Notes:
1. When measuring output ripple, it is recommended that an external 0.47 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.
2. Transient recovery is measured to within a 1% error band for a load step change of
75% to 100%.
3. Operation at no-load will not damage these units. However, they may not meet all speci-
fications.
4. 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.
5. 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 12V input units, a 15 μF is recommended; for 24V &
48V units a 4.7 μF.
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.
