Note: Certain applications may require the installation of external fuse in front of the input.
PU SERIES APPLICATION NOTES:
EXTERNAL CAPACITANCE REQUIREMENTS:
Output filtering is required for operation. A minimum of 10uF is needed. Output capacitance may be
increased for additional filtering, not to exceed 220uF.
To meet the reflected ripple requirements of the converter, an input impedance of less than 0.5ohm
from DC to 250KHz is required.
We Can Offer EMC-Filter According To EN55011/22 Class B.
Negative Outputs:
A negative output voltage may be obtained by connecting the +OUT to circuit ground and
connecting –OUT as the negative output.
