Notes:

1. Load regulation is specified for a load change of 0% to 100%. Load regulation for 3.3V output models

is ±1.0% max for a load change of 0% to 100%.

2. When measuring cross regulation, the load on one output is varied from 25% to 100% while the other

output is held at 100%.

3. When measuring output ripple, it is recommended that an external 1.0 µF ceramic capacitor be placed

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

below should be used. These components should be mounted as close to the module as possible.

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

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

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.
