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%.

Minimum Load

No minimum load required to maintain output specifications. An abrupt change in

output current from > 90% to < 2% load may cause a false triggering of the power

fail signal.

Voltage Adjustment

Main output ±5%.

Temperature Coefficient

0.03%/°C typical on all outputs.

Thermal Shutdown

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

temperature.

Fan Output

An additional 12 Vdc (nominal 10.5 V), 100 mA output suitable for powering a dc

fan is included in all models. The fan output is referenced to +out. Due to high

pk-pk noise and low regulation, it is not recommended that this output be used

for any other purpose.

Input Protection

Internal ac fuse provided on all models. Fuse does not blow on overload or short

circuit -- fuse blows only if a catastrophic failure occurs in the unit.

EMI/EMC Compliance

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

ments:

Ac Input

85-264 Vac, 47-63 Hz single phase

Output Power

Continuous rating is 80 W with unrestricted natural convection, or 115 W with

forced convection. All models capable of 110% of rated power for 60 sec.,

10% duty cycle maximum.

Input Current

Maximum input current at 90 Vac, 60 Hz with full rated load is 1.7 A. Input

current harmonic content meets the requirements of IEC1000-3-2 for all load

conditions at 230 Vac input. Active input circuitry provides high power factor

of .96 min, .99 typical.

Inrush Current

Inrush 240 Vac is less than 37 A, averaged over thr first ac halfcycle under cold

start conditions. Limiting provided by internal thermistors.

Holdup Time

25 ms minimum from loss of ac input at full load.

Power Fail

TTL / 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 before there is insufficient power stored in the primary to sus-

tain the output. Signal can sink 1.6 mA or source 400 μA at 2.7 V (Fan-out = 1).

Efficiency

74 to 81% depending upon model

DC Output Specification

Total regulation is the maximum deviation from the nominal voltage for all

steady state loading conditions. Peak ratings are for 60 s maximum duration,

10% duty cycle. Consult factory for application assistance.

Remote Sense

Provided as a standard feature on all models. Capable of compensating for

0.25 V total of cabling losses.

Overload Protection

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

tion is cycling type power limit. Recovery after fault is automatic. Consult

factory for specific condition limits.

Overvoltage Protection

Built in on all models - See voltage and current chart for individual model

output limits. When OVP fires, the output converter stops providing input

power to output. Output voltage decay is dependent upon loading.

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.
