An automatic transfer switch (ATS) is a self-acting, intelligent power switching device governed by dedicated control logic. The
principal purpose of an ATS is to ensure the continuous delivery of electrical power from one of two power sources to a connected
load circuit (electrical equipment – lights, motors, computers, etc.). The control logic or automatic controller is typically microprocessor-based and constantly monitors the electrical parameters
(voltage, frequency) of primary and alternate power sources. Upon failure of the connected power source, the ATS will
automatically transfer (switch) the load circuit to the other power source (if it is available). As a general rule, most automatic
transfer switches seek connection to the primary power source (utility) by default and will only connect to the alternate power
source (engine-generator, backup utility) when required (primary source failure) or requested to do so (operator command).

Products Description
Summary
Low-voltage automatic transfer switch assemblies provide a reliable means of transferring essential load connections between primary and alternate sources of electrical power. Data centers, hospitals, factories and a wide range of other facility types that require continuous or near-continuous uptime typically utilize an emergency (alternate) power source such as a generator or a backup utility feed when their normal (primary) power source becomes unavailable.

A typical transfer sequence includes:
1. The normal utility power source fails.
2. The transfer switch shifts the load to the emergency power source when power from the generator or backup utility feed is stable and within prescribed voltage and frequency tolerances. Depending on a facility’s needs and preferences, the transfer process is self-acting or manually-initiated.
3. The transfer switch returns the load from the emergency power source to the normal power source when utility power is restored. The re-transfer process is self-acting or manually-initiated.
