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

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
