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. OPTIONS: Option “C”, Cover: Limits contact with power supply interior. Option “F”, Fan/Cover Assembly: Cover with integral ball-bearing fan provides proper cooling to achieve full ratings at 50°C ambient temperature. Option “G”, DC Power Good: Provides a TTL “1” open collector when output #1 is above 4.6 V nominal. Option “V”, Fan/Cover Assembly: Low profile, end venting cover with integral ball-bearing fan.
