Notes:

1. The specified maximum capacitive load is for each output.

2. Cross regulation is measured with the main output set at 100% load. The second output is

varied from 75% to 100% load.

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

a low ESR 3.3 µF capcitor should be used.This capacitor should be mounted as close to the

converter as possible.

4. Transient recovery is measured to within a 1% error band for a load step change of

25%.

5. Output overload protection is provided by a fold back current limiting circuit with

auto-recovery. A long-term overload could damage the unit.

6. To meet the specified EN 61000-4-4 and EN 61000-4-5 limits, an external

capacitor must be connected across the input pins of the module. A 220 µF/100V

capacitor is recommended. This capacitor should be mounted as close to the module as

possible.

7. Operation at no load will not damage these units.

8. 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.
