DYNAMIC VOLTAGE RESTORER
The DOS DVR is a highly reliable power‑supply solution that leverages energy‑storage technology and seamless voltage‑source switching. Featuring an all‑modular design, it enables rapid on‑site installation, supports N+1 redundancy across multiple modules, and allows flexible expansion or reduction of capacity. Primarily addressing voltage sags, the device can detect voltage anomalies within 0.3 ms and, via its inverter and energy‑storage unit, fully compensate for voltage sags and surges of any depth and type within 2 ms. It can also protect against voltage interruptions lasting up to 30 seconds. With overall efficiency exceeding 99%, it represents an excellent alternative to UPS systems.
