SPECIFICATIONS
Inhibit
Ac Input
Inhibit signal is pulled to the V1 output common to reduce average output voltage
to less than 5% of nominal.
85-264 Vac, 47-63 Hz single phase.
Input Current
EMI/EMC Compliance
All models include built-in EMI filtering to meet the EMC requirements of IEC601-1.
Unless otherwise stated, all tests are done at full load and 115 and 230 Vac input.
2.8 A line current maximum, at 90 Vac, 60 Hz with full rated load, power factor
.99 typical, .96 minimum. Input current harmonic content meets the require-
ments of IEC1000-3-2.

Efficiency
Minimum 80% at full rated load with 230 Vac Input. Approximately 3% less at
115 Vac.
Hold-Up Time
EN61000-4-11
Outputs will remain within regulation limits for 25 ms minimum from loss of
ac input at full load, 10 ms before Power Fail indication.
Inrush Current
Inrush 240 Vac is less than 37 A, averaged over the first ac halfcycle under cold
start conditions. Limiting provided by internal thermistors.
Output Regulation
Total regulation is the maximum deviation from the nominal voltage for all
steady state loading conditions.
Fan Output
An additional 12 Vdc, 250 mA output suitable for powering a dc fan is included in
all models. The fan output is both current limited and thermally protected.
Overload Protection
Fully protected against short circuit and output overload. Short circuit protec-
tion is cycling type power limit.
Thermal Shutdown
Provided as a standard feature. Designed to protect unit from prolonged over
temperature.
Minimum Load
No minimum load required to maintain output specifications.
Power Fail
Output Noise
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.
0.5% rms, 1% pk-pk, 20 MHz Bandwidth, differential mode. Measured with
noise probe directly across output terminals of the power supply.
Power Good
Transient Response
TTL / CMOS compatible output goes high more than 100 ms after V1 reaches
regulation and should assure that sufficient energy is stored in the input section to
provide normal power fail/shutdown.
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%.
Medical Approvals
Remote Sense
All models are Certified to be in compliance with the applicable requirements of
UL2601-1, CSA-C22.2 No. 601.1, IEC601-1/60601-1.
Standard feature on all models, includes open sense lead protection.
Overvoltage Protection
Built in on all models.
Leakage Current
70 μA, 132 Vac @ 60 Hz normal conditions. Single fault conditions, 130 μA, 254 Vac
@ 50 Hz.
Input Protection
Internal ac fuses provided on both lines on all units.
