SPECIFICATIONS

Ac Input

EMI/EMC Compliance

All models include built-in EMI ﬁltering to meet emissions requirements:

85-264 Vac, 47-63 Hz single phase.

Input Current

EMI SPECIFICATIONS

COMPLIANCE LEVEL

Maximum input current 3.7 A at 90 Vac, 60 Hz with full rated load. Input cur-

rent harmonic content meets the requirements of IEC1000-3-2 Class A for all

load conditions.

Conducted Emissions GPFC250

Conducted Emissions GPFM250

Static Discharge

RF Field Susceptibility

Fast Transients/Bursts

EN55022 Class B; FCC Class B

EN55011 Class B: FCC Class B

EN61000-4-2, 6 kV contact, 8 kV air

EN61000-4-3, 3 V/meter

EN61000-4-4, 2 kV, 5 kHz

EN61000-4-5, 1 kV diﬀ., 2 kV com.

Hold-upTime

25 ms minimum from loss of ac input at full load, nominal line (115 Vac).

Minimum Load: No minimum load required

Surge Susceptibility

Output Power

Inrush Current

250 W fan cooled, 180 W convection. See chart for models under 12 V.

Inrush 240 Vac is less than 37 A, averaged over the ﬁrst ac half-cycle under cold

start conditions. Limiting provided by internal thermistors.

Overload Protection

Fully protected against short circuit and output overload. Short circuit protec-

tion is cycling type power limit or foldback type depending on model and

output. Recovery after fault is automatic. Individual output current limits are

a function of load distribution and degree of overload.

Fan Output

An additional 12 Vdc, 250 mA output suitable for powering a dc fan is included in

all models.

Thermal Shutdown

Output Noise

Provided as a standard feature. Designed to protect unit from prolonged over

temperature.

0.5% rms, 1% pk-pk, 20 MHz Bandwidth, diﬀerential mode. Measured with

noise probe directly across output terminals of the power supply.

Power Fail

Transient Response

TTL or CMOS compatible output goes low (<0.5 V) 8 ms before output voltage

drops more than 4% below nominal voltage upon loss of ac power. The signal is

factory set to trip when input power can no longer sustain the output.

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

value for a 50% load step change, Di/Dt< 0.2 A/μs. Maximum voltage devia-

tion is 3.5%.

Temperature Coeﬃcient

0.03% / °C typical on all outputs.

Remote Sense

Provided as a standard feature. Capable of compensating for 0.25 V total of

cabling losses in voltage.

Leakage Current

70μA under normal conditions (132 Vac @ 60 Hz).

Maximum under single fault conditions (264 Vac @ 60Hz), 250 μA.

Overvoltage Protection

Built in on all models. Output voltage decay is dependent upon loading.

Power Good

Voltage Adjustment

Main output 5%.

TTL/CMOS compatible output goes high more than 100 ms after V1 reaches the

under voltage threshold and should assure that suﬃcient energy is stored in the

input

section to provide normal power fail/shutdown. The signal will fall to a low state

(<0.5 V) when V1 goes below 95% of the rated voltage.

Eﬃcency

Minimum 80% on 12-48 V units, 75% on 5 & 3.3 V units at full rated load.

Input Protection

External Oﬀ

Internal ac fuses provided on all models. Fuses do not blow on overload or

short circuit—fuses blow only if catastrophic failure occurs in the unit.

TTL/CMOS compatible input shuts down power converter. A logic high (>2.7 V

with 400 uA source) shuts down the power converter. A logic low (<0.5 V) or an

open circuit allows the supply to run. 3.3 V & 5 V models require 25 mA source.

All speciﬁcations are typical at nominal input, full load at 25^OC unless otherwise stated
