48 VDC INPUT – MULTIPLE OUTPUT

These series are particularly suitable for critical, “can’t fail”; mobile; or transportable systems. All models share the same foot- print and can include current sharing for redundancy (consult factory for details). Optional DC power fail, covers, and fan/cover assemblies are available. These series are form-fit compatible with the 9” SC, MAX, MTC, and MPS Series DCT-250 DBX-275 DCT-350 DCX-350 Featuring:

  • Over 3 watts/in3 power density
  • Meets international safety requirements
  • All outputs regulated ±1%
  • High peak currents for motor starting
  • System air and self-cooling options
  • Available in dual AC input range STANDARD DBX SERIES STANDARD DCT, DCX SERIES Option F Option C 250, 275, 350 WATTS MULTIPLE OUTPUT 24/28 AND 48 VDC INPUT

DC, DCT, DCX, and DPS models 40.8-60 Vdc range, internally fused for 15 A. Efficiency: 70 to 75% typical. OUTPUT Adjustability: All outputs user adjustable ±5% minimum. Line & Load Reg: ±1% over DC input range and 0 to 100% load change, except DPS models hold ±3% on +5 V output (preprogrammed slope). Multiple output units require a minimum load of 10% on the +5 V output when drawing full load on the auxiliary outputs. Ripple & Noise: Less than 1% p-p or 100 mV, whichever is greater. Remote Sense (Output #1): 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 (Output #1): Protects load against power supply induced overvoltage. Trip point is factory set so that output voltage cannot exceed 136% of nominal. Peak Output Current: Dual current ratings define continuous and peak currents. The peak current shown can be delivered for a maximum period of 30 seconds. Remote Inhibit: Contact closure to the negative sense line drops output power to nominal zero. Redundancy (DPS only): External OR-ing diodes and slope program current sharing on output #1 provide “N+1” capability. Remote sense (+S) compensates for additional 0.6 V diode voltage drop. 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, Subpart J, Class A; EN55022 Class B; CISPR 22 Class B. Cooling: 30 CFM required to achieve full ratings. Output Isolation: Isolated from ground 50 Vdc, except 100 Vdc for models rated 48 Vdc output. 250, 275, 350 WATTS 9”x 5”x 2.5” DCT-250,350, DBX-275, DCX-350 DC OUTPUT Barrier strip #6-32 screws 3/8” centers Bus bars #10-32 screws FUNCTION LOCATION NOTES CONNECTOR J1-1(+ S) Output #1 Sense J1-2 (– S) Output #1 Sense Rtn J1-3 Reference to J1-2 Inhibit J1-4 (IH) Short to J1-2 *Optional function STATUS AND CONTROL AMP MTA type #640456-4 pin header (locking) Remote Sense DC Power Good* FUNCTION –48 Vdc +24 Vdc CONNECTOR TB1- –48 Vdc Input +24 Vdc Return TB1- –48 Vdc Return +24 Vdc Input TB1- Safety Ground Safety Ground Barrier strip #6-32 screws 3/8” centers OPTIONS: Option “C”, Cover: Limits contact with power supply interior.
