[QUOTE="Rob Timmerman, post: 115897, member: 172"] Re: 3 phase amps There are some fundamental advantages to running motors on 3-phase power, completely aside from the availability of more power. For power amplifiers, while there are some advantages to the power supply design from a 3-phase input (reduced ripple and the associated storage requirements, lower input current), these advantages tend not to outweigh the requirement for 3-phase power (and higher cost) for modern amplifiers. Most modern amplifiers have maximum output power greater than the maximum input power, so are relying on internal energy storage to provide that peak output. A three-phase input only reduces the amount of storage required, but does not eliminate it. [/QUOTE]
