Introduction

Load Management The Freedom SW 3000 has a built-in transfer relay that connects your inverter output or AC input from the utility grid or generator to your loads. Because the usual AC power sources such as campground outlets or small generators often have limited current availability, having the capability to manage your AC loads is extremely valuable. The Freedom SW 3000 provides a number of features to facilitate this:

•The charger is power factor corrected to use AC current as efficiently as possible and only requires 22 amps to provide rated charger output. Minimizing the AC current used by the charger means more current is available for your AC loads.

•Freedom SW 3000 has a power share feature which prioritizes your AC loads by reducing the charge current and maintaining the total input current to less than your breaker setting or the breaker setting.

•Occasionally, AC input sources have low voltage. To avoid loading these weak sources any further, the charger automatically reduces its AC current draw as the AC voltage approaches the minimum acceptable level.

Xanbus® System

The Xanbus system includes the Freedom SW 3000 and other Xanbus- enabled devices. The Freedom SW 3000 is the device in a Xanbus system that typically provides network power—500 mA at 12 volts DC. All of the Xanbus-enabled devices, such as the Freedom SW 3000, the System Control Panel (SCP), and the Automatic Generator Starter (AGS) are able to communicate their settings and activity to each other. See Figure 1.
