Mechanical Notes:

Notes:

1. When measuring output ripple, it is recommended that an external 3.3 µF ceramic capacitor be

for dual output units.

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.

4. An external 220 µF/100V capacitor connected across the input pins is required to meet

EN61000-4-4 and EN61000-4-5.

5. Dual output units may be connected to provide a 10, 24 or 30 VDC output. To do this, connect the

6. 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 24V input units a 4.7 µF is

recommended; and for 48V units a 2.2 µF.

7. 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.
