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. ∆i/∆t<0.2 A/μs. Maximum voltage deviation is 3.5%.

Startup/shutdown overshoot less than 3%.

Remote Sense

Provided as a standard feature on single-output models.

Voltage Adjustment

Built-in potentiometer adjusts voltage ±5% on outputs 1 & 2.

EMI/EMC Compliance

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

requirements:

Ac Input

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

Input Current

Maximum input current at 120 Vac, 60 Hz with full rated output load: 2.3 A

Hold-Up Time

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

Output Power

80 W continuous, 110 W with air flow. Peak ratings are for 60 s maximum

duration, 10% duty cycle. During peak load condition, output regulation may

exceed total regulation limits.

Overload Protection

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

tion is cycling type power limit on outputs 1 & 2; foldback type on outputs 3

& 4. Recovery after fault is automatic. Factory set to begin power limiting at

120 W. See output ratings chart for additional notes or conditions.

Overvoltage Protection

Main outputs: 124% ± 12% typical.

Efficiency

70% at full rated load, nominal input voltage, depending on model and load

distribution.

Input Protection

Internal ac fuse provided. Designed to blow only if a catastrophic failure oc-

curs in the unit.

Inrush Current

Inrush is limited by internal thermistors. Inrush at 240 Vac under cold start

conditions will not exceed 34 A.

Temperature Coefficient

0.03%/°C typical on all outputs.

Environmental

Designed for 0 to 50°C operation at full rated output power; derate output

current and total output power by 2.5% per °C above 50°C. See Environmen-

tal and Packaging Specifications on next page.

Power Fail (optional)

TTL- or CMOS-compatible output goes low (< 0.5 V) 5 ms before output

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

The signal is factory set to trip on 84 to 94 Vac brown-out depending upon

incoming line impedance and distortion. Other settings are available to the

user through adjustment of built-in potentiometer (consult factory for as-

sistance). For Power fail option, add -PF after model number.
