POWER
(MAX.)
Measured with 10µF tantalum capacitor and 1µF ceramic capacitor across
output.
di/dt = 0.1A/1µs, 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.
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. BXB50-48S05FHT. Consult
factory for further details and options.
