SPECIFICATIONS:
INPUT
Ac Input: 90-264 Vac continuous range, 47 to 63 Hz. Internally
fused for 15 A.
Power Factor: 0.99 typical at full load. Meets EN61000-3-2 Class A.
Inrush: Cold start ac current is less than 65 A at 115 Vac and
130 A at 230 Vac. Limited by thermistor.
Brownout Protection: Holds 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 ac power.
OUTPUT
Adjustability: Outputs #1 and 2 user adjustable ±5% minimum.
Output #3 tracks #2; initial accuracy ±4%. Output #4 user
adjustable ±5% minimum, or +5% only if voltage is 5.2 V.
Line & Load Reg: Outputs #1, 2, and 4 hold ±1% over ac input
range and 0 to 100% load change. Output #3 requires 20%
minimum load on outputs #2 and 3 to hold ±4%.
Ripple & Noise: Less than 1% p-p or 100 mV, whichever is greater.
Remote Sense (Outputs #1 and 2): Compensates for 250 mV
total line drop. Open sense lead protection. (See Redundancy.)
Temperature Coefficient (Outputs #1, 2, and 4): 0.02% per
degree C.
Stability: 0.1% over 8 hours after 30 minutes warm-up.
Transient Response (Outputs #1, 2, and 4): 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 (Outputs #1 and 2): Protects load
against power supply induced over voltage. 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 or a
TTL level “0” turns off dc outputs.
Dc Power Good: Provides a TTL “1” when output #1 is above
4.6 V nominal.

Redundancy: External OR-ing diodes and forced current
sharing on output #1 provide “N+1” capability. Remote Sense
(+S) compensates 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.
Requires minimum load of 12.5 A on +5V.
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 A.
Output Isolation: Isolated from ground 50 Vdc.
Reverse Voltage: Protected against reverse voltage up to
supply current rating.
Cooling: Self cooled with internal ball-bearing fans.
OPTIONS:
Option “B”, Barrier Strip: Provides auxiliary output connec-
tions on #6-32 terminal screws with 3/8” centers.
AC INPUT(90-264 VAC Continuous Range)
DC OUTPUT
