The Pacific Power 312AMX is a linear AC power source engineered for precision testing and transient simulation across demanding power conditions. It delivers low-distortion, high-fidelity output waveforms with selectable single-phase, split-phase, or three-phase configurations. The 312AMX supports frequency conversion, harmonic testing, and programmable transient simulations with full 5 kHz power bandwidth when paired with the UPC-32 controller.
