AC Power
for Business-Critical Continuity™
Liebert LTS (10A & 16A)
Power Redundancy for One-way Power Supply
The LTS is an automatic transfer device, designed to provide fast automatic transfers between two independent, synchronous AC power
sources to provide continuity of AC power to critical equipment, such as information technology equipment, despite irregularities in
either of the two AC input power sources. The transfer is accomplished with sense and transfer times of less than 6 milliseconds typically.
The LTS is available as a 2 pole device, with capacities of 10, and 16 amps in a rack mount package.
Features
„ Redundancy of design for key components.
„ Preferred and Alternate Source modes.
„ Digital Signal Processor (DSP) ensuring increased
processing capability, including sensing and
operational functionality.
„ Optional SNMP card for remote monitoring
capability.
Designed For Reliability
„ Break-before-make switching eliminates
connecting together of the independent power
sources, even under faulted conditions.
„ Switched neutrals maintain isolation of the two
power sources and simplify grounding.
„ Diagnostics and transfer tests detect potential
switch failures, before the problem becomes
critical.
Fast Operation
„ Less than 6 milliseconds typical transfer time is
invisible to sensitive electronic equipment, and
well within CBEMA and ITIC curves.
„ Automatically transfers from the failing power
source to the good source immediately upon
detection of a problem.
„ Manual transfer allows you to switch power
sources at your convenience for scheduled
source shutdowns or maintenance.
