Product Overview

Liebert LTS 10-32A for Dual-Bus Power Continuity

The Vertiv Liebert LTS 10-32A is an automatic transfer device developed for dual-bus power systems containing two independent AC supplies.

The two sources may consist of separate UPS systems or another compatible main and standby power arrangement. The Liebert LTS monitors both sources and supplies the connected load from the selected healthy input.

If the active source fails or moves outside the acceptable voltage or frequency range, the unit rapidly disconnects the abnormal source before connecting the alternate source.

This first-disconnect-then-connect operating method helps prevent a short circuit or source fault from extending into the standby power path.

Full DSP control provides rapid data processing for source detection, transfer decisions, operating-status indication and system protection.

The 10A and 16A versions use a compact 1U rack format, while the higher-capacity 32A configuration uses a larger rack-mounted chassis with hard-wired inputs and mixed IEC output sockets.

An optional Vertiv communication card supports remote status monitoring through SNMP-based network management.

Key Advantages

Rapid Transfer, Redundant Inputs and Intelligent Control

The Liebert LTS combines dual-source redundancy, advanced failure detection and rack-mounted deployment for business-critical IT and communication equipment.

Automatic Source Transfer

Automatically transfers the connected load to the alternate AC source when the active source fails or becomes unacceptable.

Redundant Power Design

Two independent AC inputs help maintain power to critical equipment if one source becomes unavailable.

Full DSP Control

Digital signal processing supports rapid source analysis, power-failure detection and reliable transfer control.

Compact Rack Design

The 10A and 16A models occupy only 1U, supporting installation alongside protected equipment in a standard rack.

Flexible Output Options

Model-dependent IEC C13 and IEC C19 outlets support different server, networking and communication equipment loads.

Optional Remote Monitoring

An optional communication card enables remote management and operating-status visibility through SNMP.
