The Artesyn Embedded Power A0723076 is a specialized circuit breaker accessory designed for integration with the MS3500 power system. This component ensures reliable operation and protection within the power supply infrastructure.
Key electrical specifications include an adjustable DC output voltage range from 48 to 55.5VDC, with options for 110VAC or 220VAC input systems. The unit features power factor correction, achieving a nominal power factor of 0.99 at 50-100% load. It also provides adjustable battery charge control from 2A to 20A and includes 10 fuse positions, each rated up to 15A, along with up to five breaker positions for distribution.
Environmental and safety compliance are critical for this component. It meets EMC/EMI standards including FCC Class B and CISPR Class B, ESD requirements per Bellcore TR-NWT-001089, and shock and vibration standards per Bellcore TR-NWT-000063. Fire resistance is rated UL94VO, and it meets IEEE C62.41-1991 for voltage surge protection. Safety certifications include UL 1950, UL1801, and CSA C22.2 No.
