The MCR Hardwired Series provides excellent noise filtering and surge protection to safeguard connected equipment against damage, degradation or malfunction. This protection, combined with the excellent voltage regulation inherent to the ferroresonant design, can significantly increase the mean time between failures (MTBF) of protected equipment. The MCR is a perfect choice where dirty power caused by impulses, swell, sags, brownouts or waveform distortion can lead to costly downtime due to damaged equipment.
