The Sanrex FRS400BA60 is a robust power semiconductor module designed for high-power rectification in industrial-grade equipment. Built to Sanrex's established manufacturing standards, this module delivers reliable performance in applications requiring stable DC bus generation from AC input sources. As an obsolete component with a 99-week factory lead time for any new production runs, the FRS400BA60 represents a critical procurement challenge for maintenance teams and OEM service operations depending on Sanrex-based power conversion platforms.

The FRS400BA60 is well suited for industrial AC drives, servo amplifiers, UPS systems, welding equipment, electrochemical process rectifiers, and crane or hoist drive systems. Its high current handling capability makes it a preferred solution in heavy industrial environments where thermal stability and forward current capacity are non-negotiable. Engineers specifying replacements for aging Sanrex-based drive platforms will find this module a direct fit for legacy system refurbishment and field repair work.

Quick Reference: FRS400BA60

Key Features of the FRS400BA60:

• 400A continuous forward current rating for high-power industrial rectification duty cycles
• 600V repetitive peak reverse voltage (VRRM) providing adequate margin in 480VAC three-phase systems
• Sanrex-standard isolated base construction for simplified heatsink mounting and electrical isolation
• Low forward voltage drop optimized to minimize conduction losses and reduce thermal stress at rated current
• Compact module footprint enabling straightforward drop-in replacement in existing Sanrex-platform drive cabinets
• Designed for compatibility with standard Sanrex thermal interface and bus bar configurations common in legacy industrial equipment

The FRS400BA60 was officially discontinued by Sanrex, and any new factory production carries a 99-week lead time—an unworkable timeline for most maintenance and repair operations. Facilities running Sanrex-based drive systems or rectifier cabinets cannot afford extended downtime waiting on factory builds. Sourcing from a stocking distributor with verified new OEM inventory is the only practical path to keeping production lines operational. ATI Accurate Technology specializes in exactly this scenario: sourcing and stocking obsolete, long-lead, and hard-to-find power semiconductor modules so your procurement team has a reliable alternative when the factory cannot deliver.

ATI Accurate Technology is headquartered in Palmetto, Florida and stocks power semiconductors including IGBTs, thyristors, diodes, and rectifier modules from leading manufacturers.
