Notes:
1. Output load regulation is specified for a load change of 20% to 100%.
2. When measuring output ripple, it is recommended that an external ceramic capacitor (approx 10 µF)
be placed from the +Vout pin to the -Vout pin for single output units and from each output to common
for dual output units.
3. All 3.3, 5 and ±5 VDC output models may be operated to +85ºC ambient with an unobstructed airflow
of 3.6 ft/S (1.1 m/S).
4. The 5V, 12V and 24V input units do not require external components to operate, but the use of an
input capacitor (10 µF) may enhance performance in some applications. An output capacitor (1.0 µF
to 10 µF) may be used to reduce ripple. The 48V input models require an input capacitor of 4.7 uF to
47 uF (dependent upon the application).
5. Dual output units may be connected to provide a 10V, 24V or 30 VDC output. To do this, connect the
load across the positive (+Vout) and negative (-Vout) outputs and float the output common.
6. It is recommended that a fuse be used on the input of a power supply for protection. See the table above
for the correct rating.
