Notes
1
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.
