Model Selection Guide

Mechanical Dimensions

Notes:

1. Load regulation is measured for an output change of 20% to 100%.

2. When measuring output ripple, it is recommended that an external 0.33 µF

ceramic capacitor be placed from each output to the common pin. For noise

sensitive applications, the use of 3.3 µF capacitors will reduce the output ripple.

3. Operation at no-load will not damage these units. However, they may not meet

all specifications.

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 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 <1.0

 at 100 kHz) capacitor

be mounted close to the converter. For 5V input units a 2.2 µF is recommended;

a 1.0 µF for 12V input units; and for 24V input models, a 0.47 µF.

5. 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.

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.
