APC Easy UPS 3S 40kVA Three-Phase On-Line UPS

The APC Easy UPS 3S 40kVA (E3SUPS40KHB) is a true double-conversion, on-line three-phase UPS engineered to deliver continuous, regulated power to critical IT infrastructure in distributed data centers, server rooms, and industrial environments. Operating on a double-conversion topology, it continuously converts incoming AC power to DC and back to AC, eliminating the transfer time associated with line-interactive designs and providing complete isolation from utility anomalies including surges, sags, harmonics, and frequency variations. The unit supports a 40kVA / 32kW output capacity with a 0.8 power factor, three-phase input and output (3/3 configuration), and includes an integrated bypass switch for uninterrupted maintenance access.

Designed for space-constrained deployments, the Easy UPS 3S 40kVA features a compact footprint relative to its power class and ships in a tower form factor with optional rack-conversion capability. The unit incorporates an intelligent battery management system that extends battery service life through temperature-compensated charging and automatic battery self-tests. An intuitive LCD control panel provides real-time status, load, and battery metrics at a glance. Communication is handled via a built-in RS-232 interface, with an available network management card slot (AP9640/AP9641 compatible) enabling SNMP and web-based remote monitoring, graceful server shutdown integration, and integration into APC's EcoStruxure IT ecosystem.

The E3SUPS40KHB is optimized for mid-density compute environments where three-phase power distribution is already in place but individual rack or room-level protection is required. It supports adjustable output voltage settings and offers selectable input voltage ranges to accommodate varying utility conditions across international deployments. The unit is compatible with external battery modules (EBMs) for extended runtime, making it suitable for workloads requiring longer backup windows such as virtualized environments, edge computing nodes, telecommunications equipment rooms, and healthcare IT systems.

Ideal for

• Providing double-conversion power protection for mid-size server rooms and distributed data center nodes running virtualized workloads on three-phase infrastructure
• Protecting telecommunications and network equipment in carrier-grade edge facilities where utility power quality is variable or unreliable
• Supporting healthcare IT environments — including imaging systems and electronic health record servers — that require zero-transfer-time power continuity
• Delivering conditioned three-phase power to industrial automation controllers and SCADA systems in manufacturing or process-control facilities
• Serving as a room-level UPS in retail or branch-office IT closets consolidating three-phase power for POS servers, network switches, and storage appliances
• Enabling extended runtime protection for edge computing infrastructure when paired with APC-compatible external battery modules in locations with frequent or prolonged outages
