Can PCR-LE series output a three-phase line-to-line voltage of 440 V at 60 Hz?

Yes, it can. Although PCR-LE series is a single-phase output model, a three-phase output is possible by using three PCR-LE units and the optional 3P05-PCR-LE (three-phase output driver).
PCR-LE2 series, on the other hand, is a model that can switch between single-phase output, three-phase output, and single-phase three-wire output.
