Notes
1. Use of an external input line fuse is recommended:
1W series, 5V input models, use a 1.0A/125V fuse.
2W series, 5V input models, use a 1.5A/125V fuse.
1W and 2W series, all but 5V input models, use a 0.5A/125V fuse.
5W series, 5V input models, use a 2.5A/125V fuse.
5W series, 12V input models, use a 1.5A/125V fuse.
5W series, 24V input models, use a 1.0A/125V fuse.
5W series, 48V input models, use a 0.5A/125V fuse.
2. Peak-to-peak and RMS metering equipment must have a 20 MHz fre-
quency response with probes and cables that maintain a frequency
response of 20 Hz to 20 MHz. Output ripple and spikes are measured
directly at the output terminals of the converter with a 0.1 µF ceramic
capacitor
The probe ground band must make direct contact with the output return
or the common terminal of the converter to prevent erroneous noise mea-
surements.
3. DC2-6 short-circuit protection: 30 seconds, max. For all other models,
protection period is unlimited.
4. MTBF is calculated using the parts stress method in MIL-HDBK 217F
(ground benign, T
A
= +25°C).
5. Dual output converters with ±12V or ±15V output can be used as single
output 24V or 30V supplies.
6. All measurements are at nominal input, full load, and +25°C unless other-
wise specified.
