Notes:
1. 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 single output units and from
each output to common for dual output units. For noise sensitive applications, the use
of 1.5 µF capacitors will reduce the output ripple.
2. Dual output units may be connected to provide a 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.
3. 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 <1.0⍀ at 100 kHz) capacitor be
mounted close to the converter. For 5V input units a 4.7 µF is recommended, for 12V
and 24V units a 2.2 µF.
4. 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.
