Power Protection and Conditioning Overview
The MCR Hardwired Series is designed to provide superior noise filtering and surge protection, safeguarding connected equipment from potential damage, degradation, or misoperation. It features SolaHD’s patented ferroresonant design, which enhances voltage regulation and increases the Mean Time Between Failure (MTBF) of protected equipment. This series is ideal for environments with dirty power conditions, such as impulses, swells, sags, brownouts, and waveform distortion, which can lead to costly downtime.

Key Features

• ±3% output voltage regulation
• Noise attenuation: 120 dB common mode, 60 dB transverse mode
• Surge protection compliant with ANSI/IEEE C62.41 Class A & B Waveform
• Functions as a step-up or step-down transformer
• Harmonic filtering and galvanic isolation for exceptional circuit protection
• 25-year typical MTBF with no maintenance required

Applications

• Industrial automation and control equipment
• Machine tools
• Computer loads and electronic equipment
• Robotics
• Semiconductor fabrication equipment
