SPECIFICATIONS
Output Noise
Ac Input
0.5% rms, 1% pk-pk, 20 MHz bandwidth, differential mode. Measured with noise
probe directly across output terminals of the power supply.
85-264 Vac, 47-63 Hz single phase.
Input Current
Transient Response
Maximum input current at 120 Vac, 60 Hz with full rated output load: 1.7 A
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
Voltage Adjustment
Built-in potentiometer adjusts voltage 5% on outputs 1 ꢀ 2.
55 W continuous, 70 W peak. Peak ratings are for 60 s maximum duration,
10% duty cycle. During peak load condition, output regulation may exceed
total regulation limits.
EMI/EMC Compliance
All models include built-in EMI filtering to meet the following emissions require-
ments:
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. See output ratings chart for
additional notes or conditions. Factory set to begin power limiting at ap-
proximately 75 W.

Efficiency
70% at full rated load, nominal input voltage, depending on model and load
distribution.
Commercial Leakage Current
0.7 mA 254 Vac @ 60 Hz input.
Input Protection
Internal ac fuse provided. Designed to blow only if a catastrophic failure oc-
curs in the unit.
Commercial Safety
Approved to UL1950, CSA22.2 No. 234 Level 3, IEC950 and EN60950. UL file
#E135803 commercial; CSA #LR46516 all models. All dc outputs are SELV under
normal and single fault conditions.
Inrush Current
Inrush is limited by internal thermistors. Inrush at 240 Vac under cold start
conditions will not exceed 34 A.
Medical Leakage Current
35 μA 254 Vac @ 60 Hz input.
Temperature Coefficient
0.03%/°C typical on all outputs.
Medical Safety
Environmental
Approved to UL2601, CSA22.2 No. 601 Level 3 and IEC601. 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.
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.
All specifications are typical at nominal input, full load at 25OC unless otherwise stated
