* Peak output current rating = 5.0A (<60 seconds, duty cycle <10%).
† Peak output current rating = 3.0A (<60 seconds, duty cycle <10%).
§ Peak output current rating = 2.0A (<60 seconds, duty cycle <10%).
Notes
1. Replace the input line fuse with the same type and rating.
Recommended: 2A/250V slow-blow fuse.
2. The sum of primary and auxiliary output currents from triple
output models -1AD through -4AD must not exceed 5.0A.
3. Hi-pot isolation is 2200 VDC from the input of the supply to
ground for 60 seconds.
4. All measurements are made directly at the terminals of the
power supply.
5. Peak-to-peak and RMS metering equipment must have a 20
MHz frequency response with probes and cables that main-
tain a frequency response of 20 Hz to 20 MHz. Output rip-
ple and spikes are measured directly at the output terminals
of the power supply with a 0.1 µF ceramic capacitor. The
probe ground band must make direct contact with the output
return or common terminal to prevent erroneous noise mea-
surements.
6. MTBF is calculated using the parts stress method in MIL-
HDBK 217F (ground benign, T
A
= +25°C).
7. Output voltage tolerance is measured under nominal load
current conditions.
8. Line regulation is measured under nominal load conditions
as the input voltage is varied from 85 to 265 VAC (ac-input
models) or from 36 to 75 VDC (dc-input models).
9. Load regulation is measured at 115 VAC or 230 VAC. For
single output models, load regulation is measured while out-
put current is varied from 0% to 100% of full load. With mul-
tiple output models, the output under test is brought to 60%

of nominal load; load current is then varied +40%/-30% of nominal while other outputs
are held at nominal load conditions.
Cross-regulation is tested by changing the load on the primary output from 50% to
100% of nominal load while measuring the voltage change on the auxiliary output
under test.
