Overview
The Eaton 9PX8KG2 is an 8,000VA / 8,000W online double-conversion uninterruptible power supply (UPS) designed to protect critical IT infrastructure, enterprise servers, networking equipment, and data center systems. It delivers true sine wave output and provides continuous power conditioning to help protect connected equipment against power interruptions and electrical disturbances.
This 9PX G2 model features a 4U rack/tower design, internal hot-swappable VRLA batteries, and an included NETWORK-M3 Gigabit network management card for remote monitoring and control. Hardwired input and output connections support professional installations requiring high-capacity power protection.
Key Features
- 8,000VA / 8,000W Capacity: Supports critical equipment with a power factor of up to 1.0 at 220–240V output.
- Online Double-Conversion: Provides continuous power conditioning and true sine wave output.
- Network Management Included: NETWORK-M3 Gigabit network card enables remote monitoring and management.
- Rack or Tower Installation: Space-efficient 4U chassis supports flexible installation options.
- Expandable Runtime: Supports compatible external battery modules for extended backup operation.
Power Protection and Battery Management
The UPS uses online double-conversion technology to regulate incoming power before supplying connected equipment. An internal bypass supports power continuity under specified operating conditions.
Eaton ABM+ battery management technology analyzes battery condition to help identify when replacement may be needed. The internal VRLA batteries are hot-swappable, and compatible external battery modules can be added to extend runtime.
Connectivity and Installation
The 9PX8KG2 uses a hardwired input and provides four NEMA L6-30R receptacles alongside a hardwired output connection. The included NETWORK-M3 card supports Gigabit Ethernet-based monitoring and management. USB and RS-232 interfaces are also provided for local communication.
Because this model is designed for high-capacity electrical installations, input supply, circuit protection, wiring, and output requirements should be verified by a qualified electrician before installation.
