Notes:

1. Line regulation is measured for an input voltage change of ±10%.

2. Load regulation is measured from 10% load to full load.

3. When measuring output ripple & noise, it is recommended that an exter-

nal capacitor (1 µF to 10 µF) be placed from each output to common.

The typical noise specified for the IG220-12 is 100 mV P - P.

4. The unit will meet the radiated and conducted EMI specifications

with the addition of external components as shown in the con-

nection diagram on page 3.

5. Operation at no-load will not damage these units. However, they

may not meet all specifications.

6. It is recommended that a fuse be used on the input of a power

supply for protection. See the Model Selection table above for

the correct rating.
