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
Transient Response
Maximum input current at 120 Vac, 60 Hz with full rated output load: 1.3 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
Remote Sense
Provided as a standard feature on single-output models.
40 W continuous, 50 W peak. 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 main output voltage 5%.
Overload Protection
EMI/EMC Compliance
All models include built-in EMI filtering to meet the
following emissions requirements:
Fully protected against short circuit and output overload.
Short circuit protection is cycling type power limit on outputs 1 & 2; foldback
type on output 3. Recovery after fault is automatic. See output ratings chart
for additional notes or conditions.

Efficiency
70% at full rated load, nominal input voltage, depending on model and load
distribution.
Turn-on Time
Less than 1 second at 120 Vac, 25°C (inversely proportional to input voltage
and thermistor temperature).
Commercial Safety
Approved to UL1950, CSA22.2 No. 950, IEC950, EN60950. All dc outputs are SELV
under normal and single fault conditions.
Input Protection
Internal ac fuse provided. Designed to blow only if a catastrophic failure oc-
curs in the unit.
Medical Leakage Current
The maximum leakage current is as follows:
Test Condition
120 Vac @ 60 Hz input
264 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.
Normal Single
25 μA
40 μA
Fault
35 μA
60 μA
Temperature Coefficient
0.03%/°C typical on all outputs.
Medical Safety
Approved to UL2601-1, CSA22.2 No. 601 Level 3 and EN60601-1. 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 con-
nection without additional isolation. All dc outputs are SELV under normal and
single fault conditions.
Environmental
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.
All specifications are typical at nominal input, full load at 25OC unless otherwise stated
