Product Overview: Engineered for Uncompromising Reliability

The Prostar ET LV Series is not just a power backup; it's a comprehensive power protection solution for the most demanding low-voltage environments. This 3-phase, 3:3 topology UPS is meticulously engineered to provide seamless, uninterrupted power to critical infrastructure, including data centers, industrial networks, telecommunications hubs, and financial systems. Its core architecture is built around the principle of "zero transfer time," ensuring that sensitive equipment never experiences a power gap, even during a complete mains failure. This is achieved through its true online double-conversion technology, which continuously conditions the incoming power and provides a pure sine wave output, making it compatible with any type of load, from delicate servers to heavy industrial machinery.
