Table A-6: -48Vdc power supply output characteristics
Note 1: Total regulation tolerance includes temperature change,
warmup drift and dynamic load.
Note 2: Ripple and noise were measured differentially at the
power supply using loads that were each shunted by at
least a 0.1
µ
F ceramic disc capacitor and a 10
µ
F
electrolytic capacitor, each capacitor having a band
width up to 20 MHz.
