Derating Curve
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. For
noise sensitive applications, the use of 3.3 µF capacitors will reduce the
output ripple.
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 specifications.
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 3.3 µF
is recommended and for 24V units a 2.2 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.
