Notes:
1. Load regulation is measured for an output change of 20% to
100%.
2. When measuring output ripple, it is recommended that an external
0.33 µF ceramic capacitor be placed from the +Vout pin to the -Vout
pin. For noise sensitive applications, the use of 0.47 µF capacitors will
reduce the output ripple.
3. Operation at no-load will not damage these units. However, they
may not meet all specifications.
4. The converter should be connected to a low ac-impedance source.
An input source with a highly inductive impedance may affect the
stability of the converter. In applications where the converter output
loading is high and input power is supplied over long lines, it may
be necessary to use a capacitor on the input to insure start-up.
In this case, it is recommended that a low ESR (ESR <1.0Ω at 100 kHz)
capacitor be mounted close to the converter. For 5V input units a 2.2
µF is recommended, for 12V input units, a 1.0 µF, and for 24V input
units, a 0.47 µF.
5. Dual output units may be connected to provide a 10 VDC, 24 VDC 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.
