Notes
1 Recommended input fusing is a 20 A HRC 250 V rated fuse.
2 Measured with external filter. See Application Note 208 for details.
3 Start-up into resistive load.
4 Peak to peak measured without external Pi filter. Significant reduction
possible with external filter. See Application Note 208 for details.
5 This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
6 Active-low remote ON/OFF option is also available. Please add the suffix ‘-R’
to the part number, e.g. IBC32AEN4896-REJ.
7 Maximum output power at maximum input voltage.
8 Efficiency at 100% maximum output voltage.
9 After an input overvoltage latch off, the input voltage must be returned to 55
V or lower for unit to restart.
10 TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special
request, please contact your local sales representative for details.
