The Model LTN-3R uninterruptible power supply (UPS) features a NEMA 3R raintight enclosure. The outdoor-rated UPS provides output line voltage regulation of ±3%, magnetic isolation, filtering, and power conditioning. Available in 550VA to 1.3kVA single-phase sizes, the no-break, continuous sinewave unit offers extended battery back-up from 30 min. to 9.5 hr without the need for additional enclosures. In addition, an integral constant voltage transformer isolates and regulates output voltage, while elastomeric insulation prevents condensation and internal moisture within the product. Conformal coated circuit boards are moisture-resistant as well.
