Major Features

The APC Universal Transfer Switches (UTSs) include a variety of features and options that provide

maximum flexibility, and enhance operating reliability and efficiency.

Power Distribution to Up to Ten Circuits From Two Power Sources

The APC fully automatic Universal Transfer Switches (UTSs) supply power to multiple circuits in your

home or small office from one or two independent backup sources, such as a generator, UPS, solar

inverters or other alternative energy sources.

The UTS6 can support up to six single-pole circuits. The UTS6BI supports four single-pole circuits and

one double-pole circuit, and the UTS10BI supports up to eight single-pole circuits and one double-pole

circuit. Hard wired loads such as furnaces, well pumps, and sump pumps are also supported.

Quick, Safe and Easy Installation and Setup

The UTSs provide a safe and convenient way to connect a generator, uninterruptible power supply (UPS)

and other backup power sources to supply power to circuits used by essential home automation devices and

appliances, and computing and entertainment equipment during power outages.

Adaptive Load Management

With conventional transfer switches you must manage loads manually to prevent generator overload. The

UTS’s adaptive load management (ALM

) feature allows you to power more loads during an extended

blackout by intelligently turning off circuits that may otherwise overload your generator, or your backup

power source (UPS). Loads that are disconnected due to power surges or overloading are automatically

reconnected when the power surge, or overload condition no longer exists. The principles of ALM are

illustrated in Figure 2-1, and explained further in the Time Management and Load Shedding description

that follows Figure 2-1.
