Providing single- or 3-phase output in range of power from 3,000–9,000 VA, BLC Series provides clean sine wave output. Multi-pulse input transformer helps minimize harmonic distortion and maximize power factor. Along with over-temperature, short-circuit, and voltage fold-back protections, features include voltage and frequency adjustment, line drop compensation, phase angle adjustment, as well as external sync and output on/off with remote power connection.
