Notes:
1. When measuring output ripple, it is recommended that an external 0.47
μF
ce-
ramic 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 sup-
plied 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 protec-
tion. See the table above for the correct rating.
