SPECIFICATIONS
Ac Input
85-264 Vac, 47-63 Hz single phase.
EMI/EMC Compliance
All models include built-in EMI filtering to meet emissions requirements:
Input Current
Maximum input current 3.7 A at 90 Vac, 60 Hz with full rated load. Input cur-
rent harmonic content meets the requirements of IEC1000-3-2 Class A for all
load conditions.
Hold-upTime
25 ms minimum from loss of ac input at full load, nominal line (115 Vac).
Minimum Load: No minimum load required

COMPLIANCE LEVEL
EN55022 Class B; FCC Class B

EN61000-4-5, 1 kV diff., 2 kV com.
Output Power
250 W fan cooled, 180 W convection. See chart for models under 12 V.
Overload Protection
Fully protected against short circuit and output overload. Short circuit protec-
tion is cycling type power limit or foldback type depending on model and
output. Recovery after fault is automatic. Individual output current limits are
a function of load distribution and degree of overload.
Output Noise
0.5% rms, 1% pk-pk, 20 MHz Bandwidth, differential mode. Measured with
noise probe directly across output terminals of the power supply.
Transient Response
Main Output–500 μs typical response time for return to within 0.5% of final
value for a 50% load step change, Di/Dt< 0.2 A/μs. Maximum voltage devia-
tion is 3.5%.
Remote Sense
Provided as a standard feature. Capable of compensating for 0.25 V total of
cabling losses in voltage.
Overvoltage Protection
Built in on all models. Output voltage decay is dependent upon loading.
Voltage Adjustment
Main output ±5%.
Efficency
Minimum 80% on 12-48 V units, 75% on 5 & 3.3 V units at full rated load.
Input Protection
Internal ac fuses provided on all models. Fuses do not blow on overload or
short circuit—fuses blow only if catastrophic failure occurs in the unit.
Inrush Current
Inrush 240 Vac is less than 37 A, averaged over the first ac half-cycle under cold
start conditions. Limiting provided by internal thermistors.
Fan Output
An additional 12 Vdc, 250 mA output suitable for powering a dc fan is included in
all models.
Thermal Shutdown
Provided as a standard feature. Designed to protect unit from prolonged over
temperature.
Power Fail
TTL or CMOS compatible output goes low (<0.5 V) 8 ms before output voltage
drops more than 4% below nominal voltage upon loss of ac power. The signal is
factory set to trip when input power can no longer sustain the output.
Temperature Coefficient
0.03% / °C typical on all outputs.
Leakage Current
70μA under normal conditions (132 Vac @ 60 Hz).
Maximum under single fault conditions (264 Vac @ 60Hz), 250 μA.
Power Good
TTL/CMOS compatible output goes high more than 100 ms after V1 reaches the
under voltage threshold and should assure that sufficient energy is stored in the
input
section to provide normal power fail/shutdown. The signal will fall to a low state
(<0.5 V) when V1 goes below 95% of the rated voltage.
External Off
TTL/CMOS compatible input shuts down power converter. A logic high (>2.7 V
with 400 uA source) shuts down the power converter. A logic low (<0.5 V) or an
open circuit allows the supply to run. 3.3 V & 5 V models require 25 mA source.
All specifications are typical at nominal input, full load at 25 O C unless otherwise stated
