SPECIFICATIONS
Ac Input
Output Noise
85-264 Vac, 47-63 Hz single phase.
0.5% rms, 1% pk-pk, 20 MHz bandwidth, differential mode. Measured with noise
probe directly across output terminals of the power supply.
Input Current
Maximum input current at 120 Vac, 60 Hz with full rated output load: 2.3 A
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%.
Startup/shutdown overshoot less than 3%.
Hold-Up Time
20 ms minimum from loss of ac input at full load, nominal line (115 Vac).
Output Power
Remote Sense
Provided as a standard feature on single-output models.
80 W continuous, 110 W with air flow. Peak ratings are for 60 s maximum
duration, 10% duty cycle. During peak load condition, output regulation may
exceed total regulation limits.
Voltage Adjustment
Built-in potentiometer adjusts voltage 5% on outputs 1 ꢀ 2.
Overload Protection
Fully protected against short circuit and output overload. Short circuit protec-
tion is cycling type power limit on outputs 1 ꢀ 2; foldback type on outputs 3
ꢀ 4. Recovery after fault is automatic. Factory set to begin power limiting at
120 W. See output ratings chart for additional notes or conditions.
EMI/EMC Compliance
All models include built-in EMI filtering to meet the following emissions
requirements:

Efficiency
70% at full rated load, nominal input voltage, depending on model and load
distribution.
Input Protection
Line Frequency Harmonics
Internal ac fuse provided. Designed to blow only if a catastrophic failure oc-
curs in the unit.
Commercial Leakage Current
0.7 mA 254 Vac @ 60 Hz input.
Inrush Current
Inrush is limited by internal thermistors. Inrush at 240 Vac under cold start
conditions will not exceed 34 A.
Commercial Safety
Approved to UL1950, CSA22.2 No. 234 Level 3, IEC950 and EN60950. UL file
#E135803 commercial; CSA #LR46516 all. The output(s) are intended for safety
earthed Signal Output and Intermediate Circuits only. All dc outputs are SELV
under normal and single fault conditions.
Temperature Coefficient
0.03%/°C typical on all outputs.
Environmental
Medical Leakage Current
35 μA 254 Vac @ 60 Hz input.
Designed for 0 to 50°C operation at full rated output power; derate output
current and total output power by 2.5% per °C above 50°C. See Environmen-
tal and Packaging Specifications on next page.
Medical Commercial Safety
Approved to UL2601-1, CSA-C22.2 No. 601.1 Level 3 and IEC601.1. UL file E116994;
CSA #LR46516. The output(s) are intended for safety earthed Signal Output and
Intermediate Circuits only. The output(s) are not acceptable for patient connection
without additional isolation. All dc outputs are SELV under normal and
single fault conditions.
Power Fail (optional)
TTL- or CMOS-compatible output goes low (< 0.5 V) 5 ms before output
voltage drops more than 4% below nominal voltage upon loss of ac power.
The signal is factory set to trip on 84 to 94 Vac brown-out depending upon
incoming line impedance and distortion. Other settings are available to the
user through adjustment of built-in potentiometer (consult factory for as-
sistance). For Power fail option, add -PF after model number.
All specifications are typical at nominal input, full load at 25OC unless otherwise stated
