SPECIFICATIONS
Ac Input
85-264 Vac, 47-63 Hz single phase
Output Power
Continuous rating is 80 W with unrestricted natural convection, or 115 W with
forced convection. All models capable of 110% of rated power for 60 sec.,
10% duty cycle maximum.
Input Current
Maximum input current at 90 Vac, 60 Hz with full rated load is 1.7 A. Input
current harmonic content meets the requirements of IEC1000-3-2 for all load
conditions at 230 Vac input. Active input circuitry provides high power factor
of .96 min, .99 typical.
Inrush Current
Inrush 240 Vac is less than 37 A, averaged over thr first ac halfcycle under cold
start conditions. Limiting provided by internal thermistors.
Holdup Time
25 ms minimum from loss of ac input at full load.
Power Fail
TTL / 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 before there is insufficient power stored in the primary to sus-
tain the output. Signal can sink 1.6 mA or source 400 μA at 2.7 V (Fan-out = 1).
Efficiency
74 to 81% depending upon model
DC Output Specification
Total regulation is the maximum deviation from the nominal voltage for all
steady state loading conditions. Peak ratings are for 60 s maximum duration,
10% duty cycle. Consult factory for application assistance.
Remote Sense
Provided as a standard feature on all models. Capable of compensating for
0.25 V total of cabling losses.
Overload Protection
Fully protected against short circuit and output overload. Short circuit protec-
tion is cycling type power limit. Recovery after fault is automatic. Consult
factory for specific condition limits.
Overvoltage Protection
Built in on all models - See voltage and current chart for individual model
output limits. When OVP fires, the output converter stops providing input
power to output. Output voltage decay is dependent upon loading.
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.
DC Power Supplies
Transient Response
Main Output 500 μs typical response time for return to within 0.5% of final value
for a 50% load step change, ?i/?t<0.2 A/μs. Maximum voltage deviation is 3.5%.
Minimum Load
No minimum load required to maintain output specifications. An abrupt change in
output current from > 90% to < 2% load may cause a false triggering of the power
fail signal.
Voltage Adjustment
Main output ±5%.
Temperature Coefficient
0.03%/°C typical on all outputs.
Thermal Shutdown
Provided as a standard feature. Designed to protect unit from prolonged over
temperature.
Fan Output
An additional 12 Vdc (nominal 10.5 V), 100 mA output suitable for powering a dc
fan is included in all models. The fan output is referenced to +out. Due to high
pk-pk noise and low regulation, it is not recommended that this output be used
for any other purpose.
Input Protection
Internal ac fuse provided on all models. Fuse does not blow on overload or short
circuit -- fuse blows only if a catastrophic failure occurs in the unit.
EMI/EMC Compliance
All models include built-in EMI filtering to meet the following emissions require-
ments:
EMI SPECIFICATIONS COMPLIANCE LEVEL
Conducted Emissions EN55011 Class B; FCC Class B
Static Discharge EN61000-4-2, 6 kV contact, 8 kV air
RF Field Susceptibility EN61000-4-3, 3 V/meter
Fast Transients/Bursts EN61000-4-4, 2 kV, 5 kHz
Surge Susceptibility EN61000-4-5, 1 kV diff., 2 kV com.
Line Frequency Harmonics EN61000-3-2 Class A
Conducted RF Susceptibility EN61000-4-6, 3 V
Voltage Dips and Interruptions EN61000-4-11, Consult factory for more
details.
Leakage Current
90 μA normal conditions (132 Vac @ 60 Hz input) or 250 μA (264 Vac) single fault.
Medical Safety
All models are Certified to be in compliance with the applicable requirements of
UL 2601, CSA 22.2 No. 601.1-M90, IEC 601-1 (1988), EN 60601-1: 1990. (Consult
factory for approval status)
All specifications are typical at nominal input, full load at 25 O C unless otherwise stated
