The Pacific Power 308FR is a 750 VA AC power source engineered for testing, simulation, and product development applications requiring high waveform fidelity. Built on linear amplifier architecture, it delivers very low voltage distortion, minimal switching noise, and fast voltage and current slew rates. The unit supports selectable single, split, or three-phase output configurations with precise voltage programming and broad frequency coverage.
