The APC Smart-UPS series protects your critical data with reliable, uninterruptible power supply. The SMT3000RMI2U in a rack enclosure offers a capacity of 3000 VA with a maximum output power of 2700 watts. In the event of a power outage, the device ensures independent power supply for 3 to 11 minutes (at 100%/50% load). Its LCD display continuously shows key data such as operating mode and efficiency, voltage, frequency, and energy consumption. An intuitive menu facilitates the operation of all device functions. For management via computer, a USB and a serial RS-232 interface are available. With the SmartSlot, you can expand the 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 the battery's lifespan.
