Notes:

1. When measuring output ripple, it is recommended that an external 0.47 µF ceramic capacitor

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. Dual output units may be connected to provide a 24 VDC or 30 VDC output. To do this, connect

4. 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 <1.0

at 100 kHz) capacitor be mounted

close to the converter. For 12V input units a 10.0 µF is recommended, for 24V a 4.7 µF and

for 48V units a 2.2 µF.

5. 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.
