Filtering:
a) Voice Band Noise: Complies with Telcordia GR-947-CORE.
1. Output noise according to Telcordia GR-947-CORE is <38 dBrnC typical at normal input and
30% to 80% of rated load for more than one solar converter.
2. Psophometric noise is ≤ 2 mV typical at 30% to 80% of rated load for more than one solar
converter.
b) Wide Band Noise: Complies with Telcordia GR-947-CORE.
1. Wideband noise emission is <250 mV peak to peak between 0 Hz to 100 MHz, and <50 mV rms
in any 3 kHz band 10 KHz to 20 MHz.
