UPS Intelligence & Control Modules
APC Symmetraâ„¢, Symmetra PX, and Liebert Nfinity UPS systems rely on intelligent control modules to manage system logic, power-module coordination, communications, fault reporting, redundancy, and overall operational stability. These modules act as the command center of the UPS, continuously monitoring system health and coordinating the functions required to maintain dependable load protection.

Available modules include Main Intelligence Modules (MIM), Redundant Intelligence Modules (RIM), and manufacturer-specific UPS control modules. They are designed for Symmetra Power Array, RM, LX, PX, and Liebert Nfinity platforms, providing critical system control, fault management, communications, and redundancy capability.
In systems equipped with separate main and redundant intelligence modules, the redundant module supports continued monitoring and control if the primary module becomes unavailable. Some UPS platforms, such as the Symmetra LX, use the same module part number in both the main and redundant positions.
Whether replacing a failed module, restoring a legacy UPS, or maintaining a redundant configuration, these professionally refurbished control modules help restore system intelligence, operational stability, communications, and reliability. Each refurbished module is inspected, reconditioned, and functionally tested before shipment.
