Vertiv APS5KPWRMOD2 5kVA Hot-Plug Redundant UPS Power Module

Overview

The Vertiv APS5KPWRMOD2 is a 5,000VA plug-in UPS power module designed for the Liebert APS modular uninterruptible power supply platform. Rated at 5 kVA on a single-phase 208V output, it installs as a hot-pluggable, redundant unit — meaning you can add or replace the module under load without taking the system offline. That capability is the defining reason to deploy modular UPS architecture in the first place: scheduled maintenance and capacity upgrades happen without a maintenance window that touches production systems.

Key Features

• 5,000VA Capacity: Each APS5KPWRMOD2 module contributes 5 kVA to the shared UPS frame. In an N+1 redundancy configuration, one module acts as the standby — if an active module fails, the standby carries the load instantly with no transfer gap. Size your total frame capacity to include the redundant module so you don't inadvertently deplete your margin.
• Hot-Plug / Hot-Swap Architecture: The module slides into the Liebert APS chassis without shutting down the UPS or dropping the connected load. This is critical in 24/7 environments — data centers, network operations centers, and security infrastructure rooms — where any power interruption has cascading consequences. Swap a failed module during business hours rather than scheduling a late-night outage.
• Single-Phase, 208V Output: Matched to standard North American single-phase 208V distribution, this module pairs directly with server, networking, and security equipment drawing from a 208V PDU or branch circuit. Confirm your load equipment accepts 208V input before deploying — do not assume 120V tolerance.
• Plug-In Module Form Factor: The modular physical design lets you start with the capacity you need today and add modules as power demand grows, without replacing the entire UPS frame. This scales more cost-effectively than replacing a monolithic UPS when your network infrastructure or camera count increases.

Integration and Compatibility

The APS5KPWRMOD2 is designed for the Vertiv Liebert APS modular UPS platform. Verify chassis compatibility and total frame slot count against your specific APS frame model before ordering — not all APS frames accept the same number of power modules or support the same redundancy configurations. Consult the Vertiv Liebert APS frame documentation for supported module combinations and maximum load ratings per chassis.

For facilities running mixed IP camera infrastructure alongside compute and networking gear, a modular UPS approach lets you add protected capacity incrementally as the camera count grows — a more manageable capital expense than over-provisioning a fixed-capacity unit at initial installation.

Frequently Asked Questions

Q: What UPS platform does the APS5KPWRMOD2 work with?

A: The APS5KPWRMOD2 is designed for the Vertiv Liebert APS modular UPS chassis. Verify your specific APS frame model supports this module before ordering.

Q: Can I install the APS5KPWRMOD2 while the UPS is running?

A: Yes. The APS5KPWRMOD2 supports hot-plug installation, meaning the module can be added or replaced while the UPS frame is powered and carrying a load — no shutdown required.

Q: What output voltage does the APS5KPWRMOD2 provide?

A: The APS5KPWRMOD2 delivers 208V single-phase output at up to 5,000VA capacity.

Q: How many APS5KPWRMOD2 modules can I install in one chassis?

A: The number of supported modules depends on the specific Liebert APS chassis model. Consult the Vertiv Liebert APS frame documentation for slot capacity and supported configurations.

Q: Is the APS5KPWRMOD2 suitable for N+1 redundancy?

A: Yes. The module is rated as a redundant, hot-plug unit. In an N+1 deployment, one module serves as standby and takes over instantly if an active module fails, keeping the connected load protected without interruption.

Eden Phillips

The hot-plug capability on the APS5KPWRMOD2 is the spec I always lead with when engineers are evaluating whether modular UPS makes sense over a fixed-capacity unit. In a 5 kVA increment you get the ability to swap a failed module under full load — that changes the maintenance calculus entirely for any facility that cannot tolerate even a brief power interruption to its protected equipment.

Technical Highlights:

• 5,000VA Per Module: Each module contributes a discrete 5 kVA block to the frame's total capacity, making capacity planning straightforward — add modules as load grows rather than replacing the entire UPS infrastructure.
• Hot-Plug Redundancy: The plug-in module design supports live insertion and removal while the chassis is under load. In an N+1 configuration, this means a failed module triggers automatic failover to the standby before you've even dispatched a technician.
• 208V Single-Phase Output: Matched to standard single-phase 208V branch circuits common in North American data center and IDF closet environments — no step-down transformer required for equipment already rated 208V.

Deployment Considerations:

• Confirm chassis compatibility before ordering — the APS5KPWRMOD2 is specific to the Liebert APS modular frame and not a universal UPS module. Mixing incompatible modules in a frame is a real-world failure mode worth avoiding at the procurement stage.
• When planning N+1 redundancy, account for the standby module slot in your total frame capacity calculation. A frame fully loaded with active modules has no redundancy margin — size the chassis to carry N active modules plus at least one standby.

The APS5KPWRMOD2 is the right fit for IT closets and security infrastructure rooms running 208V single-phase distribution where the operational cost of a UPS maintenance window exceeds the cost premium of modular architecture — network operations centers, 24/7 monitoring facilities, and high-density camera recording environments are the clearest deployment match.
