Notes
1. Replace the input line fuse with the same type and rating.
Recommended: 2A/250V slow-blow fuse.
2. Electrical strength/isolation is 2200 VDC from the input of the supply to
ground for 60 seconds.
3. All measurements are made directly at the terminals of the power supply.
4. 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 power supply with a 0.1 µF ceramic
capacitor. The instruments’ probe ground band must make direct contact
with the output return or common terminal of the supply to prevent erro-
neous noise measurements.
5. MTBF is calculated using the parts stress method in MIL-HDBK 217F
(ground benign, T
A
= +25°C).
6. Output voltage tolerance is measured under nominal load conditions.
7. Line regulation is measured under nominal load conditions as the input
voltage is varied from 85 to 265 VAC.
9. Load regulation is measured at 115 VAC or 230 VAC. For single output
models, load regulation is measured while output current is varied from
0% to 100% of full load. With multiple 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.
10. 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.
11. The FLU1-50, FLU3-50 and FLU1-60 series are approved to UL1950
(File E140439), CSA22.2 No.234 (File LR52335) and
EN60950/IEC950/DIN VDE 0805 (TÜV Licenses R9271543, R9171470,
and R9271468).
