APC MX5000 5000VA Matrix-UPS 5KVA 208/240V Head Unit Isolation Module Smartcell

APC MX5000 5000VA Matrix-UPS 5KVA 208/240V Head Unit Isolation Module Smartcell

The APC MX5000 is a high-capacity 5000VA / 5KVA uninterruptible power supply system from APC's Matrix-UPS line, designed to deliver large-scale battery backup and power conditioning for critical infrastructure. The Matrix-UPS platform uses a modular architecture, combining a central head/control unit with separate isolation and battery stack modules that can be configured and expanded to match power protection needs. This listing is sold as-is for parts or repair — the unit is untested, has cosmetic damage, and is missing covers.

Applications

The APC Matrix-UPS series was designed for large enterprise, data center, and industrial environments requiring robust, scalable power protection for servers, networking equipment, and other critical loads. Introduced in the 1990s, the Matrix-UPS line was notable for its modular design: rather than a single fixed unit, customers could combine head units, isolation modules, and battery stacks to build a power protection system sized to their exact load requirements. The MX5000's 5KVA capacity and 208/240V operation made it well-suited to high-density server rooms and mid-sized data centers of the era. The inclusion of the AP9608 Web/SNMP management card allowed remote monitoring and management over a network — a valued feature for operations teams managing distributed infrastructure. Today these systems are sought by facilities maintaining legacy equipment, by engineers who need parts to repair existing Matrix-UPS installations, or by buyers looking to harvest the AP9608 management card or other modular components.
