The Ultra Power EL-1K is a tower-style uninterruptible power supply designed to keep your electronics running safely during power outages. With a capacity of 1000VA / 700W, it provides a pure sine wave output, which is essential for the stable operation of sensitive equipment. You can easily monitor the system's status via the front-panel LCD display, while the unit handles input voltages between 145 and 275Vac. To ensure your hardware remains protected, it includes a breaker for overcurrent protection and automatic shutdown mechanisms that trigger if the load exceeds 110% to 120% of its capacity. Inside the black chassis, the system relies on two sealed, maintenance-free 12V 7.5Ah lead-acid batteries operating at 24V DC. These batteries typically recover 90% of their capacity within 6 to 8 hours of charging. The device is built for reliability, featuring automatic restart when AC power returns, low voltage protection, and safeguards against short circuits. For connectivity, it offers two Schuko sockets, a USB port, and RJ45/RJ11 ports to protect your data lines from surges. Measuring 405 x 145 x 220 mm and weighing 23.8 kg, this UPS is a sturdy addition to a home office or small server setup. It is well-suited for users who need a dependable power bridge to save their work and shut down systems gracefully, knowing their equipment is shielded by a fast transfer time of typically 2 to 6ms.
