SPECIFICATIONS
Ac Input
85-264 Vac, 47-63 Hz single phase.
Input Current
Maximum input current at 120 Vac, 60 Hz with full rated output load: 1.3 A
Hold-Up Time
20 ms minimum from loss of ac input at full load, nominal line (115 Vac).
Output Power
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.
Overload Protection
Fully protected against short circuit and output overload.
Short circuit protection is cycling type power limit.
Recovery after fault is automatic. Factory set to begin power limiting at ap-
proximately 55 W. See output ratings chart for additional notes or conditions.
Overvoltage Protection.
See output ratings chart.
Efficiency
69-77% at full rated load, nominal input voltage, depending
on model.
Turn-on Time
Less than 1 s at 120 Vac, 25°C (inversely proportional to input voltage).
Input Protection
Requires external ac line fusing. A 2.5 A, 250 V rated fuse with I2t > 20 is
recommended.
Inrush Current
Inrush is limited by internal thermistor. Inrush at 240 Vac under cold start
conditions will not exceed 34 A.
Temperature Coefficient
0.03%/°C typical on all outputs.
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. See Environmental and
Packaging Specifications on next page.
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.
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%.
EMI/EMC Compliance
All models include built-in EMI filtering to meet the
following emissions requirements:

Commercial Leakage Current
60 μA single fault; 60 Hz input.
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.
Medical Leakage Current
35 μA , 254 Vac 60 Hz input.
Medical Safety
Approved to UL2601, CSA22.2 No. 601 Level 3, IEC601.
UL file E116994; CSA #LR46516. The output(s) are intended for safety earthed Sig-
nal 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.

A. Units should be allowed to warm up/operate under non-condensing conditions before application of power. Derate output
current and total output power by 2.5% per °C above 50°C. For operation in a confined space, moving air may be required. Under
all conditions, the cooling vs. load profile should be such that heat sinks and/or heatsink temperatures do not exceed 90 °C for
extended periods.
B. Shock testing—half-sinusoidal, 10 ± 3 ms duration, ± direction, 3 orthogonal axes, total 6 shocks.
C. Random vibration—10 to 2000Hz, 6dB/octave roll-off from 350 to 2000Hz, 3 orthogonal axes. Tested for 10 min./axis operating
and 1 hr./axis non-operating.
