The expansion slot "SmartSlot" is already occupied in this model. Included in the package is the network expansion AP9631, which adds a LAN interface to the UPS. This allows for convenient remote management as well as quick notifications in case of problems, enabling a rapid response to critical situations. Additionally, the expansion card allows for monitoring the temperature of external devices. The C13 power outlets are divided into three groups, with their behavior in the event of a power outage being flexibly configurable. For example, non-critical peripheral devices can be disconnected from the power supply to save battery. The sealed lead-acid battery with gelled electrolyte is completely maintenance-free. The UPS calculates the expected battery life and detects premature aging through regular battery tests. The voltage applied during charging is adjusted according to the battery temperature, allowing for particularly gentle charging, which positively impacts the lifespan. A high efficiency of typically over 90% helps to keep power consumption and cooling requirements low, thus benefiting both the environment and the budget.
