Notes:
1. When measuring output ripple, it is recommended that an ex-
ternal 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, 24 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
converter stability. 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 24V input
units a 4.7
μF
is recommended and for 48V units a 2.2
μF.
6. It is always recommended that a fuse be used on the input of a
power supply for protection. See the table above for the correct
rating.
