Notes

1

di/dt = 0.1A/µs, Vin = 48VDC, Tc = 25°C, load change = 0.5 lo max. to

0.75 lo max. and 0.75 lo max. to 0.5 lo max.

2

The EXQ50 meets level A and level B conducted emissions only with

external components connected before the input pins to the converter.

See Application Note 120 for details.

3

Recommended input fusing is a 3.15A HRC 200V rated fuse.

4

This product is only for inclusion by professional installers within other

equipment and must not be operated as a stand alone product.

5

Measured with no external Pi filter. Significant reduction possible with

external filter.

6

Start-up into resistive load.

7

Active low remote On/Off is available. Standard product is active high.

When ordering active low parts, designate with the Suffix '-R', e.g

EXQ50-48S3V3-R.

8

This parameter is calculated at worst case line, load, temperature and

initial settings.

9

This is inclusive of the output trim range. If 6.0% trim-up is used, for

example, then only 4.0% output sense is available.
