Part Number System with Options

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.

CAUTION: Hazardous internal voltages and high temperatures.

Ensure that unit is not user accessible.

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.
