These series are particularly suitable for
critical, “can’t fail”; mobile; or transportable
systems. All models share the same footprint and can include current sharing for
redundancy (consult factory for details).

SPECIFICATIONS: ALL MODELS
INPUT
DC Input: DB, DBT, and DBX models 20-32 Vdc range, internally fused for 20 A. 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.
Consult factory for other available options.
