Notes

1

Measured with 10µF tantalum capacitor and 1µF ceramic capacitor across

the output.

2

Iout = Inom; delta Iout = ±25% Iout (max), di/dt = 1A/µs.

3

Input fusing is required based on surge and maximum input current.

4

This product is only for inclusion by professional installers within other

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

5

Input reflected ripple current test set-up uses a Pi filter; 220µF, 12µH,

100µF.

6

Start-up into resistive load.

7

Active high remote on/off is available (standard product is active low),

designate with the suffix ‘H’ e.g. BXF250-48S3V3H.

8

Units should be characterised within systems. External components and

filtering required.
