The Ultra Power EL-3K is a tower-style uninterruptible power supply designed to keep your critical equipment running during outages. With a capacity of 3000VA and 2100W, it provides a pure sine wave output, which is essential for the stable operation of sensitive electronics. You can connect your devices through three Schuko sockets, while the front-mounted LCD display allows you to monitor the system status at a glance. Inside the 34.5 kg chassis, the unit utilizes four 12V 9Ah sealed maintenance-free lead-acid batteries operating at DC 48V. These batteries typically recover 90% of their capacity within 6 to 8 hours of charging. To ensure safety, the system includes a breaker for overcurrent protection and automatic shutdown mechanisms that trigger if the load exceeds 110% or 120% of its capacity. This UPS is well-suited for users who need reliable power backup and communication line protection via the included RJ11/RJ45 ports. It also features a USB port for connectivity and an auto-restart function that brings your systems back online as soon as AC power is restored. Measuring 455 x 195 x 330 mm, it fits easily into a dedicated equipment space.
