2.3.1 Advanced Battery Management
Advanced Battery Management technology uses sophisticated sensing circuitry and a three-stage
charging technique that extends the useful service life of UPS batteries while optimizing the battery
recharge time. ABM also protects batteries from damage caused by high current charging and
inverter ripple currents. Charging at high currents can overheat and damage batteries.
In charge mode, the batteries are recharged. Charging lasts only as long as it takes to bring the
battery system up to a predetermined float level. Once this level is reached, the UPS battery charger
enters float stage and the charger is operating in constant voltage mode.
Rest mode begins at the end of charge mode; that is, after 48 hours of float charging (customer
adjustable). In Rest mode, the battery charger is completely turned off. The battery system receives
no charge current during this rest period of about 28 days (customer adjustable). During Rest mode,
the open circuit battery voltage is monitored constantly, and battery charging is resumed when
necessary.
2.3.2 Powerware Hot Sync
Eaton Powerware Hot Sync technology is an algorithm that eliminates the single point of failure
in a parallel system and therefore enhances the system reliability. The Hot Sync technology is
incorporated in all Eaton 93PM UPSs, and it is utilised in both multi-module internal parallel and
external parallel systems.
Hot Sync technology enables all uninterruptible power modules (UPMs) to operate independently in
a parallel system, even without inter-module communications. The power modules utilising the Hot
Sync technology are completely autonomous; each module monitors their own output independently,
to remain in complete synchronization with the other modules. The UPM power modules share the
load perfectly even in changing capacity or changing load conditions.
Powerware Hot Sync technology combines digital signal processing and an advanced control
algorithm to provide automatic load sharing and selective tripping in a parallel UPS system. The load
share control algorithms maintain synchronization and load balance by constantly making minute
adjustments to variations in the output power requirements. The modules conform to demand
and are not in conflict with each other for the load. Powerware Hot Sync systems are capable of
paralleling for both redundancy and capacity.
2.4 Software and connectivity features
2.4.1 Customer interface
Mini-Slot Communication Bays — there are three communication bays for mini-slot connectivity cards.
Mini-slot cards are quickly installed and are hot-pluggable. See Chapter 5 Communication interfaces
on page 53 for additional information.
2.4.2 Power Management Software
Intelligent Power software products offer tools for monitoring and managing power devices across
the network. See Chapter 5 Communication interfaces on page 53 for more information.
