OUTPUT
POWER
(MAX.)
Measured with 10 μF tantalum capacitor and 1 μF ceramic capacitor across
output.
di/dt = 0.1 A/1 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.
Units should be characterised within systems. External components required.
Input fusing is recommended based on surge current and maximum input
current.
This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
Simulated source impedance of 12
Active high remote on/off option is available (standard product is active low),
designate with the suffix ‘FHT’ e.g. BXB75-48S05FHTJ. Consult factory for
further details and options.
Start-up into resistive load.
The ‘J’ suffix indicates that these parts are Pb-free (RoHS 6/6) compliant.
TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special
request, please contact your local sales representative for details.
