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. 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 50% 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 con-
verter. 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 10
µF
is recommended,
for 12V input units, a 3.3
µF;
and for 24V & 48V 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.
