The Smart-UPS series from APC protects your critical data with reliable, uninterruptible power supply. The SRT5KRMXLI in a rack enclosure offers a capacity of 5000 VA with a maximum output power of 4500 watts. Its LCD display continuously shows key parameters such as operating mode and efficiency, voltage, frequency, and energy consumption. A clear menu ensures intuitive operation of all device functions. For management via computer, there are USB, RJ-45 10/100 Base-T, and RJ-45 serial interfaces available. The SmartSlot allows you to expand device functions according to your needs. 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 charging voltage is adjusted to the battery temperature, allowing for particularly gentle charging, which positively impacts battery life. High efficiency helps keep power consumption and cooling requirements low, thereby benefiting both the environment and budget. This is a combination device for rack/tower (rack height 12U). The connection and commissioning of a UPS with over 3.5 kVA must be coordinated in advance with the local electricity provider. The connection must be made by an electrician.
