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.
