Inhibit

Inhibit signal is pulled to the V1 output common to reduce average output voltage

to less than 5% of nominal.

EMI/EMC Compliance

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.

Ac Input

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

Input Current

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.

Output Power

150 W with convection cooling, 180 W with fan cooling. Peak ratings are for

60 s maximum duration, 10% duty cycle.

Efficiency

Minimum 80% at full rated load with 230 Vac Input. Approximately 3% less at

115 Vac.

Hold-Up Time

Outputs will remain within regulation limits for 25 ms minimum from loss of

ac input at full load, 10 ms before Power Fail indication.

Output Regulation

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

steady state loading conditions.

Overload Protection

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

tion is cycling type power limit.

Minimum Load

No minimum load required to maintain output specifications.

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

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%.

Remote Sense

Standard feature on all models, includes open sense lead protection.

Overvoltage Protection

Built in on all models.

Input Protection

Internal ac fuses provided on both lines on all units.

Voltage Adjustment

Output Voltage is adjustable +/- 5% with user adjustable potentiometer.

Temperature Coefficient

0.03% / °C typical on all outputs.

Overshoot

Less than 2% overshoot at turn-on under all conditions, less than 1% over-

shoot at turn-off under all conditions.

Inrush Current

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

start conditions. Limiting provided by internal thermistors.

Fan Output

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.

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) 8 ms before output voltage

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

Power Good

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.

Medical Approvals

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.

Leakage Current

70 μA, 132 Vac @ 60 Hz normal conditions. Single fault conditions, 130 μA, 254 Vac

@ 50 Hz.
