Certificates of deposit, or CDs, are fixed income investments that generally pay a set rate of interest over a fixed time period.
When referenced to the local common or ground, a common-mode signal appears on both lines of a two-wire cable, in-phase and with equal amplitudes. Technically, a common-mode voltage is one-half the vector sum of the voltages from each conductor of a balanced circuit to local ground or common.
2 Answers 2. I have UPS with that same software and the AVR mode stands for automatic voltage regulation. Basically the UPS has internal regulator which is supposed to provide stable voltage when the input voltage does out of a specified range.
