Unique Features.

Advanced Battery Management

The EA900 series is equipped with a sophisticated three step charger for efficiently charging the UPS while prolonging battery life.
Step 1 The charger provides a constant charge current until the battery has reached 80% of its capacity, meaning that the UPS is ready to operate again when a new power failure occurs.
Step 2 The charge voltage is held constant for about 60 minutes, allowing the charge current to gradually decline towards the end of this period. The battery will now have been charged to about 90% of its capacity.
Step 3 The charge voltage drops to a float-charge in order to compensate for self discharge, thereby prolonging the life of the batteries.

Optional Extended Runtime

The EA900 series can be upgraded with extra battery packs, allowing users to increase runtime from several minutes up to several hours.

Hot-swappable Battery Design.

The EA900 series’ battery packs are hot-swappable and user replaceable, meaning that downtime during maintenance or replacement is kept to a minimum.
