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 is 0.85 A.
Hold-up Time
15 ms minimum from loss of ac input at full load, nominal line (120 Vac).
Output Power
Normal continuous output power is 28 W, 32 W peak for 60 s maximum dura-
tion, 10% duty cycle. Factory set to begin power limiting at approximately 35
W.
Overload Protection
Fully protected against short circuit and output overload. Short circuit pro-
tection is cycling type power limit.
Output Noise
0.5% rms, 1% pk-pk, 20 MHz bandwidth, differential mode. Measured with
scope probe directly across output terminals of the power supply with load
terminated with 0.1 μF capacitor.
Overvoltage Protection
Built in with firing point set per ratings table. OVP firing reduces voltage to
less than 50% of nominal voltage in 50 ms.
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.
Medical EMI/EMC Compliance
All models include built-in EMI filtering to meet the following emissions require-
ments:
EMI SPECIFICATIONS COMPLIANCE LEVEL
Conducted Emissions EN55011 Class B; FCC Class B
Static Discharge EN61000-4-2, 6 kV contact, 8 kV air
RF Field Susceptibility EN61000-4-3, 3 V/meter
Fast Transients/Bursts EN61000-4-4, 2 kV, 5 kHz
Surge Susceptibility EN61000-4-5, 1 kV diff., 2 kV com.
Line Frequency Harmonics EN61000-3-2 Class A
Earth Leakage Current
Leakage current measured in the Gnd wire connection when measured per
EN60601-1 or UL2601-1 is as follows:
Medical Normal SingleFault Test Test
Model Leakage Leakage Voltage Method
Voltage Adjustment
Factory set with fixed resistors to maximize reliability.

264 Vca/50 Hz
UL2601-1
IEC60601-1
Efficiency
70% minimum for the 5.1 V model at full rated load, nominal input voltage.
Efficiency increases as output voltage increases.
Input Protection
Internal ac fuse provided on all units. Designed to open only if a catastrophic
failure occurs in the unit.
Inrush Current
Inrush limited by internal thermistor. The inrush at 230 Vac, averaged over the
first ac half-cycle under cold start conditions will not exceed 32 A.
Medical Medical Safety
SL Power Electronics Corp. declares under our sole responsibility that all GSM
models are in conformity with the applicable requirements of UL2601-1 Patient
Care Equipment, CSA-C22.2 No. 234 (with additional tests to C22.2 No. 601.1 per
T.I.L. CA-08), EN60601-1.
Minimum Load Requirement
5% of full load rating
Transient Response 3.5% max. dev. 50% load step at 0.2 A/μs. Recovery to
0.5% within 500 μs.
All specifications are typical at nominal input, full load at 25 O C unless otherwise stated
