Notes

1

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

0.75 lo max. and 0.75 lo max. to 0.5 lo max. Deviation varies by model, see

Longform Datasheet.

2

The EXQ125 meets level A and level B conducted emissions only with

external components connected before the input pins to the converter.

See Application Note 118.

3

Recommended input fusing is a 5 A HRC 200 V 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. See Application Note 118.

6

Start-up into resistive load.

7

Contact the factory for Modified Standard pin length products.
