GLD140 Gold Performance Medical Switchers

140 Watt Multiple Output

FEATURES:

SPECIFICATIONS:

Compact size (4.5" x 8.5" x 1.95")

Power factor corrected to IEC 1000-3-2 Class A

Documented FMEA, WCA and EMC test results

EMI compliance to CISPR11, FCC Class B, IEC601-1-2

Approved to UL2601, IEC601-1 and

CSA 22.2 No. 601.1-M90 and EN60601: 1990

marked to LVD

Ac Input

90-264 Vac, 47-63 Hz single phase.

Output Power

Continuous output power 140 W with unrestricted convection

cooling, 180 W with 150 LFM of air.

Input Current

Active Power Factor Correction circuitry assures compliance

with IEC1000-3-2, Class A. Maximum input current at minimum

input voltage and full load is 3.0 A.

Efficiency

73 – 85 % at full rated load, nominal input voltage, depending on

model and load distribution.

Hold-up Time

26 ms total. 16 ms minimum from loss of ac input at full load until

activation of the power fail signal. Output voltages remain within

specified regulation limits for an additional 9 ms minimum after

power fail activates.

Overload Protection

Fully protected against short circuit and output overload. Short

circuit protection is cycling type power limit.

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

500 μs typical response time for return to within 0.5% of final

value for a 45% load step from any load greater than 10% of full

rated load, ? i/ ? t< 0.2 A μs. Maximum voltage deviation is 3.5%.

Remote Sense

Provided as a standard feature on V1 and V2.

Overvoltage Protection

Built in on V1, 2 and 3 outputs.

Voltage Adjustment

Factory set to specified voltage with user adjustable potentiom-

eter on V1, 2 and 3. User can adjust V1, 2 and 3 at least ±5% of

nominal output voltage.

Output Regulation

Regulation for all outputs is the maximum deviation from initial

set point under all line and load conditions. Initial set tolerance is

measured with all outputs at 50 % of full rated load.

No Load Turn-On/Standby

A minimum load of 3 A on V1 is required for proper regulation. If

not met, no degradation of reliability will occur.

Temperature Coefficient

0.03% / ° C typical on all outputs.

Input Protection

Internal ac fuses provided on both lines on all units.

Inrush Current

Thermal Shutdown

Provided as a standard feature. Designed to protect unit from

prolonged over temperature.

Power Fail

TTL / CMOS compatible output goes low (<0.5 V) 10 ms before

output voltage drops more than 4% below nominal voltage upon

loss of ac power.

Power Good

TTL / CMOS compatible output rises high 100 to 300 ms after V1

reaches regulation and should assure that sufficient energy is

stored in the input section to provide normal power fail /

shutdown.

Inhibit

Inhibit signal when pulled to the V1 output common will inhibit all

output voltages.

Fan Output

An additional thermally controlled 12 Vdc, 250 mA output suitable

for powering a dc fan is included in all models (Factory installed

cover with fan makes this output unavailable).

EMI/EMC Compliance

All models include built-in EMI filtering to meet the following

requirements:

EMC SPECIFICATION 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, 3V/meter

Fast Transients / Bursts EN61000-4-4, 2 kV, 5 kHz

Surge Susceptibility EN61000-4-5, 1 kV diff., 2 kV com.

Conducted RF Susceptibility EN61000-4-6, 3V

Voltage Sags & Surges EN61000-4-11

Line Frequency Harmonics EN61000-3-2 Class A

EMC Compliance for Gold Series

Magnetic Emissions - Emissions will not exceed the limits of the

Army curve in MIL-STD-461D, RE101 when measured at 7 cm

from 30 Hz - 100 kHz over all nominal inputs and at full rated load.

Leakage Current

70 μA under normal conditions 120 Vac @ 60 Hz

Single fault conditions 280 μA, 264 Vac @ 50 Hz.

SAFETY AGENCY APPROVALS:

All models are Certified to be in compliance with the

applicable requirements of UL2601-1, CSA-C22.2 No. 601.1,

IEC 601-1/60601-1.

DESIGN VERIFICATION DOCUMENTS

The “ Gold ” series has undergone rigorous review and design

analysis. The following product documentation is available upon

request: 1. Failure Mode and Effects analysis (FMEA), 2. DVT

Data, 3. EMC / Susceptibility test results.

Inrush is limited by internal thermistors. The inrush at 240 Vac,

averaged over the first ac half-cycle under cold start conditions

will not exceed 37 A.
