Line-Frequency UPSemploys thyristor (SCR) rectification at 50/60Hz and features a built-in output isolation transformer. This robust design provides exceptional overload capacity, strong surge immunity, and galvanic isolation that reduces common-mode noise and zero-ground voltage issues. The transformer also offers inherent fault isolation, protecting critical loads from DC injection in the event of inverter failure. Widely deployed in industrial plants, petrochemical facilities, heavy manufacturing, and mission-critical infrastructure where reliability and durability are paramount.
