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
from the +VOUT pin to the -VOUT pin for single output units and from each output to common for dual
output units. For noise sensitive applications, the use of 3.3 µF capacitors will reduce the output ripple.
4. To help meet conducted emissions requirements, the Pi filter components (C1, & L1) in the diagram
below should be used. These components should be mounted as close to the module as possible.
To meet the requirements of EN 61000-4-4 and EN 61000-4-5, an external filter capacitor (C2 in the
diagram below) is required.
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
load across the positive (+VOUT) and negative (-VOUT) outputs and float the output common.
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.
