The 63-23-730-8 is a 3000VA Power Line Conditioning provides excellent noise filtering and surge protection to safeguard connected equipment from damage, degradation or misoperation. Combined with the excellent voltage regulation inherent to SolaHD's Ferroresonant design, the MCR can increase the actual mean time between failures (MTBF) of protected equipment. The MCR hardwired series is a perfect choice where dirty power, caused by impulses, swells, sags, brownouts and waveform distortion can lead to costly downtime because of damaged equipment.
