85-264 Vac, 47-63 Hz single phase.
2.8 A line current maximum, at 90 Vac, 60 Hz with full rated load, power factor
.99 typical, .96 minimum. Input current harmonic content meets the require-
ments of IEC1000-3-2.
150 W with convection cooling, 180 W with fan cooling. Peak ratings are for
60 s maximum duration, 10% duty cycle.
Minimum 80% at full rated load with 230 Vac Input. Approximately 3% less at
Outputs will remain within regulation limits for 25 ms minimum from loss of
ac input at full load, 10 ms before Power Fail indication.
Total regulation is the maximum deviation from the nominal voltage for all
steady state loading conditions.
Fully protected against short circuit and output overload. Short circuit protec-
tion is cycling type power limit.
No minimum load required to maintain output specifications.
0.5% rms, 1% pk-pk, 20 MHz Bandwidth, differential mode. Measured with
noise probe directly across output terminals of the power supply.
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%.
Standard feature on all models, includes open sense lead protection.
Built in on all models.
Internal ac fuses provided on both lines on all units.
Output Voltage is adjustable +/- 5% with user adjustable potentiometer.
0.03% / °C typical on all outputs.
Less than 2% overshoot at turn-on under all conditions, less than 1% over-
shoot at turn-off under all conditions.

Inhibit signal is pulled to the V1 output common to reduce average output voltage
to less than 5% of nominal.
All models include built-in EMI filtering to meet the EMC requirements of IEC601-1.
Unless otherwise stated, all tests are done at full load and 115 and 230 Vac input.

Inrush 240 Vac is less than 37 A, averaged over the first ac halfcycle under cold
start conditions. Limiting provided by internal thermistors.
An additional 12 Vdc, 250 mA output suitable for powering a dc fan is included in
all models. The fan output is both current limited and thermally protected.
Provided as a standard feature. Designed to protect unit from prolonged over
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.
TTL / CMOS compatible output goes high more than 100 ms after V1 reaches
regulation and should assure that sufficient energy is stored in the input section to
provide normal power fail/shutdown.
All models are Certified to be in compliance with the applicable requirements of
UL2601-1, CSA-C22.2 No. 601.1, IEC601-1/60601-1.
