Filtering:
a)
Peak-peak voltage is ≤ 250mV at 1-100MHz and normal output voltage.
b)
Psophemetic noise voltage is ≤ 2mV between 5-100% of the maximum load (output voltage > 56 VDC).
c)
Wideband noise is < 20mV rms between 25HZ-20kHz (test according to ETS300132).
d)
Output noise according to Telcordia GR-947-CORE: < 38 dBrnC (between 5-100% of the maximum load, output voltage >
56 VDC).
•
Ripple Attenuation: Ripple attenuation is better than +24dB, input to output and f < 360Hz.
