SurgeX UPS-1440-LI-ISO - UPS w/Isolation Transformer, 1440VA 120V 2U

Product Overview

The SurgeX UPS-1440-LI-ISO is a 1440VA line interactive UPS with integrated low impedance isolation transformer, purpose-built for commercial AV system integration and IT environments where clean, conditioned power is non-negotiable. Deployed as a 2U rack-mount unit or tower, this UPS provides reliable battery backup for conference room AV systems, boardroom presentation equipment, and broadcast control rooms. As a commercial-grade UPS with isolation transformer, the UPS-1440-LI-ISO delivers true sine-wave output and 0.9 power factor while simultaneously filtering electrical noise that standard UPS units pass through unchecked. AV integrators specifying power protection for sensitive audio video equipment will find the combination of line interactive battery backup and transformer-based power conditioning in a single 2U chassis particularly advantageous.

Product Description

The SurgeX UPS-1440-LI-ISO occupies a 2U rack space and ships ready to install in standard 19-inch equipment racks. Its steel and plastic enclosure houses a line interactive UPS topology that responds immediately to power outages, keeping connected AV and IT equipment running on clean battery-derived power until mains power is restored or equipment can be safely shut down. Eight grounded AC receptacles on the rear panel provide ample capacity for conference room AV racks with displays, signal processors, control systems, and network infrastructure.

What distinguishes this unit from a standard rack UPS is the built-in low impedance isolation transformer. While the battery backup function handles outages and voltage irregularities, the isolation transformer continuously filters the AC supply, blocking high-frequency electrical noise, eliminating ground loops, and preventing harmful voltage harmonics from reaching downstream equipment. This dual-function design is especially valuable in commercial meeting spaces and government facilities where electrical infrastructure may introduce noise that degrades audio and video performance.

The UPS-1440-LI-ISO outputs a true sine wave at 0.9 power factor, making it compatible with active power factor correction (PFC) power supplies found in modern AV processors, amplifiers, and servers. The hot-swappable battery design allows maintenance technicians to replace the internal battery without powering down the connected system, reducing service disruption in mission-critical installations. An optional SNMP network card enables remote monitoring, automated shutdown scripting, and integration with network management platforms — a standard requirement in managed commercial AV and enterprise IT deployments. The advanced GUI interface provides on-site diagnostics without requiring external software. Battery tests can be scheduled automatically, ensuring readiness is confirmed without manual intervention. Additional battery cabinet options allow runtime extension for installations requiring extended holdover times beyond the internal battery capacity.

Key Features

• Line Interactive UPS Topology — Provides fast response to outages and voltage irregularities with minimal transfer time, protecting sensitive AV and IT equipment from power disruptions.
• Integrated Low Impedance Isolation Transformer — Continuously filters and conditions incoming AC power, eliminating electrical noise, ground loops, and harmonics that degrade AV system performance.
• True Sine-Wave Output — Delivers clean 120VAC sine-wave power compatible with active PFC power supplies in professional AV processors, amplifiers, and servers.
• 0.9 Output Power Factor — Higher power factor rating means more usable wattage relative to the VA rating compared to standard UPS units.
• Hot-Swappable Battery — Internal battery can be replaced without shutting down connected equipment, minimizing downtime during scheduled maintenance.
• 2U Rack-Mount or Tower Form Factor — Installs in standard 19-inch AV and IT racks or stands alone as a tower unit for flexible deployment.
• 8 Rear-Panel Grounded AC Receptacles — Sufficient outlet count for fully populated conference room AV racks including displays, switchers, control processors, and networking gear.
• Optional SNMP Network Card — Enables remote UPS monitoring, automated shutdown, and integration with network management systems for managed AV installations.
• Auto Battery Test — Scheduled automatic battery testing confirms readiness and flags battery degradation before a power event occurs.
• Expandable Runtime — Compatible with additional external battery cabinets to extend autonomy beyond internal battery capacity for mission-critical applications.

Frequently Asked Questions

What makes the UPS-1440-LI-ISO different from a standard rack UPS?

The UPS-1440-LI-ISO integrates a low impedance isolation transformer alongside the line interactive UPS circuitry. Standard UPS units protect against outages and voltage irregularities but do not filter high-frequency electrical noise or eliminate ground loops. The built-in isolation transformer continuously conditions the AC supply, making this unit appropriate for commercial AV installations where noise and harmonics affect audio and video quality.

Is the UPS-1440-LI-ISO compatible with equipment that uses active PFC power supplies?

Yes. The unit outputs a true sine wave at 0.9 power factor, which is required for correct operation of active PFC power supplies. Many modern AV processors, server-class computers, and professional amplifiers use active PFC and will not operate correctly or reliably on simulated (stepped) sine wave UPS output.

Can this UPS be monitored remotely as part of a managed AV system?

Yes, with the optional SNMP network card installed. The SNMP interface allows the UPS to be monitored and managed via standard network management platforms, supports automated graceful shutdown scripting, and is compatible with UPS monitoring software used in commercial AV and IT environments.

How is the battery replaced, and does replacement require a service shutdown?

The internal battery is hot-swappable, meaning it can be removed and replaced while the UPS remains energized and connected equipment continues to run on conditioned mains power. This is a significant advantage in commercial installations where downtime during business hours is not acceptable.

Can runtime be extended beyond what the internal battery provides?

Yes. The UPS-1440-LI-ISO supports connection of additional external battery cabinets to extend autonomous runtime beyond the internal battery capacity. This is useful in installations requiring extended holdover for graceful shutdown of complex AV or IT systems.

What rack space does the UPS-1440-LI-ISO require?

The unit occupies 2U (two rack units) in a standard 19-inch equipment rack. It can also be used in tower orientation for non-rack deployments. Unit dimensions are 20.7" D x 17.25" W x 3.39" H and the unit weighs 77 pounds, so rack structural ratings should be confirmed before installation.

What warranty and support does SurgeX provide for the UPS-1440-LI-ISO?
