1. For FLU and MDU models, replace the input line fuse with the same type
and rating. Recommended: 2A/250V slow-blow fuse.

For the DC50 series, an external input line fuse is recommended: For
12V input models, use a 10A/125V fuse; for 24V input, use a 5A/125V
fuse; for 48V input models, use a 3A/125V fuse.
For the DC60 series, an external input line fuse is recommended: For
12V input models, use a 10A/125V fuse; for 24V input, use a 6A/125V
fuse; for 48V input models, use a 4A/125V fuse.

2. Hi-pot 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. For DC50-1 and DC50-2 models, 100 kHz noise and ripple at the 5V out-
put is 20 mVpp, typical; at auxiliary outputs, it is 5 mVpp, typical. For
DC50-3 and DC50-4 models, 100 kHz noise and ripple is 20 mVpp, typi-
cal, for all outputs.
For DC60 models, 100 kHz noise and ripple is typically 20 mVpp.
6. MTBF is calculated using the parts stress method in MIL-HDBK 217F
(ground benign, TA = +25°C).

7. Output voltage tolerance is measured under nominal load 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 minimum
to maximum input voltage (dc input models).

9. Load regulation is measured at 115 VAC or 230 VAC (ac input models) or
at nominal input voltage (dc input models) . For single output models,
load regulation is measured while output current is varied from 0% to
100% of full load. With ac-input, 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.
With dc-input models, load regulation on an output is measured from
nominal to maximum and minimum load while other outputs are held at
nominal load conditions.

§ DC50 and DC60 models include under-voltage shutdown (10% below loW
line, remote shutdown (TTL HIGH disables the unit), and external frequency
synchronization (2.8V positive pulse >9.1 µs at the synch pin).
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, FLU2-50, 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).
