for rack mounting.
