2.3. Features of the UPS

Eaton UPS has a variety of features to ensure cost effectiveness, and consistent and reliable power
supply protection. This section will provide a brief summary about the standard features of the UPS.
2.3.1.

Advanced Battery Management(ABM)

Precise sampling route and 3-stage charging technology are employed for advanced battery
management (ABM), which can prolong the service life of the UPS battery while also increasing
the charge speed. The ABM technology can prevent battery damage that might be caused by bulk
charge and ripple current of the inverter. Bulk charge may cause battery overheat and damage.
In charge mode, the UPS will charge the battery. The battery is charged to the floating charge
voltage preset in the system. When the battery reaches the floating charge voltage, the UPS
battery charger enters the floating charge stage and begins to charge the battery at a constant
voltage.
Upon completion of charge, it will enter sleep mode, namely after 48h floating charge (adjustable).
In sleep mode, the battery charger is turned off completely. In sleep mode that lasts around 28
days (adjustable), the battery is not charged by any charging current. In sleep mode, the UPS will
monitor the battery voltage constantly, and recharge the battery where necessary.
2.3.2.

Eaton HotSync wireless parallel technology (HotSync)

As Eaton HotSync wireless parallel technology (HotSync) is a control algorithm for removing
single-point failure, it can improve the reliability of the system.
The external parallel system of 93PR UPS employs the HotSync technology.
There is no communication among internal modules within the parallel system. The HotSync
technology can ensure the independent operation of every UPS.
In the parallel UPS system, Eaton HotSync wireless parallel technology is integrated with
digital signal processing and advanced control algorithm to realize automatic even load
distribution and selective disconnection. The even load distribution control algorithm can make
transient adjustment constantly in accordance with the output power requirements to maintain
synchronization and load balance. Each follows the load requirements and will not conflict
with others. Eaton HotSync technology can realize parallel redundancy and parallel capacity
expansion.
