RS232 + Dry Contact
The EA900 is equipped with a multifunctional RS232 port. This can be used for dry contact, supplying relay functionality for a low battery, AC fail, and other common failures of custom-wired applications. It can also be connected to a computer or server for the standard shutdown software.

Standard Shutdown Software
The EA900 comes with standard software which can automatically shutdown the server or computer when a power failure occurs. This software allows the UPS to instruct the operating systems to close down a PC when it is running unattended. Users can set the parameters with which to schedule when the computer or server should shutdown, making sure that no significant data is lost and important backups are created. Updates will be automatically sent by email, so that users are always aware of what is happening, even at remote locations.

Communication Slot
The multifunctional communication slot is conveniently located at the back of the UPS and can be used to accommodate a variety of accessory cards. The wide range of cards that are available means that the EA900 can be used for various applications and in numerous locations.

SNMP Card
The SNMP card allows users to connect the EA900 directly to the ethernet network and the internet. This solution means that you can conveniently monitor and manage the UPS with a standard web browser, while simultaneously being able to shutdown multiple computers and operating systems over the network.

Environmental Card
The environmental card provides the functionality with which to remotely monitor environmental and UPS conditions using a standard web browser, SNMPview, or third-party network management software. Users can observe the ambient temperature, humidity, or the presence of water in the remote location, along with the status of additional contact devices such as a smoke detector or an open-door/window sensor.

Relay I/O Card
The Relay I/O card can be inserted in the SNMP slot at the back of the UPS, providing dry contact relay outputs for custom-wired applications and delivering support for the built-in shutdown of AS/400 systems. This option provides contact closures for the remote monitoring of alarm conditions in the UPS, delivering signals for On Battery, On Bypass, Low Battery, Summary Alarm, UPS Fault and On UPS.

GPRS Card
The GPRS card can be used with the EA900 and enables the user to have an in depth overview of the status of the UPS and the power at a particular location without any network or internet connection. The status can be viewed using the web interface, an SNMPview or third-party network management software. As long as there is GPRS coverage, you will be able to deploy this card.

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.
